5. To correct drive belt deflection, washers can be

removed or added between the stationary and

movable sheaves of the driven pulley.

„ NOTE: If the drive belt deflection is above speci-
fications, the snowmobile will bog and lack power
at clutch engagement. For good performance,
proper belt deflection is critical.

6. Secure the belt guard.

ACT Roller Driven Pulley 

(Jaguar Z1/Turbo Models)

REMOVING/DISASSEMBLING

1. Remove the drive belt.

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

2. On the turbo models using Drive Belt Deflection

Tool (p/n 0644-412), remove the sheave

adjuster. Account for an O-ring and shim wash-

ers.

CM076A

„ NOTE: The sheave adjuster on the turbo models
has left-hand threads.

3. Using a 9/16-in. socket and extension, remove

the cap screw securing the driven pulley to the

input/driven shaft.

4. Slide the driven pulley off the shaft.

„ NOTE: If the driven pulley is tight on the shaft,
pull the driven pulley off using the Driven Pulley
Puller (p/n 0644-469).

„ NOTE: On the turbo models after removing the
driven pulley, retrieve the cap screw and washers
from inside the pulley bore; then account for and
remove any alignment washers along with the
spacer and spacer washer. These alignment wash-
ers must be used during assembling/installing.

„ NOTE: On the Jaguar Z1 after removing the
driven pulley, account for the cap screw and wash-
ers, sheave adjuster, alignment washers, and O-
ring from outside the pulley; then from the input
shaft, remove the two 1.5 mm (0.060 in.) washers
along with any other alignment washers. These
washers must be used during assembling/install-
ing.

5. Prior to disassembling, mark the driven pulley

sheaves and torque bracket.

CM060

6. Place the driven pulley on the Driven Pulley

Compressor Tool (p/n 0644-444); then install

the compressor flange spacer and wing nut and

compress the driven pulley spring.

FS090

7. Remove the torx-head cap screws securing the

movable sheave to the pulley.

8-24

CM061

„ NOTE: To loosen the torx-head cap screws, it
may be necessary to insert a torx-bit and strike
each screw with a hammer.

8. Release the compression of the spring by

removing the wing nut; then remove the mov-

able sheave. Account for the spacer (retainer). 

 

FS093

FS094

„ NOTE: Note the location of the holes in the
spacer for assembling purposes.

9. Remove the stationary sheave; then remove the

plastic washer (spring seat) and the spacer.

CM062

10. Remove the spring; then remove the remaining

spring seats.

CM063

CM064

„ NOTE: Premature wear will result if the plastic
washer is not installed during assembling.

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 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 rollers, pins, and spring mounting

holes for cracks, damage, or wear.

7. Inspect the cover 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 specification, the

driven pulley must be replaced.

„ NOTE: The movable and stationary sheaves are
non-serviceable components.

REPLACING TORQUE BRACKET 

BEARING

1. Remove the snap ring from the bracket.

2. Using a suitable driving tool, drive the bearing

out of the bracket.

3. Install the new bearing; then secure with the

snap ring.

! 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.

! WARNING

Always wear safety glasses when using the bearing
driver.

8-26

REPLACING ROLLERS

1. Drive the spring pins out of the stationary

sheave until there is enough room to drive out

the cam roller pin.

FS101

2. Using an Allen wrench and a flat-blade screw-

driver, press the roller pin out of the stationary

sheave.

CM065

„ NOTE: Once the roller pin is exposed, it may be
necessary to use a pair of vise-grips to remove the
pin.

FS105

3. Place the new roller into position and tap the

roller pin in far enough to install the spring pin.

CM066

CM067A

4. Tap the spring pin back into place.

CM068A

ASSEMBLING/INSTALLING

1. Place the torque bracket onto the Driven Pulley

Compressor Tool (p/n 0644-444); then place the

spring and plastic washer (spring seat) into posi-

tion.

! CAUTION

Care must be taken not to damage the driven pulley
shaft.
