Transmission Coupler Drive Belt Adjustment
1. Park mower on a level surface. Make sure engine is
OFF. Remove high tension lead from the spark plug.
2. To check transmission coupler drive belt tension:
A. Remove cap screw, flat washer, belt cover (Fig.
11), spacer (under cover), and flange nut (Fig. 13) to
expose drive belt.
B. Check belt tension by depressing belt at mid span
between the pulleys with 3 to 5 lbs (13 to 22 N) of
force (Fig. 12). The belt should deflect 1/4 inch (6
mm).
C. If deflection is correct, continue operation. If
deflection is incorrect, proceed to next step.
3. To adjust drive belt tension:
A. Loosen the two bearing housing mounting nuts
(Fig. 12).
B. With a 3/8 in. drive torque wrench, pivot the bear-
ing housing from 35 to 40 in–lb (40 to 46 kg–cm) to
set belt tension (Fig. 13). Do not over tension belt.
Hold bearing housing with the torque wrench and
tighten bearing housing mounting nuts to lock adjust-
ment (Fig. 12).
C. Recheck belt tension deflection.
D. Reinstall belt cover by placing the cover with
spacer in position and securing with cap screw,
