Gasoline-OilRecommended Gasoline

The recommended gasoline to use in thesesnowmobiles is 87 octane regularunleaded. In many areas, oxygenates(either ethanol or MTBE) are added to thegasoline. Oxygenated gasolines contain-ing up to 10% ethanol or up to 15%MTBE are acceptable gasolines; however,on the Bearcat 570/T570 models when-ever using oxygenated gasolines, the car-buretor main jet must be one size largerthan the main jet required for regularunleaded gasoline. For example, if a 220main jet is recommended for regularunleaded gasoline, a 230 main jet must beinstalled if using an oxygenated gasoline.

NOTE: The TZ1 Turbo models willdetect lower octane gasoline andreduced engine performance willresult. It is recommended that 91octane (minimum) gasoline be usedin these models.

When using ethanol blended gasoline, it isnot necessary to add a gasoline antifreezesince ethanol will prevent the accumula-tion of moisture in the fuel system.

Recommended Injection Oil (Bearcat 570/T570 Models)

The recommended oil to use in the oil-injection system is Arctic Cat Formula 50Injection Oil (p/n 5639-475 - qt) or (p/n5639-476 - gal.). This oil is specially for-mulated to be used either as an injectionoil or as a pre-mix oil (for break-in) andmeets all of the lubrication requirementsof the Arctic Cat snowmobile engine.

Recommended Engine Oil (Bearcat Z1 XT/TZ1 Models)

The recommended oil to use is Synthetic0W-40 Oil (p/n 5639-172 - qt) or (p/n5639-173 - gal.).

After the engine break-in period, theengine oil should be changed every 2500-3000 miles on the non-turbo models or1500-2000 miles on the turbo model andbefore prolonged storage.

Filling Gas Tank

Since gasoline expands as its temperatureincreases, the gas tank must be filled toits rated capacity only. Expansion roommust be maintained in the tank particu-larly if the tank is filled with cold gaso-line and then moved to a warm area.

Also, if the snowmobile is to remain on atrailer after filling the gas tank, the bed ofthe trailer must be maintained level toprevent gasoline from draining outthrough the gas tank vent hose.

Break-In Gas/Oil Mixing Instructions (Bearcat 570/T570 Models)

Before mixing gasoline and oil, makesure the oil is at room temperature (20°C/68° F). Use a U.L. approved 22.7 l (6U.S. gal.) gasoline container for mixingthe gasoline and oil. To properly mix thefuel at a 100:1 ratio, use the followingprocedure:

CAUTIONIf a situation arises wherein 91octane gasoline is not available, 87octane gasoline can be substituted;however, do not prolong the usageof 87 octane gasoline as it will causepoor engine performance.

CAUTIONDo not use white gas or gasolinescontaining methanol. Only ArcticCat approved gasoline additivesshould be used.

CAUTIONAny oil used in place of the recom-mended oil could cause seriousengine damage.

! WARNINGAlways fill the gas tank in a well-ven-tilated area. Never add gasoline tothe snowmobile gas tank near anyopen flames or with the engine run-ning. DO NOT SMOKE while fillingthe gas tank. Do not sit on the snow-mobile without first installing the gastank cap.

6

1. Pour gasoline into the gasoline con-tainer until approximately half full.

2. Pour 236 ml (8 fl oz) of the recom-mended 2-cycle oil into the gasolinecontainer.

3. Install cap on gasoline container andshake the mixture vigorously.

4. Fill the gasoline container with gaso-line; then cap the gasoline containerand shake the mixture vigorously.

5. Using a fine-mesh screened funnel,pour the fuel mixture from the gaso-line container into the snowmobilegas tank.

Engine Break-InThe Arctic Cat engine (when new orrebuilt) requires a short break-in periodbefore the engine is subjected to heavyload conditions.

Bearcat 570/T570 Models

Arctic Cat requires that the first tankfulof fuel be premixed at a 100:1 ratio in alloil-injection models.

During the break-in period, a maximumof 1/2 throttle is recommended; however,brief full-throttle accelerations and varia-tions in driving speeds contribute to goodengine break-in. After one (1) tankfulbreak-in period, the snowmobile may betaken to an authorized Arctic Cat Snow-mobile dealer for a checkup. Thischeckup is at the discretion and theexpense of the snowmobile owner.

Bearcat Z1 XT/TZ1 Models

This engine does not require any pre-mixed fuel during the break-in period.

To ensure trouble-free operation, carefuladherence to the following break-inguidelines will be beneficial.

* With occasional full-throttle operation.To ensure proper engine break-in, ArcticCat recommends that the engine oil andfilter be changed after 500 miles. Thisservice is at the discretion and expense ofthe snowmobile owner.

Drive Belt Break-InDrive belts require a break-in period ofapproximately 25 miles. Drive the snow-mobile for 25 miles at 3/4 throttle or less.By revving the engine up and down (butnot exceeding 60 mph), the exposed cordon the side of a new belt will be worndown. This will allow the drive belt togain its optimum flexibility and willextend drive belt life.

CAUTIONNever mix oil and gasoline in thesnowmobile gas tank.

! WARNINGAlways fill the gas tank in a well-ven-tilated area. Never add gasoline tothe snowmobile gas tank near anyopen flames or with the engine run-ning. DO NOT SMOKE while mixingfuel or filling the gas tank.

CAUTIONDO NOT exceed the one (1) tankfullimitation of a 100:1 gas/oil break-inmixture. Continuous use of a gas/oilmixture, unless consistently operat-ing in extremely cold conditions (-26°C/-15°F or colder), could causespark plug fouling and excessivecarbon buildup. A 100:1 gas/oil mix-ture must be used in conjunctionwith the oil-injection system toensure adequate engine lubricationin extremely cold conditions.

CAUTIONDO NOT use premixed fuel in thesnowmobile gas tank. Engine dam-age will occur.

NOTE: Before starting the snow-mobile in extremely cold tempera-tures, the drive belt should beremoved and warmed up to roomtemperature. Once the drive belt is atroom temperature, install the drivebelt (see Drive Belt sub-section inthe Maintenance section).

Cold Drive-Away Function (Bearcat Z1 XT/TZ1 Models)On these models, there is a “cold drive-away” function incorporated within theengine.

NOTE: On models with a StandardGauge when cold-starting theengine, the coolant temperaturewarning icon will illuminate and thereadout screen will display TEMP.With the engine in this temperaturerange, the RPM “limit” of the enginewill be below drive system engage-ment speed. As the engine warms,the TEMP display will go out, thecoolant temperature warning iconwill begin to flash, and the RPM“limit” of the engine will increaseallowing the snowmobile to movewithout full-throttle operation. Whenthe engine reaches proper operatingtemperature, the coolant tempera-ture warning icon will go out.

NOTE: On models with a DeluxeGauge when cold-starting the engine,the coolant temperature warning iconwill illuminate and the TEMP displayon the readout screen will begin toflash. With the engine in this temper-ature range, the RPM “limit” of theengine will be below drive systemengagement speed. As the enginewarms, the coolant temperaturewarning icon will begin to flash, theTEMP display will continue to flash,and the RPM “limit” of the engine willincrease allowing the snowmobile tomove without full-throttle operation.When the engine reaches properoperating temperature, the coolanttemperature warning icon and theTEMP display will go out.

Speedometer/TachometerThese snowmobiles are equipped withdifferent speedometer/tachometer styles.Determine which style your model isequipped with and use the appropriatefollowing information.

Indicator Icons (Standard Gauge)

Certain models (Bearcat models, T570model, and TZ1 standard model) areequipped with a standard gauge combina-tion speedometer/tachometer. Indicatoricons are incorporated within the speed-ometer/tachometer. Also incorporatedinto the speedometer/tachometer is a dig-ital readout screen.

CAUTIONNever run the engine with the drivebelt removed. Excessive revving of theengine could result in serious enginedamage and drive clutch failure.

CAUTIONIt is extremely important that theengine is properly warmed up beforesubjecting the engine to high speedoperation or heavy loads. Theengine should be allowed to idle atleast 3-4 minutes before it is oper-ated at more than 1/2 throttle. Inextremely cold conditions, thewarm-up time will be longer. Coldseizure and piston scuffing causedby insufficient warm-up will not becovered by warranty. Also, do notidle the engine for excessively longperiods of time.

Low Oil Warning Icon (Bearcat 570/T570 Models)

The Low Oil Warning Icon is designed toalert the snowmobile operator when theoil in the oil injection reservoir getsbelow a prescribed level; however, it ishighly recommended that a visual verifi-cation of the oil level in the reservoir bedone prior to operating the snowmobile.Once the Low Oil Warning Icon illumi-nates during operation of the snowmo-bile, the operator must periodicallymonitor the level of oil in the reservoirand must fill the reservoir the next timegasoline is added to the gas tank. The“alert level” of the Low Oil Warning Iconis approximately equal to 1 tankful ofgasoline under normal operating condi-tions.

Oil Pressure Warning Icon (Bearcat Z1 XT/TZ1 Models)

The Oil Pressure Warning Icon indicatesengine oil pressure, not the oil level;however, if the oil level is low, it mayaffect oil pressure.

The icon should illuminate each time theignition switch is turned to RUN orSTART, and it should go out when theengine starts. If the icon illuminateswhile the engine is running, oil pressurehas been lost and the engine will auto-matically shut off.

If oil pressure is lost, use the followingprocedure to check the oil level:

1. With the engine off, remove theengine oil level stick and wipe itclean. Without screwing it in, set thestick back in the oil tank. Remove itand observe the oil level on thestick. If the oil level is at or belowthe ADD mark on the oil level stick,add only enough recommended oilto raise the level to the NORMALrange. DO NOT overfill the reser-voir with oil.

2. Open the air bleed bolt located onthe oil pump (beneath the coolanttank) to purge air from the oil hose.

Standard-Lug TrackAccelerated wear strip wear caused byoperating on hard-packed snow condi-tions is NOT covered under Arctic CatInc. warranty policy.

Track Studs NOTE: Stud or hooker plate instal-lation will void track and tunnel war-ranty.

NOTE: Stud installation can be per-formed by the snowmobile owner ifqualified to do so. If the owner doesnot feel qualified, take the snowmo-bile to an authorized Arctic Cat Snow-mobile dealer for this service. Thisservice is at the discretion andexpense of the snowmobile owner.

NOTE: To prevent tunnel damagefrom the studs, Tunnel Protector Kit(p/n 4639-771) for the Bearcat 570/T570 models or (p/n 5639-143) for theBearcat Z1 XT model must beinstalled.

For proper installation, use the followingprocedure:

1. Using the appropriate stud template(see chart), mark the desired studpattern to be used.

2. Using the proper-sized stud holedrill bit, drill out the stud holes.

3. Push the stud through the hole frominside the track; then place thedomed support plate and lock nut onthe exposed stud.

4. Using a wrench to secure the stud,tighten the lock nut on the exposed stud.

It is also recommended that wheneverstuds are installed on a track, carbidewear bars should be installed on the skis.Carbide wear bars complement the trackstuds to balance steering control underthese conditions. The length of the car-bide on the wear bars should be propor-tionate to the number of track studs (i.e.small number of track studs — shortlength of carbide...many track studs —long length of carbide). The proper pro-portion between the number of studs andcarbide length on the wear bar will main-tain steering balance.

CAUTIONIf installing studs on standardBearcat 570 model with a single-plytrack, studs with a head diameter ofat least 28.6 mm (1.125 in.) must beused.

! WARNINGWhen installing studs on a single-plytrack, it is important to use ArcticCat-approved studs (proper headdiameter). If approved studs (properhead diameter) are not used, studscould tear free of the track causingpossible injury or even death. Con-sult an authorized Arctic Cat Snow-mobile dealer for information.

Operating InstructionsStarting and Stopping EngineIt is imperative that the brake system bechecked for wear and proper operationand that all safety checks found in theaccompanying Snowmobile SafetyHandbook be performed before attempt-ing to start the engine. Also, on theBearcat 570/T570 models, be sure thecorrect carburetor main jets for theoperating temperature, altitude, andgasoline are being used. After theengine has been started, check the head-lights (high and low beam), taillight, andbrakelight to be sure they are workingproperly and adjusted correctly. Makesure all lights are clean to provide maxi-mum illumination. The headlight andtaillight must be clean and must be illu-minated whenever the engine is running.

1. Test the operation of the brake sys-tem by compressing the brake lever.The brake lever must feel firm whencompressed; then while holding thebrake lever in the compressed posi-tion, measure the distance betweenthe brake lever and the handlebar.The distance must be greater than2.54 cm (1 in.).

741-328C

2. Check the fluid level in the reservoir.The brake fluid level must be visiblein the sight glass. Add Arctic Catapproved brake fluid as necessary.

741-328A

NOTE: If the sight glass appearsdark, there is a sufficient amount offluid in the reservoir.

3. Test the throttle control lever bycompletely compressing and releas-ing it several times. The leverMUST return to the idle positionquickly and completely.

4. Move the emergency stop switch tothe UP or RUN position.

5. Insert key into ignition switch; thenrotate key to the RUN position.

6. On the Bearcat 570/T570 models fora cold engine, move the choke leverto the full-choke position. If theengine is warm, choking is normallynot necessary.

NOTE: On the Bearcat 570/T570models when the engine is beingstarted with aid of the choke, DONOT COMPRESS THE THROTTLECONTROL LEVER. If the throttle con-trol lever is compressed, the enginewill not start because the gas/airmixture will be too lean. To start awarm engine, however, the throttlecontrol lever may have to be com-pressed slightly.

NOTE: On the Bearcat Z1 XT/TZ1models when a cold engine is beingstarted, DO NOT COMPRESS THETHROTTLE CONTROL LEVER. If thethrottle control lever is compressed,the engine will not start because thefuel/air mixture will be too lean.

7. On Bearcat 570/T570 models withmanual start, pull the recoil handleslowly until resistance is felt; thengive a short quick pull. Repeat untilthe engine starts.

NOTE: In extremely cold weather,pull the recoil handle slowly two tothree times to begin the starting pro-cedure.

NOTE: On electric start models,rotate the key to the START position;then when the engine starts, releasethe key.

8. On the Bearcat 570/T570 modelswhen the engine starts, allow it towarm up for approximately 30 sec-onds with the choke lever in the full-choke position. After the 30-secondwarm-up, move the choke lever tothe middle position. The choke levershould be moved to the OFF posi-tion when engine is warm. Slightthrottle control lever compressionmay be necessary after the enginestarts and during warm-up. Idle theengine several minutes until theengine has reached normal operatingtemperature.

9. On the Bearcat Z1 XT/TZ1 models,there is a “cold drive-away” functionincorporated within the engine. Thisfunction is active until the enginereaches operating temperature (seeCold Drive-Away Function sub-sec-tion in the General Information sec-tion).

10. Flooding — On the Bearcat 570/T570 models if the engine does notstart when the choke is being usedbut seems ready to start, move thechoke lever to the OFF position.Engage the brake lever lock; thencompress the throttle control leverfully and try to start the engine.When the engine starts, release thethrottle control lever immediately.After the warm-up, release the brakelever lock.

NOTE: On the Bearcat 570/T570models if the engine fails to startduring the attempt with the throttlecontrol lever compressed, removethe spark plugs and clean and drythem thoroughly or install a new setof properly gapped, recommendedspark plugs.

11. Flooding — On the Bearcat Z1 XT/TZ1 models if the engine does notstart but seems ready to start, engagethe brake lever lock; then compressthe throttle control lever fully and tryto start the engine. When the enginestarts, release the throttle controllever immediately. After the warm-up, release the brake lever lock.

NOTE: On the Bearcat Z1 XT/TZ1models if spark plugs must bereplaced, take the snowmobile to anauthorized Arctic Cat Snowmobiledealer for inspection and service.This service is at the discretion andexpense of the snowmobile owner.

12. To shut off the engine, turn the igni-tion key to the OFF position or pushthe emergency stop switch to theDOWN position.

BrakingThe following items are items that theoperator must be familiar with whenoperating this snowmobile and itshydraulic brake system. Important addi-tional information on the proper mainte-nance of the brake system is found in theMaintenance section.

1. Use the brakes wisely. Each time thebrakes are applied in all hydraulicbrake systems (including automotiveapplications), heat is transferred tothe brake fluid. The amount of heattransferred during high speed stopsand/or repetitive use may be highenough to boil the brake fluid andcause the brakes to either fade or maycause an unexpected loss of brakes.

If this occurs, the brake fluid requiresa cool-down period before the brakeswill again function properly. Thiscool-down period will vary depend-ing upon the ambient air temperatureand the temperature of the brakefluid. If loss of brakes has occurredbecause of high fluid temperatures,do not operate the snowmobile untilthe cool-down period has expired andbrake lever firmness has returned.

2. Be sure to maintain the brake fluid atthe proper level and take care not toget any moisture in the system asmoisture in the brake fluid lowers theboiling point. If the brake fluid is everboiled (by high speed stops or repeti-tive use) or if moisture is allowed toenter the system, it must be changed.Never substitute or mix different typesor grades of brake fluid.

3. Never ride the brake. Even main-taining minimal pressure on thebrake lever will cause the brake padsto drag on the disc and may overheatthe brake fluid.

CAUTIONOn the Bearcat Z1 XT/TZ1 models,always turn the ignition switch key tothe OFF position when the snowmo-bile is not being used. Leaving theignition switch in the ON position willresult in discharging the battery andpossible damage to the battery.

! WARNINGExcessive repetitive use of thehydraulic brake for high speed stopswill cause overheating of the brakefluid and premature brake pad wearwhich will result in an unexpectedloss of brakes.

! WARNINGUse only Arctic Cat approved brakefluid. Never substitute or mix differ-ent types or grades of brake fluid.Brake loss can result. Check brakefluid level and pad wear before eachuse. Brake loss can result in severeinjury or even death.

25

4. The brake lever lock is not a parkingbrake and should not be applied forperiods exceeding 5 minutes.NEVER OPERATE THE SNOW-MOBILE WITH THE BRAKELEVER LOCK ENGAGED.

5. Pumping the brake lever is permissi-ble; however, if pumping the brakelever more than twice is necessary toobtain the necessary stopping power,immediately take the snowmobile toan authorized Arctic Cat Snowmobiledealer for service. If not under war-ranty, this service is at the discretionand expense of the snowmobile owner.

6. When new brake pads are installed, a“burnishing” process is required.Drive the snowmobile slowly andcompress the brake lever several timesuntil the pads just start to heat up; thenallow them to thoroughly cool down.This process stabilizes the pad materialand extends the life of the pads.

Emergency StoppingThere are several methods of stopping orslowing the snowmobile under a varietyof situations. Identified in the followingchart are the ways a snowmobile may bebrought to a stop and the effectivenessunder normal conditions.

Throttle/Ignition Monitor SwitchThe throttle control is equipped with amonitor switch for safety purposes whichwill stop the engine when a loss of returnspring force occurs. If ice forms in thethrottle system or if there is some othermalfunction of the throttle system result-ing in a loss of return spring force, themonitor switch will stop the engine whenthe throttle control lever is released.

If the snowmobile engine stops abruptlywhen the throttle control lever is releasedand the activation of the monitor switch issuspected, use the following procedure:

1. Rotate the ignition key to the OFFposition.

2. Remove ice and snow from thethrottle system and wait 5-10 min-utes for the engine heat to thaw icefrom the throttle system.

3. Test the throttle control lever bycompressing and releasing it severaltimes. The lever MUST return to theidle position quickly and completely.

NOTE: If the throttle control leveroperates properly and the enginedoes not start, compress the throttlelever slightly (approximately 1/8throttle) and try starting the engine.If the engine now starts and stopswhen the throttle lever is released,take the snowmobile to an autho-rized Arctic Cat Snowmobile dealerfor service. If not under warranty,this service is at the discretion andexpense of the snowmobile owner.

! WARNINGThe brake lever lock is not a parkingbrake and should not be applied forperiods exceeding 5 minutes. Thebrake lever lock maintains the brakelever in the compressed position andmaintains pressure against the brakedisc; however, after a period of time,the pressure applied to the brake discmay relax below the amount requiredto hold the snowmobile stationary.

Fuel System

In-Line Fuel Filter (Bearcat 570/T570 Models)

Arctic Cat recommends that the in-linefuel filter be checked weekly. The in-linefuel filter is located just in front of thefuel pump inlet fitting. The filter must beclean to allow the fuel hose to transmitthe amount of gasoline required.

If the in-line fuel filter is obstructed, gas-oline flow will be restricted; therefore,the filter must be replaced. To removeand install the in-line fuel filter, use thefollowing procedure:

1. Pinch off the fuel hose between thegas tank and fuel filter.

2. Remove and discard the clamps;then pry the fuel hoses off the in-linefuel filter and remove the filter.

NOTE: The in-line fuel filter mustbe replaced if obstructed. Filters areavailable from an authorized ArcticCat Snowmobile dealer.

CAUTIONFailure to inspect the air filter fre-quently if the snowmobile is used inadverse conditions can damage theturbocharger/engine.

CAUTIONDo not use compressed air in anattempt to clean the filter. Damage tothe filter may occur. If the filter isdirty, it must be replaced.

CAUTIONA torn air filter can cause damage tothe turbocharger/engine. Contami-nants may get inside the turbo-charger/engine if the filter is torn.Carefully examine the filter for holesor tears. Replace the filter with a newone if it is torn.

CAUTIONDo not run the engine without the airfilter installed. Severe damage to theturbocharger/engine will occur.

! WARNINGWhenever any maintenance orinspection is made on the fuel sys-tem in which there may be fuel leak-age, there should be no welding,smoking, open flames, etc., in thearea.

4. In turn on each carburetor, place afinger lightly against the side of thepiston valve; then rotate the carbure-tor adjuster counterclockwise untilslight upward movement of thevalve is noted.

5. Check to make sure the valves startto open at the exact same moment byplacing a thumb and finger againstthe valves; then lightly compress thethrottle lever.

NOTE: If an individual piston valvestarts to open before another, rotatethe adjuster on the valve which islifting first clockwise, just enough tosynchronize the valves. Recheck byrepeating steps 2-5.

6. With the piston valves synchronized,tighten the adjuster jam nutssecurely; then slide the insulatorsonto the adjusters.

NOTE: There must be free-play inthe throttle lever.

7. In turn on each carburetor, place afinger against the piston valve.Rotate the idle speed screw clock-wise until it contacts the valve.

8. Compress the throttle lever to thefull-open position; then rotate eachidle speed screw clockwise 2 com-plete turns. Release the throttlelever.

NOTE: There must be 0.75-1.5 mm(0.030-0.060 in.) free-play betweenthe throttle lever and the controlhousing.

9. At this point, there must be 0.75-1.5mm (0.030-0.060 in.) of cable free-play gap in the throttle lever. If thereis no cable free-play in the throttlelever, the throttle safety switches willnot function properly, and the enginewill cut out in the idle position.

0741-518

NOTE: If cable free-play gap is notcorrect, rotate each adjuster anequal amount until recommendedfree-play is achieved. Each pistonvalve must be resting against the tipof its idle speed screw.

NOTE: If throttle cable free-play isincorrect, the carburetor safetyswitches will be activated prema-turely and the engine will not start.

Fine-Tuning Pilot Air Screws and Idle Speed Screws (External)

1. While counting the rotations, care-fully rotate the pilot air screwsclockwise until lightly seated.

2. Rotate the pilot air screws counter-clockwise the exact number of rota-tions ± 1/4 turn from the seatedposition as an initial setting.

3. Install the air-intake silencer bootstaking care that the boots are properlypositioned and that the boots are not“folded” in the air-intake silencercausing a restriction of air flow.

4. With the snowmobile on a shieldedsafety stand, start the engine, releasethe brake lever lock, and thoroughlywarm up.

! WARNINGBe sure to tighten the adjuster jamnuts securely. If an adjuster jam nutis not tightened, the adjuster canrotate out of the carburetor capcausing the piston valve not toreturn to the full-closed position.

CAUTIONDo not force a pilot air screw whenrotating it clockwise; damage to thepilot air screw needle tip will result.

38

NOTE: Make engine idle adjust-ment only after the engine hasreached running temperature. Sincethe idle speed screws have not beenfine-tuned, slight throttle pressuremay be necessary to keep the enginerunning. Allow engine to warm up for2-3 minutes.

5. After the engine has been thor-oughly warmed up, fine-tune thepilot air screws (equally) and theidle speed screws (equally) until theengine runs smoothly.

NOTE: Engine idle should bewithin a range of 1600-1700 RPM.

6. Test the throttle control lever bycompressing and releasing it severaltimes. The lever must return to theidle position quickly and completely.

Calibrating Main Jets/Pilot Jets/Jet Needle E-Clips (Internal)

Altitude, temperature, and the use of oxy-genated gasoline affect the carburetionneeded for optimum engine performance.The carburetor main jets must bechanged in conjunction with changes inoperating altitude, oxygenated gasolineusage, and temperature. Also, the pilotjets and jet needle E-clip positions mayhave to be changed with changes in oper-ating altitude. To change pilot jets and E-clip positions, the carburetors must beremoved and disassembled (float cham-ber, etc.). Arctic Cat highly recommendsthat this service be done by an authorizedArctic Cat Snowmobile dealer only.

NOTE: The following internal car-buretor calibrations may be done bythe snowmobile owner if qualified todo so. If the owner does not feelqualified, take the snowmobile to anauthorized Arctic Cat Snowmobiledealer for this service. This serviceis at the discretion and expense ofthe snowmobile owner.

As the ambient temperature rises or asthe snowmobile is operated at a higheraltitude, the main jets must be replacedwith leaner main jets. The original equip-ment (production) main jets may need tobe changed (depending on the type ofgasoline you are using, your operatingaltitude, and temperature). A CarburetorJet Chart decal is located on the beltguard of the snowmobile. It should benoted that when selecting the propermain jets, it is better to be too rich ratherthan too lean. To change carburetor mainjets, use the following procedure:


! WARNINGIf a tachometer is not available, caremust be taken not to adjust engineidle speed too high.

CAUTIONIt is important that the pilot airscrews are adjusted equally and thatthe idle speed screws are adjustedequally.

! WARNINGDO NOT operate the snowmobilewhen any component in the throttlesystem is damaged, frayed, kinked,worn, or improperly adjusted. If thesnowmobile is operated when thethrottle system is not functioningproperly, personal injury couldresult.

Checking Spark Plugs

To see if the spark plugs being used are ofthe proper heat range (after the snowmo-bile has been operated under normal driv-ing conditions), remove the spark plugsand examine the condition of the centerelectrode insulator of each spark plug.

AO352A

A. TAN or LIGHT BROWN insula-tor indicates correct spark plugs(heat range).

B. LIGHT GRAY or WHITE insula-tor indicates over-heating of theengine. This condition is caused bya too lean condition or incorrectspark plugs (heat range too hot).

C. BLACK insulator indicates fuelin the combustion chamber is notburning completely. This condi-tion is caused by a too rich con-dition, too much oil, or incorrectspark plugs (heat range too cold).

NOTE: If the center electrode insu-lators are light gray, white, or blackand if the carburetor adjustments,oil-injection pump synchronization,and ignition timing are correct, dif-ferent heat-range spark plugs maybe necessary. Authorized Arctic CatSnowmobile dealers have detailedspark plug information. Consult adealer before changing spark plugs,as incorrect heat-range spark plugscould cause poor engine perfor-mance or engine damage.

3. Look through the clear side of thefuse to see if the metal wire inside isseparated. If it is, the fuse is blownand should be replaced with a fuse ofthe correct amperage rating.

4. On the Bearcat Z1 XT/TZ1 models,install the fuse panel cover and closethe right-side access panel. On theBearcat 570/T570 models, install thefuse holder cover.

Even after replacing a fuse, it may con-tinue to blow if the cause of the overloadis not determined. If the fuse continues toblow, take the snowmobile to an autho-rized Arctic Cat Snowmobile dealer forservice. If not under warranty, this ser-vice is at the discretion and expense ofthe snowmobile owner.

Brake SystemArctic Cat recommends that the brakesystem (brake lever, fluid reservoir, hose,caliper, pads, and brake disc) be checkeddaily for fluid leakage, wear, or damageand for proper operation. Also, the brakefluid level must be checked every timebefore starting the engine. The brakefluid must be visible in the sight glass.

Checking/Adding Brake Fluid

1. With sight glass reservoir in a levelposition, check the fluid level. Thebrake fluid level must be visible inthe sight glass.

NOTE: If the sight glass appearsdark, there is a sufficient amount offluid in the reservoir.

741-328A

2. If the brake fluid is not visible in thesight glass, remove the reservoircover and add Arctic Cat approvedbrake fluid until the fluid is at therecommended level. Install andsecure the reservoir cover. Do notallow moisture to contaminate thebrake system.

! WARNINGAlways replace a fuse with one hav-ing the same specified amperage rat-ing. Using a fuse with a higher ratingcan cause severe wire damage andcould start a fire.

! WARNINGDO NOT operate the snowmobilewhen the brake lever lock is engagedor when any component in the brakesystem is damaged, worn, oradjusted improperly. If the snowmo-bile is operated and the brake sys-tem is not functioning properly,severe personal injury could result.

CAUTIONBrake fluid is highly corrosive. Donot spill brake fluid on any surfaceof the snowmobile.

44

Changing Brake Fluid

The brake fluid must be changed on a reg-ular basis and whenever the brake fluidhas been overheated or contaminated. Thebrake fluid should be changed every 1000miles or at the end of the snowmobilingseason, whichever occurs first. Take thesnowmobile to an authorized Arctic CatSnowmobile dealer for this service. Thisservice is at the discretion and expense ofthe snowmobile owner.

Checking Brake Lever Travel

Before each use, check the brake levertravel using the following procedure:

1. Compress the brake lever fully.

NOTE: Do not pump the brakelever as it will produce an inaccuratereading.

2. Measure the distance between thebrake lever and the handlebar. Thedistance must be greater than 2.54cm (1 in.).

741-328B

3. If the resultant distance is less thanspecified, take the snowmobile to anauthorized Arctic Cat Snowmobiledealer for service. If not under war-ranty, this service is at the discretionand expense of the snowmobileowner.

Bleeding Brake System

If the brake lever feels spongy whenapplied, the brake system may need to bebled. To bleed the brake, use the follow-ing procedure:

NOTE: The brake system may bebled by the snowmobile owner ifqualified to do so. If the owner doesnot feel qualified, take the snowmo-bile to an authorized Arctic CatSnowmobile dealer for this service.This service is at the discretion andexpense of the snowmobile owner.

1. Remove the reservoir cover and fillthe reservoir with Arctic Catapproved brake fluid.

2. Slide a piece of flexible tubing overthe ball of the bleeder valve anddirect the other end into a container.

739-269B

! WARNINGDo not overfill the brake fluid reser-voir. Overfilling the reservoir maycause the brake system to hydrauli-cally lock. Use only Arctic Catapproved brake fluid. Never substi-tute or mix different types or gradesof brake fluid. Brake loss can result.Brake loss can result in severe injuryor even death.

! WARNINGDo not operate the snowmobile if thecompressed distance between thebrake lever and the handlebar is lessthan 2.54 cm (1 in.). Brake loss mayoccur. Brake loss can result insevere personal injury.

CAUTIONBrake fluid is highly corrosive. Donot spill brake fluid on any surfaceof the snowmobile.

! WARNINGUse only Arctic Cat approved brakefluid. Any substitute may result in aloss of brakes.

45

3. Slowly compress the brake lever andhold. Open the bleeder valve torelease the fluid and air. When thefluid stops, close the bleeder valve;then release the brake lever.

4. Repeat step 3 until the brake fluidflows free of air bubbles.

NOTE: It may be necessary to refillthe reservoir during the bleedingprocess.

5. When the brake fluid is free of all airand the brake lever feels firm whencompressed, fill the reservoir; theninstall and secure the cover. Removethe tube from the bleeder valve.

Checking/Changing Brake Pads

The condition of the brake pads must bechecked daily and changed if worn ordamaged. To check and change the brakepads, use the following procedure:

NOTE: The brake pads may bechanged by the snowmobile owner ifqualified to do so. If the owner doesnot feel qualified, take the snowmo-bile to an authorized Arctic CatSnowmobile dealer for this service.This service is at the discretion andexpense of the snowmobile owner.

NOTE: When installing new brakepads, always install them as a set.Never install just one pad or usebrake pads which have been used inanother snowmobile.

1. Measure the thickness of both brakepads. The brake pad thickness mustbe greater than 5.0 mm (0.20 in.). Ifthe brake pad thickness is less thanspecified, replacement of both padsis necessary.

0739-269

2. Remove the pin/hairpin clip secur-ing the brake pads to the caliperassembly.

3. Remove the brake fluid reservoircover; then remove most of thebrake fluid from the reservoir. Installthe cover.

NOTE: The above procedure willallow room for the fluid from the cali-per when the pistons are pushedinto the caliper for installing newbrake pads. Replacing the cover willprevent fluid spillage.

4. Using a pair of pliers, pull one brakepad out of the caliper assembly.

NOTE: Changing one pad at a timewill prevent one piston from pushingout the other piston from the caliper.

5. Using a flat-blade tool, slowly andcarefully push the piston into thecaliper.

6. Position the new brake pads into thecaliper.

7. Repeat steps 4-6 for the other pad;then secure the pads with the pin/hairpin clip.

8. Remove the reservoir cover andremove the remaining fluid; then fillthe reservoir with fresh fluid andinstall the cover.

9. Pump the brake lever to ensure cor-rect positioning of the brake pads;then release.

10. Remove the reservoir cover and fillthe reservoir to the proper level withfresh brake fluid; then install thecover.

NOTE: When new brake pads areinstalled, a “burnishing” process isrequired. Drive the snowmobileslowly and compress the brake leverseveral times until the pads just startto warm up; then allow them to cooldown. This procedure stabilizes thepad material and extends the life ofthe pads.

46

Drive BeltThe drive belt transfers power from thedrive clutch to the driven pulley. If thebelt is worn, cracked, or stretched, maxi-mum power will not be transmitted andthe belt could also fail and therefore mustbe replaced. Periodic checks (at leastonce a month under normal usage) of twodrive belt specifications are essential.

1. Measure the outside circumferenceof the drive belt. The belt should bewithin the recommended range incircumference.

2. Measure the outside width of thedrive belt. The belt should be withinthe recommended range in width.

3. Check the belt for cracking, fraying,etc.

If any of the specifications or conditionsare unsatisfactory, replace the drive belt.

NOTE: Drive belts should be pur-chased from an authorized ArcticCat Snowmobile dealer, as Arctic Catdrive belts are made to exact specifi-cations and of quality material. Beltsmade by other manufacturers maynot be of the same specifications orquality and, therefore, usage couldresult in poor performance and pre-mature belt failure.

NOTE: Before starting the snowmo-bile in extremely cold temperatures,the drive belt should be removed andwarmed up to room temperature.Once the drive belt is at room temper-ature, install the drive belt.

Also, new drive belts have a break-inperiod of approximately 25 miles. Afterinstalling a new drive belt, drive thesnowmobile for 25 miles at 3/4 throttle orless. By revving the engine up and down(but not exceeding 60 mph), the exposedcord on the side of a new belt will beworn down.This will allow the drive beltto gain its optimum flexibility and willextend drive belt life.

Checking/Adjusting Drive Belt Deflection

0743-319

The drive belt must have the proper fit inthe drive clutch and driven pulley. Tocheck for proper drive belt fit, use thefollowing procedure.

1. Place a straightedge on the top of thedrive belt. The straightedge shouldreach from the drive clutch to the topof the driven pulley.

NOTE: Make sure the drive belt isall the way out in the driven pulleybefore checking drive belt fit.

2. Using a stiff ruler centered betweenthe drive clutch and driven pulley,push down on the drive belt justenough to remove all slack and notethe amount of deflection. The deflec-tion should be within the range of28.5-31.8 mm (1 1/8-1 1/4 in.).

3. To correct drive belt deflection,remove the sheave adjuster from thepulley, remove or add shim washersto the adjuster, and install theadjuster.

NOTE: Adding shim washers willdecrease belt deflection and remov-ing shim washers will increase beltdeflection. Available shim washersfrom Arctic Cat are p/n 0648-714(0.090 in.) - one included in the toolkit, p/n 0648-715 (0.030 in.), and p/n0648-716 (0.060 in.).

NOTE: Removing/adding shimwashers may be done by the snow-mobile owner if qualified to do so. Ifthe owner does not feel qualified,take the snowmobile to an autho-rized Arctic Cat Snowmobile dealerfor this service. This service is at thediscretion and expense of the snow-mobile owner.

CAUTIONNever run the engine with the drivebelt removed. Excessive revving of theengine could result in serious enginedamage and drive clutch failure.

Track TensionTrack tension is directly related to the over-all performance of the snowmobile. If thetrack is too loose, it may slap against thetunnel causing wear or it may “ratchet” onthe track drive sprockets. If extremelyloose, the idler wheels may climb over thetrack lugs forcing the track against the tun-nel causing the track to “lock.” Arctic Catrecommends that the track tension bechecked daily during the first 300 miles ofoperation and once a week thereafter andadjusted according to need. The track willstretch and take a “set” during break-in.Track deflection must be maintained withinthe recommended range.

Checking Track Tension

1. Remove excess ice and snow buildupfrom the track, track drive sprockets,and the inside of the skid frame.

2. Elevate the snowmobile on ashielded safety stand high enough touse a spring scale.

3. At mid-point of the track (on thebottom side), hook a spring scalearound a track clip; then pull downon the scale to the recommendedpressure. Measure the deflection(distance) between the bottom of thewear strip and the inside surface ofthe track clip. Compare the measure-ment with the chart.

0743-188

0743-191

Adjusting Track Tension

NOTE: To ensure proper track ten-sion adjustment, perform all adjust-ments on both sides of thesnowmobile.

1. Loosen the rear idler wheel adjust-ing bolt jam nuts.

739-636B

NOTE: On the Bearcat XT models,the rear axle cap screws must alsobe loosened.

743-323A

! WARNINGTrack tension must be properlymaintained. Personal injury couldresult if a track is allowed to becomeexcessively loose.

! WARNINGDO NOT attempt to check or adjusttrack tension with engine running.Turn ignition key to the OFF position.Personal injury could result fromcontact with a rotating track.

2. If the deflection (distance betweenthe bottom of the wear strip and theinside of the track) exceeds specifi-cations, tighten the adjusting bolts totake up excessive slack in the track.

3. If the distance between the bottom ofthe wear strip and the inside surfaceof the track is less than specified,loosen the adjusting bolts to increasethe slack in the track.

4. Check track alignment (see TrackAlignment sub-section in this section).

5. When proper track tension isobtained, tighten the adjusting boltjam nuts against the axle housings.

NOTE: On the Bearcat XT models,tighten the rear axle cap screws to20 ft-lb.

NOTE: Since track tension andtrack alignment are interrelated,always check both even if only oneadjustment seems necessary.

Track AlignmentProper track alignment is obtained whenthe rear idler wheels are equal distancefrom the inner track drive lugs. Excessivewear to the idler wheels, drive lugs, andtrack will occur if the track is improperlyaligned. Arctic Cat recommends that thetrack alignment be checked once a weekor whenever the track tension is adjusted.

Checking Track Alignment

1. Remove excess ice and snow buildupfrom the track, track drive sprockets,and the inside of the skid frame.

2. Position the tips of the skis against awall; then using a shielded safetystand, raise the rear of the snowmo-bile off the floor making sure thetrack is free to rotate.

3. Start the engine and accelerateslightly. Use only enough throttle toturn the track several revolutions.SHUT ENGINE OFF.

NOTE: Allow the track to coast to astop. DO NOT apply the brakebecause it could produce an inaccu-rate alignment condition.

4. When the track stops rotating, checkthe relationship of the rear idlerwheels and the inner track drive lugs.If the rear idler wheels are centeredbetween the inner track drive lugs, noadjustment is necessary.

725-070A

5. If the idler wheels are not centeredbetween the inner track drive lugs,an adjustment is necessary.

! WARNINGIf jam nuts are not tightened prop-erly, the adjusting bolts could loosencausing the track to becomeextremely loose and, under someoperating conditions, allow the idlerwheels to climb over the track lugsforcing the track against the tunnelcausing the track to “lock.” If a track“locks” during operation, severe per-sonal injury could result.

! WARNINGMake sure the ignition key is in theOFF position and the track is notrotating before checking or adjustingtrack alignment. Personal injurycould result if contact is made with arotating track.

! WARNINGThe tips of the skis must be posi-tioned against a wall or similarobject.

Adjusting Track Alignment

1. On the side of the track which has theinner track drive lugs closer to therear idler wheel, loosen the adjustingbolt jam nut; then rotate the adjustingbolt clockwise 1 to 1 1/2 turns.

739-636B

NOTE: On the Bearcat XT models,the rear axle cap screws must alsobe loosened.

743-323A

2. Check track alignment and continueadjustment until proper alignment isobtained.

NOTE: Make sure correct tracktension is maintained after adjust-ing track alignment (see Track Ten-sion sub-section in this section).

3. After proper track alignment isobtained, tighten the adjusting boltjam nut against the axle housing.

NOTE: On the Bearcat XT models,tighten the rear axle cap screws to20 ft-lb.

4. Field test the track under actual con-ditions.

5. After the field test, check the align-ment of the track. If additional adjust-ment is necessary, repeat AdjustingTrack Alignment procedure.

SuspensionThe suspension should be adjusted forthe operational needs and riding prefer-ence of the operator.

The front shock springs determine theamount of ski pressure and the reactionof the front suspension to rough terrain.The amount of ski pressure can also bechanged by adjusting the length of theskid frame front arm limiter straps.

The rear springs influence the load carry-ing capability of the snowmobile andshould be adjusted for the weight and rid-ing preference of the operator.

Adjusting Front (Ski) Shock Springs

NOTE: On the Bearcat 570/T570models, the front (ski) shock springsare not adjustable.

The front (ski) shock springs are individ-ually adjustable for the terrain conditionsand driving style of the operator. Thespring adjuster/adjuster nut has been setat the factory so the correct amount ofthreads are exposed between the adjuster/nut and the threaded shock housing/bodyas an initial setting. Additional ski pres-sure can be obtained by tightening thespring tension; ski pressure can bedecreased by relaxing spring tension.

NOTE: Equal adjustments shouldbe maintained on both sides of thesnowmobile.

On the Bearcat XT models to adjustspring tension, rotate the entire spring inwhichever direction is desired. If afteradjusting spring tension you note thesnowmobile front end wants to pitch,relax the spring tension on the side that ispitching. If both sides are pitching, relaxthe spring tension on both sides.

NOTE: The spring adjuster willnormally rotate with the spring.

! WARNINGIf a jam nut is not tightened properly,the adjusting bolt could loosen caus-ing the track to become dangerouslyloose.

51

734-501B

On the TZ1 LXR models to adjust springtension, loosen the adjuster nut lockingcollar (B) from the adjuster nut (A); thenusing the Spring Adjuster Tool from thetool kit, rotate the adjuster nut in which-ever direction is desired. Tighten thelocking collar against the adjuster nut.

Adjusting Skid Frame Front Arm (Bearcat XT Models)

On these models, the skid frame front armshock spring tension and the limiter strapsare adjustable. However, Arctic Cat rec-ommends that the shock spring be main-tained at the factory preset of 1/8-1/4 in.preload. Tightening the skid frame frontarm shock spring may cause improper bal-ance and may ruin the handling features ofthe snowmobile.

The length adjustment of the front armlimiter straps determines the weight dis-tribution between the front of the skidframe and the skis. Tightening the limiterstrap (shortening the strap) will pull upon the front of the skid frame and willincrease ski pressure. Loosening the lim-iter strap (lengthening the strap) lowersthe front of the skid frame and decreasesski pressure.

When customizing the amount of skipressure, be sure to adjust both strapsequally and do not over-adjust the limiterstraps to adversely affect steering andoperator control of the snowmobile.Some experimentation may be requireduntil the proper adjustment for the opera-tor’s individual style is obtained.

NOTE: If the limiter straps areadjusted, it is highly recommendedthat at least a minimum of 1/8 in. pre-load on the shock spring be main-tained.

Adjusting Rear Spring Pre-Load

Proper adjustment of rear spring pre-loadis necessary to get the most desirableride. The chart is designed to help in set-ting up rear spring pre-load; however,riding style is the single greatest factor indetermining rear spring requirements.

NOTE: These cam position set-tings are suggestions only. Personalriding style will greatly influencecam position settings. Spend time todetermine setting preferences.

Rear spring pre-load adjustment isaccomplished by rotating the adjustingcams. Position 3 provides the stiffestride, and position 1 is for the light driveror slow-speed trail riding. Position 2 isfor the average operator under normalconditions. Always rotate the cam fromthe lighter position to the heavier posi-tion.

! WARNINGDo not adjust the front arm limiterstraps to a point at which steeringand operator control of the snowmo-bile are adversely affected.

Rider Weight (lb) Cam Position

Up to 180 1

180-240 2

CAUTIONNever force the adjustment camsfrom the low position to the highposition. Cam damage may occur.

52

741-450A

To rotate an adjusting cam, use the sparkplug wrench from the tool kit. Rotate thewrench until the cam is in the desiredposition. To stiffen the ride, rotate the camso as to raise the spring end. Make theappropriate adjustment on the other cam.

Articulating Skid Frame (Bearcat XT Models)

The rear articulating portion of the skid framehas two skid frame adjusters which controlthe amount of travel in the rear suspension.

These two adjusters have been pre-set atthe factory and should require no furtheradjustment.

If adjustment is ever required, rotate thetwo adjusters equally to permit 12.5-25mm (1/2-1 in.) travel of the articulatingportion of the suspension.

0743-323

NOTE: Tightening the adjusterswill stiffen the articulating skid frametravel; loosening the adjusters willsoften the travel.

Overload Springs

Some models have overload springs builtinto the rear suspension. When either carry-ing a heavy load or riding 2-up, the over-load springs should be engaged by rotatingthe spring tension blocks to the UP posi-tion. The spring tension blocks lock in anover-center position when engaged.

NOTE: Arctic Cat recommendsthat the overload springs beengaged whenever a load on thesnowmobile (operator/passenger/cargo) exceeds 136 kg (300 lb).

To either engage or disengage the springtension blocks, use a spark plug socketand a screwdriver to adjust the springblock to the desired position. Make sureboth spring blocks are in the same posi-tion (either engaged or disengaged).

7. Adjust the headlight using theadjustment knobs until correct aim isobtained. Shut the engine off; thendisengage the brake lever lock.

Ski Wear BarsThe ski wear bar is a replaceable barattached to the underside of the ski. Thepurpose of the wear bar is to assist in turn-ing the snowmobile, to minimize ski wear,and to maintain good steering control. If thesnowmobile is operated primarily in deepsnow, ski wear bar wear will be minimal;however, if the snowmobile is operated onterrain where the snow cover is minimal,the ski wear bar will wear faster. To main-tain positive steering characteristics, ArcticCat recommends that the ski wear bars bechecked before each use and replaced ifworn beyond 1/2 of the original diameter.Ski wear bars are available from an autho-rized Arctic Cat Snowmobile dealer.

Removing Ski Wear Bars

NOTE: Determine which type ofwear bar is being replaced andremove and install accordingly.

1. Remove ice and snow buildup fromthe ski.

2. Using a suitable safety stand or lift,elevate the front of the snowmobile.

3. Remove the lock nuts securing thewear bar to the ski.

! WARNINGDo not operate the snowmobileunless headlight beam is adjustedproperly. An incorrectly adjustedbeam will not provide the operatorthe optimum amount of light.

! WARNINGOperating the snowmobile withexcessively worn ski wear bars mayresult in a loss of steering control.

56

0743-185

4. Remove the wear bar from the ski.

Installing Ski Wear Bars

1. Move the wear bar into position onthe bottom of the ski.

NOTE: If installing a double-offsetwear bar for normal steering capabil-ities, the carbide edge should bedirected to the inside of the ski.

2. Align the wear bar studs with theholes in the ski; then install the locknuts. Tighten to 11-15 ft-lb.

Adjusting Ski Stance (Bearcat Models)NOTE: Local laws and/or regula-tions as to maximum width of the skistance on these snowmobiles maybe applicable. Always comply withthe maximum width laws and/or reg-ulations when adjusting ski stance.

NOTE: Ski stance can be increased/decreased by 6.3 cm (2.5 in.).

1. Place the front of the snowmobile ona support stand.

2. Remove the cotter pin; then removethe slotted nut and cap screw secur-ing the ski assembly to the spindle.Remove the ski. Account for therubber damper, inserts, and washers.

3. To increase ski stance, place both skistance spacers to the outside of thespindle.

4. To decrease ski stance, place bothski stance spacers to the inside of thespindle.

5. Apply an all-temperature grease to thenon-threaded portion of the capscrew; then slide the cap screwthrough the ski accounting for the rub-ber damper, inserts, and washers.

NOTE: Install the cap screw so theslotted nut will be located to theinside of the ski.

6. Apply red Loctite #271 to thethreads of the cap screw; thentighten the nut to 45 ft-lb.

7. Place the cotter pin into the ski capscrew and spread the pin.

8. Repeat procedure for the other ski.

Rail Wear StripsArctic Cat recommends that the wearstrips be checked weekly and replaced asnecessary. Measure the wear strips at 25.4cm (10 in.) intervals. Wear strips must be10.7 mm (0.42 in.) thick or thicker.

If wear strip measurements are less thanspecified, replacement of both wear stripsis necessary to prevent premature trackclip wear and possible track damage.Take the snowmobile to an authorizedArctic Cat Snowmobile dealer for thisservice. This service is at the discretionand expense of the snowmobile owner.

Each time a new set of wear strips areinstalled, they should be tempered. Tem-per the wear strips by driving the snow-mobile for approximately a mile on ahard pack trail; then immediately driveinto deep snow and allow the wear stripsto cool. Repeat the procedure (warmingup the wear strips; then cooling themdown) two or three times.

NOTE: The rail wear strips will wearrapidly if the snowmobile is operatedon terrain on which the snow cover isminimal. Loose snow is required tocool and lubricate the wear strips andprevent accelerated wear.

Performance TipsOperating a high performance snowmo-bile requires a special attention that is notrequired by a low performance snowmo-bile. Often, a minor adjustment willresult in a large increase in performance.This section is intended to highlightminor conditions that adversely affectperformance and the adjustments neededto correct them. Be sure, however, tothoroughly read and understand thisentire manual especially the section onspark plugs, track tension and alignment,and suspension.

DRIVE BELT — This link between theengine and drive train is often the mostneglected component. The drive belt musthave the proper fit in the drive clutch anddriven pulley. Proper fit is when the topsurface of the drive belt is flush with thetop or up to 1/16 in. higher than the drivenpulley sheaves (with the sheaves fullyclosed). If drive belt deflection is abovespecification, the snowmobile will bog andlack power at engagement and will have aslower maximum speed. For good perfor-mance, proper belt deflection is critical. Tocorrect this condition, first determine if thedrive belt is within specifications (seeDrive Belt sub-section) and replace ifworn or too long. Always run the drivebelt in the same direction. Installing thedrive belt so the part number can be readwill ensure that the drive belt is alwaysrun the same direction.

DRIVE BELT DEFLECTION — Drivebelt length, condition, and deflection areall important for peak performance. Tocheck and adjust drive belt deflection,remove the belt guard; then use the fol-lowing procedure.

NOTE: It may be necessary toremove a shim washer from betweenthe driven pulley sheaves to allow thedriven pulley to close tighter. Addingshim washers will decrease beltdeflection and removing shim wash-ers will increase belt deflection. Avail-able shim washers from Arctic Cat arep/n 0648-714 (0.090 in.) - one includedin the tool kit, p/n 0648-715 (0.030 in.),and p/n 0648-716 (0.060 in.).

NOTE: Removing/adding shimwashers may be done by the snow-mobile owner if qualified to do so. Ifthe owner does not feel qualified,take the snowmobile to an autho-rized Arctic Cat Snowmobile dealerfor this service. This service is at thediscretion and expense of the snow-mobile owner.

1. Turn the engine off; then open theaccess panel.

2. Make sure the drive belt is sitting atthe top of the driven pulley sheaves.

3. Place a straightedge on top of thedrive belt. The straightedge shouldreach from the driven clutch to thetop of the driven pulley.

4. Using a stiff ruler centered betweenthe drive clutch and driven pulley,push down on the drive belt justenough to remove all slack. Note theamount of deflection on the ruler atthe bottom of the straightedge. Thedeflection should be at 1 1/4 in.

0743-319

NOTE: Push down on the belt withthe ruler only until the bottom of thebelt flexes upward; then read theamount of deflection.

5. To correct drive belt deflection,remove the sheave adjuster from thepulley, remove or add shim washersto the adjuster, and install theadjuster.

NOTE: Adding shim washers willdecrease belt deflection; removingshim washers will increase beltdeflection.

6. Install the belt guard; then close theaccess panel.

58

DRIVE CLUTCH AND DRIVENPULLEY — Keeping the drive clutchand driven pulley clean should be the pri-mary consideration of the operator. Thedrive clutch and driven pulley can becleaned of any drive belt accumulationusing compressed air. The sheaves can becleaned using a clean cloth and parts-cleaning solvent.

DRIVE CLUTCH/DRIVEN PULLEYOFFSET — If premature drive belt wearis experienced or if the drive belt turnsover, offset must be checked. Also, offsetmust be checked whenever either thedrive clutch or driven pulley is serviced.

NOTE: For checking offset, it isnecessary to use Clutch AlignmentBar (p/n 0644-496). This special toolcan be purchased from an autho-rized Arctic Cat snowmobile dealer.

To check offset, use the following proce-dure.

1. Open the left-side access panel; thenremove the belt guard.

2. Install the clutch alignment barbetween the drive clutch sheaves.

3. Allow the bar to rest on the driveclutch shaft and against the outsideedge of the driven pulley stationarysheave.

NOTE: The alignment bar mustextend beyond the front edge of thedrive clutch.

4. With the bar against the outside edgeof the driven pulley stationarysheave at points A and B, the barshould just clear the inside edge ofthe stationary sheave of the driveclutch and rest on the stationaryshaft at point C with a maximum0.060 in. clearance at point C. Atthis point, measurement betweenpoints A and C should be 1.507 in.(with a maximum 0.060 in. clear-ance). If the bar either will not clearthe inside edge or is more than thespecified amount, the offset must becorrected.

0745-177

NOTE: If the offset is out of speci-fication, take the snowmobile to anauthorized Arctic Cat Snowmobiledealer for drive system evaluationand/or servicing. This service is atthe discretion and expense of thesnowmobile owner.

DRIVE CLUTCH/DRIVEN PULLEYPARALLELISM — If premature drivebelt wear is experienced or if the drivebelt turns over, parallelism must bechecked. Also, parallelism must bechecked whenever either the drive clutchor driven pulley is serviced.

NOTE: For checking parallelism, itis necessary to use Clutch Align-ment Bar (p/n 0644-509). This specialtool can be purchased from anauthorized Arctic Cat Snowmobiledealer.

To check parallelism, use the followingprocedure.

1. Remove the drive belt; then open thedriven sheaves and place clutchalignment bar between the sheaves.Release the sheaves.

2. Check the parallelism of the driveclutch/driven pulley using the paral-lelism bar and reference points Xand Y with the parallelism barbetween the driven sheaves. Using acaliper or a machinist’s scale, mea-sure X and Y from the back side ofthe parallelism bar to the back sideof the drive clutch sheave. Measure-ment Y must be 0.060 in. ± 0.020 in.more than measurement X, but Ymust not exceed measurement X bymore than 0.100 in.

59

0744-609

3. If parallelism is not within specifica-tions, the parallelism must be cor-rected by first loosening all theengine mounting bolts (left side,front, and right top rear). Then, prythe front of the engine towards theMAG-side of the engine compart-ment. Next tighten the left-sidemounting bolts followed by the frontand right-top rear bolts. Re-checkthe parallelism. If still out of specifi-cation, repeat correction procedure.

CARBURETOR MAIN JETS(Bearcat 570/T570 Model) — Propercarburetion is absolutely necessary toobtain peak performance. Since ambienttemperature and operating altitude bothaffect the main jet size needed for opti-mum engine performance, the main jetsMUST be changed whenever the temper-ature changes 20° F or whenever operat-ing altitude varies by more than 1000feet. The Carburetor Jet Chart on the beltguard of the snowmobile identifies theproper main jets to use under all operat-ing temperatures and altitudes. Followthe Carburetor Jet Chart carefully toobtain peak engine performance andavoid engine damage.

GASOLINE — It is not necessary toexceed the recommended 87 octane gaso-line. Using a higher octane gasoline willnot increase overall performance; how-ever, the TZ1 Turbo model will detectlower octane gasoline and reducedengine performance will result. It is rec-ommended that 91 octane (minimum)gasoline be used in the TZ1 Turbo mod-els.

60

Preparation for StoragePrior to storing the snowmobile, it must beproperly serviced to prevent corrosion andcomponent deterioration. An authorizedArctic Cat Snowmobile dealer should per-form this service; however, the owner/operator can perform this service if desired.This service is at the discretion andexpense of the snowmobile owner. To pre-pare the snowmobile for storage, Arctic Catrecommends the following procedure:

Warranty Procedure/Owner Responsibility

At the time of sale, an Owner Registration form is to be completed by the sellingdealer and consumer. The receipt of the registration form by Arctic Cat is a condi-tion precedent to warranty coverage. It is the selling dealer’s responsibility to retainand/or submit the appropriate copies of the form to the appropriate place(s) to initi-ate warranty coverage.

The dealer will furnish to the consumer a signed copy of the form which must bepresented to the dealer when requesting warranty service. The registration form isthe consumer’s proof of ownership and warranty eligibility. The form is usedby the dealer to validate the warranty claim. Retain your copy of the form andkeep it in a safe place.

When warranty repair is suspected, the snowmobile should be taken to the sellingdealer, who has the primary responsibility to perform warranty repairs. Subject tothe limitations set forth in the Limited Warranty, in the event the selling dealer hasceased to do business, you have moved, or you are in a location away from yourselling dealer, warranty may be performed by any authorized Arctic Cat Snowmo-bile dealer.

The authorized Arctic Cat Snowmobile dealer will examine the snowmobile or partto determine if, in his opinion, a warrantable condition exists. If a warrantable con-dition appears to exist, the dealer will repair or replace, at Arctic Cat’s option, freeof charge, including any related labor costs, all parts that are found to be warrant-able and any other parts which the warrantable part caused to be damaged. You, theconsumer, will then be asked to sign a warranty form to ensure Arctic Cat that thewarranty work was actually performed.

It is the consumer’s responsibility to maintain and service the snowmobile in accor-dance with Arctic Cat’s recommendations in the Operator’s Manual. To protectyourself and your snowmobile, follow all safety and service tips. Arctic Cat willNOT warrant repairs required as a result of not performing standard operatormaintenance, storage procedures, and service as outlined in the Operator’sManual.
