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.
