LUBRICAHON

The engine is lubricated by oilmixed with the fuel. Recommendedfuel/oil ratio is 201 using regulargasoline and an approved snowmobileoil.

The Apex Reversing Transmissionshould be kept filled to level of checkplug (1—Figure 1) with AutomaticTransmission Fluid, Type "A" orequivalent. Add fluid if required, byremoving shift bracket retaining capscrew (2).

Drive chains should be lubricatedwith a dry type chain lubricant onceeach day or oftencr if necessary.Steering rack and gear should be lu-bricated at least once each season withLubriplate or equivalent, or dry gra-phite.

Front wheels when used, should beremoved and bearing:! packed period-

measured from front to rear of wheel;or %-% inch when measured to frontand rear tips of skis. Tie rod endmust be disconnected from spindle tomake the adjustment, and wheel mustbe removed if so equipped. On GT15Models, when toe-in is adjusted, steer-ing clutches must be checked as out-lined in the following paragraph.

STEERING CLUTCH ADJUST-MENT. On GT15 Models, turning frontwheels 2 to 5 degrees should releasethe clutch on inside track. Steeringclutch adjustment should be checkedand adjusted if necesary each timetoe-in is adjusted, each time drivechain is adjusted, or any other timemisadjustment is suspected.

With steering wheel carefullyturned until wheels or skis are point-ing EXACTLY straight ahead, steer-ing clutch adjusting nuts should justcontact brackets on brake rods with-out moving brake rod. Any movementof steering wheel for right or left tumshould cause adjusting nut for outsidetrack to move away from brake rodbracket. Refer to Fig. 2 and Fig. 3.

Adjust as necessary until proper con-tact is made. An operational test ofsteering clutches can be made asfollows:

Securely support rear of machinewith both tracks clear of ground orfloor. With transmission in "Forward",start and run engine at moderatespeed. When front wheels are turnedslightly (approx. 5 degrees) in eitherdirection, inside track should stopturning. Formsprag brake unit shouldnot apply when steering wheel isturned to lock position in either di-rection. Adjust by turning nut (N—Fig. 3) as required.

DRIVE CHAWS. The 1870 Trackerand Model 210 use a single primarydrive chain running from transmissionoutput shaft to secondary shaft, andtwo chains running from secondaryshaft, and two chains rimning fromsecondary shaft down to track driveaxles. Model GT15 uses two primaryand two secondary drive chains. Sug-gested free play on all chains is ap-proximately ^-inch.

Primary chain or chains can be ad-justed by removing shims from be-neath secondary shaft pillow blockmounting bolts. Shims may be added,if necessary, beneath transmissionbase and upper pillow block.

Secondary chains are adjusted byloosening the four power framemounting bolts (10—Fig. 2) and tight-ening anchor rod nut. Brake rods,steering clutch rods and shift linkagemust be readjusted if power frame ismoved.

SINGLE DISC BRAKE. 1970 modelsand later Model 210 are equippedwith a single disc brake located onsecondary drive shaft as shown inFig. 5. To adjust the brake, proceedas follows:

Disconnect brake rod and spring(3—Fig. 4) from actuating lever. Re-move cotter pin (1) and tighten ad-justing nut (2) snugly, then back offuntil disc is free. Align cotter pinhole and reinstall cotter pin (1). Ad-just brake rod yoke if necessary untilpin can be installed, then reinstall

spring (3). Brake link must be ad-justed if powerframe is moved to ad-just secondary drive chains.

NOTE: Some early models may notuse return spring (3), and yoke pinwill be retained by a cotter key.Spring assists in preventing weight ofbrake rod from partially apply brake.

MULTIPLE DISC BRAKE. On GT-15 Models, a multiple disc brake (3—Fig. 6) is a part of the FOHMSPRAGcontrol unit (CB). Individual controlsare used for each track.

The clutch-brake unit does not re-quire internal adjustment but linkageadjustment is critical. To adjust thelinkage, refer to Fig. 3 and proceedas follows:

Disconnect brake rod (5RL) at for-ward (pedal) end. Back off nut (N)until it is free of actuating bracketon brake rod. Turn adjusting yoke (Y)as required until brake rod can justbe reconnected to pedal shaft withoutmoving actuator arm (A). Readjuststeering clutch links as previouslyoutlined after brake linkage is prop-erly adjusted. Brake linkage must beadjusted if power frame is moved toadjust secondary drive chains.

SmFT LEVER LINK. Shift leverlink may need to be adjusted if powerframe is moved to adjust secondarydrive chains, or if hand lever rideseither end of slot in shift plate. Referto Fig. 8. Disconnect the rod at trans-mission end and turn adjustable endin or out as required until shift action

-is satisfactory.TRACK. To adjust track tension,

raise and block rear of machine toallow access to inside adjusting bolts.With rear of machine raised, trackshould just touch center bogie wheels

NOTE: Whenever track tension hasbeen adjusted, alignment MUST bechecked as outlined in TRACK SER-VICE Section of this manual.

OVERHAUL

Ski support attaches to front wheelspindle as shown in Inset, Fig. 10.Steering post, support and both tierods are removed as a unit after re-moving steering wheel, shaft and rack,then disconnecting tie rods at outerends. Silicone Rubber Sealant shouldbe used when reinstalling support orany other parts attached to waterproofbody. Front tire pressure should be 4psi.

Engine and other units are access-ible for minor service or inspectionafter removing rear compartmentcover. Upper body half may be com-pletely removed or tipped up for ma-jor service. Wiring harness, controlcables and allied parts must be re-

Usea 3/16-inch drill to drill out poprivets, leaving front row if body isbeing tipped, or until wiring is dis-connected if top is being removed.When reinstalling rubber bumper, notethat back portion is wider than front.
