A. Removing the Reverse Drive Belt:

1.Stop the engine and allow it to cool be- fore working near the belts. Be sure the spark plug wire is disconnected and on electric start models the ignition key is re- moved.

2.Remove the belt cover by removing the two nuts. For easier access to the trans- mission (lower) pulley, remove the trans- mission cover located below the trans- mission pulley.

3.Slip the reverse belt off the engine re- verse pulley (A, Figure 5-18). If necessary, work the belt off the pulley with your left hand while pulling the engine recoil starter rope with your right hand.

4.Push the upper half of the reverse belt downward to create slack in the belt. Then reach underneath the transmission and slip the belt off the front of the transmis- sion pulley (B, Figure 5-18).

5.Pull the belt up and past the engine re- verse pulley (A, Figure 5-18).

B. Installing the Reverse Drive Belt:

1.Slip the reverse belt down between the engine reverse pulley (A, Figure 5-18) and the engine forward drive pulley (C).

2.Loop the bottom half of the belt over the front of the transmission pulley (B, Figure 5-18) and seat the belt in the front groove of the pulley.

3.Place the belt to the inside of the reverse idler pulley (D, Figure 5-18) and the re- verse belt guide (V, Figure 5-12). Then slip the upper end into the groove of the engine reverse pulley (A, Figure 5-18).

4.If the reverse belt guide (V, Figure 5-12) was loosened previously, center the belt guide on the belt and tighten the mounting screw securely.

5.Install the belt cover and secure it with the two nuts. If the lower transmission cover was removed, reinstall it with the four self-tapping screws.
