Installing

„ NOTE: Before installing the drive clutch, be sure
to wipe both the crankshaft taper and clutch
mounting taper clean using a clean towel.

1. Place the drive clutch into position on the crank-

shaft and secure with the cap screw and lock

washer. Tighten to specifications.

„ NOTE: To aid in proper tightening of the drive
clutch cap screw, apply oil to the threads of the
cap screw prior to installing.

CM113

2. Check alignment between the drive clutch and

driven pulley (see appropriate Drive Clutch/

Driven Pulley in this section).

AO374

3. Install the drive belt. Check drive belt deflection

(see appropriate Drive Clutch/Driven Pulley in

this section). Secure the belt guard and install

the plug in the belly pan.

„ NOTE: For installing drive belt on models with
the ACT Roller Driven Pulley, see Removing/
Installing Drive Belt (ACT Roller Driven Pulley) in
this section.

4. Either test drive the snowmobile or run the

engine for five minutes; then verify the drive

clutch cap screw torque specification.

! CAUTION

Care must be taken when installing the cover not to
damage the bushing.

! CAUTION

When installing the drive clutch, do not tighten the
clutch bolt with any kind of impact tool. Tighten
clutch bolt using a hand torque wrench only. Failure
to do so could result in stationary sheave damage.

! WARNING

Never operate the engine without the belt guard/side
panel secured.

REMOVING

1. Open the hood; then open the belt guard.

2. Remove the drive belt.

3. Remove the cap screw and washer securing the

driven pulley; then account for and note the

position of any alignment washers.

SC013D

4. Slide the driven pulley off the driven shaft; then

remove pulley from the engine compartment.

„ NOTE: If the driven pulley is tight on the shaft,
pull the driven pulley off using the Driven Pulley
Puller (p/n 0744-023).

5. Remove the key, alignment washers, and stub

shaft from the driven shaft.

DISASSEMBLING

1. Scribe a line across all driven pulley compo-

nents to ensure correct assembly and pulley bal-

ance.

SC001D

2. Place the driven pulley on a work fixture so the

roller plate is directed upward.

SC002D

„ NOTE: To aid in driven pulley servicing, use a
roll of duct tape as a work fixture. The work fixture
will increase the stability of the pulley during the
repair procedure.

3. Remove the three lock nuts securing the roller

plate; then carefully slide the plate off the sta-

tionary shaft allowing the spring to release ten-

sion.

SC003D

4. Remove the spring.

! WARNING

The roller plate is under spring pressure. Care must
be taken when removing the lock nuts to prevent the
plate from ejecting prematurely.

5. Slide the movable sheave off the stationary

shaft; then remove any thrust washers located

between the sheaves noting the position of

washers for assembling purposes.

B459D

B460

6. Remove the three socket head screws and lock

washers securing the torque bracket (cam) to the

stationary sheave; then remove torque bracket.

AI062

7. Place the roller plate on a work fixture (roll of

duct tape, etc.).

SC004D

8. Using a 1/8-in. punch, remove the spring pin

securing the roller, roller pin, and thrust washer

to the plate.

SC005D

9. Using the Roller Pin Removal Tool (p/n 0644-

276) from inside the plate, drive the roller pin

out of the plate. Account for the pin, thrust

washer, and roller.

CLEANING AND INSPECTING

„ NOTE: Whenever a part is worn excessively,
cracked, or damaged in any way, replacement is
necessary.

1. Using parts-cleaning solvent, wash grease, drive

belt dust, and foreign matter off all components.

2. Inspect the rollers for damage, cracks, or wear.

3. Inspect the sheaves for any gouges, cracks, or

other damage. Also, inspect threaded areas of

sheaves for damaged or stripped threads.

4. Inspect the torque bracket (cam) for cracks or

damage. The ramp portions of the bracket and

caps must be free of gouges and damage. Minor

scratches may be repaired using #320 grit wet-

or-dry sandpaper.

B465

5. Inspect spring for distortion, crystallization, or

breaks.

6. Inspect the roller plate, rollers, pins, and spring

mounting holes for cracks, damage, or wear.

7. Inspect the roller plate and movable sheave

bearings for wear. For each respective bearing,

measure the outside diameter of the shaft and

the inside diameter of the bearing. Compare the

readings. Clearance between the shaft and the

respective bearing must not exceed 0.5 mm

(0.020 in.). If the clearance exceeds the specifi-

cation, the bearing must be replaced.

B466D

B467

! CAUTION

Do not use steel wool or a wire brush to clean driven
pulley components. A wire brush or steel wool will
cause the sheaves to be gouged (thus, the drive belt
may not slide properly between sheaves). Decreased
performance and possible accelerated drive belt
wear will result.
