Section 5: Maintenance
WARNING Before inspecting, cleaning or servicing the unit, shut off engine, wait for all parts to come to a
complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key on elec-
tric start models. Failure to follow these instructions can result in serious personal injury or
property damage.
REVERSE DRIVE BELT REMOVAL
AND INSTALLATION
NOTE: The forward drive belt must be
installed before installing the reverse
drive belt.
The reverse drive belt (J, Figure 5-11) is
driven by the engine drive pulley (P,
Figure 5-11). When the Reverse Clutch
Control is engaged, it puts tension on the
reverse drive pulley which tightens the
belt between the engine drive pulley and
the transmission drive pulley (large pulley
located below the engine drive pulley).
The transmission drive pulley then turns
the main drive shaft inside the
transmission.
A. Removing the Reverse Drive Belt
1. Stop the engine, allow it to cool and
disconnect the spark plug wire before
working near the belts. Also remove the
ignition key on electric start models.
2. Remove the plastic belt cover (E,
Figure 5-8) by removing the two flange
locknuts.
3. Remove the front transmission cover
(A, Figure 5-20) by removing the four
self-tapping screws.
4. Using needle-nose pliers, reach inside
the left side frame and carefully unhook
the reverse idler spring (B, Figure 5-20)
from the hole in the frame.
5. Remove the wire belt guide (C, Figure
5-21) by removing the locknut and flat
washer from the pulley mounting screw.
Do not remove the screw or the pulley.
Loosely reinstall the locknut and flat
washer on the screw for safe-keeping.
