Drum Drive 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 mid span be-
tween the pulleys with 4 to 5 lbs (18 to 22 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 wheels if installed.
B. Remove cap screws, lock washers, and belt cov-
ers from the side plates (Fig. 4).
C. Loosen idler pulley capscrew (Fig. 5).
D. Pivot the idler pulley clockwise against the back-
side of the belt until desired belt tension is attained.
Do not over tension belt (Fig. 6).
E. Tighten cap screw to lock adjustment (Fig. 5).
Note: Make sure spacer is on the lower pulley before
the belt cover is reinstalled.
F. Reinstall belt cover by placing the cover in posi-
tion. 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 capscrews are installed,
tighten them until the stand offs inside the cover
contact the side plate. Do not overtighten (Fig. 6).
