CVT Drive and brake system
29. Remove the top of the housing, and adjust the
bevel shaft gear shims as necessary, then re-
check.
NOTE: The back-lash in the input shaft is a func-
tion of the amount of play between the pinion
gear and the bevel gear it is driving.
Shimming a bevel gear to run nearer the pinion
shaft will reduce the back-lash.
Removing shims to allow more space between
the pinon and bevel gears will increase the
amount of back-lash.
30. Install, or add Durina
fl.oz. (.59 liters) in the housing.
31. Carefully install the top of the housing, and
install the 13 perimeter screws, leaving 2 empty
screw holes; 1 on each side of the brake spline.
NOTE: No sealant is necessary.
32. Tighten the screws to a torque of 90-135 in-lbs.
(10-15 N-m).
33. Install the detent ball, spring, and screw.
34. Tighten the detent screw to a torque of 160-200
in-lbs. (18-23 N-m).
35. Assemble the brake yoke:
35a. Apply a small amount of anti-seize com-
pound to the brake rotor splines and to the
actuator pins in the brake yoke.
CAUTION: Do not get anti-seize on the friction
surfaces of the brake
35b. Install the steel backing plate against the
pins, then place the friction pad against the
backing plate. See Figure 6.109.

35d. Install the brake yoke to the transaxle,
being careful not to let the friction pad or
backing plate fall out of place.
35e. Tighten the brake yoke screws to a torque
of 90-135 in-lbs. (10-15 N-m).
35f. Set the clearance between the pads and
rotor to .010-.015" (.25-38mm) using the
adjusting nut on the brake yoke.
See Figure 6.111.
