Adjustments
Differential Belt Adjustment
1. Park mower on a level surface. Make sure engine
is OFF. Remove high tension lead from the spark plug.
2. Check tension by depressing belt at the mid span
between pulleys with 5 to 6 lbs (22 to 27 N) of force. The
belt should deflect 1/4 inch. If deflection is incorrect, pro-
ceed to next step. If deflection is correct, continue op-
eration.
3. To adjust belt tension:
A. Remove capscrews securing the front and rear
box covers to countershaft housing. Slide covers
away from the housing to expose the belt (Fig. 2).
B. Loosen idler pulley cap screw on the engine side
of the housing (Fig. 3).
C. Pivot idler pulley clockwise against the backside
of the belt until desired belt tension is attained. Do
not over tension the belt (Fig. 2).
D. Tighten cap screw to lock adjustment (Fig. 3).
E. Reinstall box covers by placing the covers in
position. While maintaining a slight gap between the
cover seal and the side plate, install each cap screw
until the threads engage in the insert. The gap will
allow visual alignment of the cap screw to the
threaded insert. After all cap screws are installed,
tighten them until the stand offs inside the covers
contact the side plate. Do not overtighten (Fig. 2).
