CONTINUOUSLY VARIABLE TRANSMISSION (CVT)
Read all of Section B and this section before attempting any procedure. Pay particular attention to Notices, Cautions, Warnings and Dangers.
To
prevent burns and other possible injuries:
Disable the electrical system before attempting
to remove the drive belt to prevent the engine
from inadvertently starting.
Be sure that the engine and exhaust compo-
nents have cooled before attempting any ser-
vice.
Do not allow fingers to become trapped
between the belt and clutch sheave.
Use only sockets designed for use with an
impact
wrench. Never use
a
socket intended
for use with hand tools.
Remove the drive belt (1). See 'Removing the Drive Belt'
on page E-4. Remove the starter/generator belt per
ENGINE section.
Remove the clutch bolt (2), lock washer (3) and pilot
washer (4) (Ref Fig. 2 on page E-2). Insert a greased
clutch puller and tighten (clockwise) using an impact
wrench which will remove the clutch from the engine
crankshaft.
In some extreme cases, the clutch may not separate from the
crankshaft. Remove the clutch puller and fill the cavity with
grease. Replace the clutch puller and tighten it with the impact
wrench. The combined mechanical and hydraulic effect will
remove the clutch. Remove all excess grease.
Drive Clutch Installation
To prevent damage to the clutch, be sure to remove all
grease from the body of the clutch since grease pene-
trating the seal may cause premature clutch failure.
Do not install the bolt with an impact wrench.
Clean both the engine crankshaft and the drive clutch
bore. Slide the clutch onto the engine crankshaft and
rotate the clutch while lightly pushing the moveable
sheave in and out several times to seat the clutch with
the tapered crankshaft (Ref Fig. 2 on page E-2).
Install the lock washer (3) and the large pilot washer (4)
onto the clutch bolt (2).
Apply thread locking adhesive to the threads of the
clutch bolt and install and tighten to 40 ft. lbs. (55 Nm)
torque.

Remove the drive belt (1) (Refer to 'Removing The Drive
Belt' procedure elsewhere in this section).
Remove the clutch bolt (5), the lock washer (6) and the
pilot washer (7) and slide the clutch from the rear axle
input shaft.
Driven Clutch Repair
Parts must be reassembled in same position
as their original
position. Mark all components to facilitate accurate reassem-
bly.
Some minor field repairs may be made to the driven
clutch. Remove the retaining ring (8) and remove the
torque ramp (Ref Fig. 2 on page E-2). Remove the
spring (10) and the moveable sheave (11).
Inspect the shaft for signs of wear and inspect the bush-
ings for signs of deterioration. If there is wear to the
point of causing vibration, the clutch must be replaced.
Driven Clutch Assembly
Assemble the moveable sheave (11) to the fixed sheave
(12) and insert the spring (10) in the pilot hole in the
moveable sheave (Ref Fig. 2 on page E-2). Insert the
ther end of the spring in the torque ramp (9) and rotate
the ramp counterclockwise 140°
before engaging the
splines and inserting the retaining ring (8).
Driven Clutch Installation
Coat the rear axle input shaft with a light coating of anti-
seize compound and slide the clutch onto the shaft (Ref
Fig. 2 on page E-2). Install the lock washer (6) and pilot
washer (7) to the clutch bolt (5) and apply thread locking
