    STEP

    1Preparation for Repair

    1) Remove Nose Cone2) Remove handpiece from air supply3) Remove Gasket {HHX4HG}

    Gasket Inspection: Examine gasket for obvious wear, tearing or disfigurement. Ifany of these conditions exist, replace.

    STEP

    2Seperate Body from Backend

    Place a strip of Emery Cloth & Leather [TSX007]around the forward edge of the largest diameterof the housing. Using your left hand, grip EmeryCloth & Leather with 6 Pliers [THR062].

    Using a 6 Adjustable Wrench [THR080], adjustwrench to match the flats and position on thebackend. Rotate in a counter clockwise directionto losen Backend from the Body.

    Using an 1/8 Punch [TMX004], apply pressureto the Main Drive Gear {LST016} while unscrew-ing the backend assemly by hand. NOTE: Apply-ing pressure to the Main Drive Gear eases theunthreading of the backend.

    After the Backend has been unthreaded, use a 1/8 Punch [TMX004] to push the Motor Assemblyand Gear Reduction Assembly completely out ofthe Body.

    Inspection of Motor Housing: Examine MotorHousing for obvious damage/dents to Housing and/or threads. Check for corrosion. If these condi-tions exist, replace.

    STEP

    3Disassembly of Backend

    Using s Small Screwdriver [THR097], remove theReserving Ring Screw {LST008} by unscrewingin a counter clockwise direction.

    Using a Dental Pick [THR066] or X-Acto Knife[THR060], remove the O-Ring {LST180} from theReversing Ring Screw. NOTE: O-Ring is a stan-dard replacement part.

    Remove the Reversing Ring by first removing theLarge O-Ring {LST182}, using a Dental Pick orX-Acto Knife. Then pull the Reversing Ringdirectly away from the Backend. Lastly, removethe two Large O-Rings {LST182} using the sametool. NOTE: The Large O-Rings are standardreplacement parts.

    Remove the Air Distributor by inserting a SmallScrewdriver through the window of the Backend{LST010} into the threaded hole. Then elevate theAir Distributor and remove by hand. NOTE: If theAir Distributor shows resistance it may be neces-sary to rotate left to right until its lose enough toelevate.

    Remove O-Ring {LST181} from the bottom of theAir Distributor using a Dental Pick or X-ActoKnife. NOTE: This O-Ring is a standard replace-ment part.

    Inspection of the Backend: Examine for obviousdamage or corrosion. If either of these conditionsexists, replacement is recommended.

    Inspection of the Reversing Ring: Examine forobvious damage or corrosion. If either conditionexists, replace,

    Inspection of the Reversing Ring Screw: Examinefor obvious damage or corrosion. Inspect allthreads for excessive wear. Replace if these condi-tions exist.

    6Remove Motor Housing, Blades & Spring

    Slowly pull Motor Housing Directly away fromthe Rotor.

    NOTE: Blades are under a spring load and willtend to pop out or fall from their location. Usecaution not to lose the blades or springs.

    Blades (set of 5) {LST017}Springs (set of 5) {LST019}

    Remove each blade from each slot, taking carenot to lose or damage springs.

    Gently remove Rotor Springs with an X-ActoKnife [THR060]. Be careful not to lose the springs.

    Inspection of Rotor Blades & Springs: CheckRotor Blades for worn grooves, breaks, chips andwear. Inspect Springs for obvious damage, replaceif needed.

    Gently tap the middle of the Sun Gear{LST002}using a 1/16 Stub Punch [THR081],completely removing the Sun Gear, Avoider, andFront Bearing Carrier.

    Remove the Bearing {LST021} from the Carrier.Place the carrier on the Disassembly Block[THR009], over a hole larger then the bearing. Re-move bearing from carrier by gently tapping thebearings inner-race, using a 1/8 Punch.

    NOTE: The bearing is a manditory replacementpart.

    Inspection of the Bearing Carrier: Inspect forgrooves or rough finish.

    Inspection of the Sun Gear Avoider: Inspect forobvious damage or disfigurement. Replace if anyof these conditions exist.

    NOTE: Check both ends of the Rotor for scoringand/or burs. If groove appears on either carrier orRotor, lap part on 600 grit wet dry sandpaper in afigure eight motion until smooth.

    To Debur Rotor: Using the Assembly Block, place600 grit wet & dry sandpaper over the hole closestin size to the Rotor Shaft. Then push the Rotor Shaftthrough the sandpaper and rotate until smooth.
