3.Pull the reverse clutch belt downward and slip it off the transmission pulley (L, Figure 5-22).

4.Use two 1/2" wrenches to loosen the belt guide (R, Figure 5-22) on the reverse idler arm pulley. Try not to remove screw

(M) or pulley.

5.Remove the reverse belt and pull it out through front of transmission housing.

INSTALLING REVERSE CLUTCH BELT

1.Stop engine, allow it to cool and dis- connect spark plug wire before working near belts. Also remove ignition key on electric start models.

2.Install the forward clutch belt (see Installing Forward Clutch Belt in this section) before installing reverse belt.

IMPORTANT: The reverse belt has a ‘V” shape. When installing the belt, make sure that the widest (flat) side of the belt rides against the reverse idler pulley (N, Figure 5-22) and transmission pulley (L). If needed, the belt can be twisted “inside out” so that the “V” shaped side is on the outside and the widest side is on the inside.

3.Insert the belt down into the front of the transmission housing. Work the top half of the belt under the belt guide (R, Figure 5-22) and onto the reverse idler arm pulley (N).

4.Insert the belt down into the front of the transmission housing. Slip the top half of the belt onto the reverse idler arm pulley (N).

5.Pull the belt downward and loop the

bottom half of belt around the front groove of transmission pulley (L, Figure 5-22).

6.Mount the belt guide between the two flat washers on the idler pulley assembly and tighten snugly. The guide needs adjusting before fully tightening.

7.(You will need an assistant to help with this step.) Pull the reverse idler pulley (N) up to its highest point and position the belt guide (R) horizontally level as shown in Figure 5-23. Securely tighten the screw and locknut (M, Figure 5-22).

8.Pull back on the Reverse Clutch Control knob and make sure that the reverse clutch belt fully contacts the groove in the engine pulley (I, Figure

5-20). Release the knob and make sure that the belt is not tensioned against the reverse engine pulley (I). The belt may slightly contact the pulley, but not enough to turn the pulley. Adjust the cable for less belt tension if the belt presses to firmly against the reverse engine pulley. See Checking and Adjusting Reverse Belt Tension.

9.Reinstall the belt cover and secure it with two flange locknuts.

10.Test the unit in an open location.
