7e. Adjust the number of shims (spacers)
behind the driven pulley to achieve cor-
rect alignment. Use the three .800" (2 cm)
I.D. flat washers that are included in the
kit, if necessary.
7f. Once alignment is correct, install the
driven pulley screw with thread locking
compound such as Loctite® 262 (red),
and tighten it to 32-36 ft-lb. (43-49 N-m).
7g. Install the cooling fan on the driving pulley,
securing it with the flat washer and castle
nut. See Figure 2b.28.
Figure 2b.28
7h. Tighten the nut to a torque of 22-25 ft-lbs.
(30-34 N-m), then secure it using the cot-
ter pin.
7i. Inspect the drive belt. If it is worn to less
than 1.20" (30.5mm) across the flat back
surface of the belt, or if is shows signs of
burning or checking, replace it with a new
belt.

7k. Remove the screw that was used to
spread the sheaves of the driven pulley.
7l. Place the gear selector in neutral.
7m. Re-connect the negative battery cable.
7n. Clip a jumper wire from the eyelet on the
fuel pump ground wire to a good ground.
7o. Confirm that the drive belt area is clear,
and that no unsafe conditions will arise
from starting the engine.
7p. Start the engine briefly and confirm that
the CVT operates properly throughout the
engine RPM range, before installing the
CVT cover.
The driven pulley should not rotate when the
engine is at idle speed.
If the driven pulley does rotate at idle speed:
Re-check the spacing and alignment of the pul-
leys.
Confirm that the driving pulley is returning all the
way to rest position at idle.
