2. Loosen the idler pulley mounting nut and pivot the idler
pulley clockwise against the backside of the belt until
the desired belt tension is attained (Fig. 38).
Important Do not over tension the belt.

3. Tighten the nut to lock adjustment.
4. Install the belt cover by placing it in position.
5. While maintaining a slight gap between the cover seal
and the side plate, install each mounting bolt until the
threads engage in the insert. The gap allows visual
alignment of the bolts to the threaded inserts.
6. After all bolts are installed, tighten them until the
stand-offs inside the cover contact the side plate. Do not
overtighten.
Adjusting the Differential Belt
Check the tension by pressing the belt at mid span of the
pulleys with 4 to 6 lb. of force. The belt should deflect 1/4
in. (0.63 cm). If the deflection is incorrect, adjust the belt as
follows:
1. Remove the capscrews securing the front and rear
sections of the differential cover to the differential
housing and slide the cover sections away to expose the
belt.

Adjusting the Primary V-Belts
1. To adjust the belt tension on primary V-belts, first check
the adjustment of the traction control. Refer to
Adjusting the Traction Control, page 29. If unable to
attain the 3 to 5 lb. force required in adjusting the
traction control, proceed to next step.
2. Loosen the retainer securing the V-belt cover and pivot
the cover open.
