Checking and Adjusting Reverse Clutch Belt Tension

Checking Reverse Clutch Belt Tension

The reverse clutch belt (D, Figure 5-9) needs adjustment if the belt slips in reverse or if there is no reverse. See Adjusting Reverse Clutch Belt below.

Adjusting Reverse Clutch Belt

1.Before adjusting the belt, shut off

engine, allow the engine and muffler to cool down, disconnect the spark plug wire, and remove the ignition key on elec- tric start models.

2.Remove the two nuts (C, Figure 5-13) and remove the belt cover.

3.Reverse belt tension adjustments are done with the reverse clutch cable adjuster located on the left side of the machine near the engine (D, Figure 5-14). Use two 1/2" open-end wrenches to loosen the two adjuster jam nuts (E) a few turns.

5.Tighten both jam nuts securely.

6.Reinstall the belt cover.

7.Move the unit to an open area and test the reverse operation. Repeat this proce- dure if the unit does not respond when the reverse clutch is engaged.

FORWARD CLUTCH BELT REMOVAL AND INSTALLATION

The forward clutch belt (K, Figure 5-15) engages the engine pulley (I) and the transmission pulley (J) when either Forward Clutch Control Lever is pulled up against the handlebar. The lever draws the forward clutch cable (G) tight which causes the forward clutch idler pulley (H) to apply pressure to the forward clutch belt. This causes the pulleys to turn for Forward movement.

Removing Forward 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.Remove the belt cover by removing the two nuts (C, Figure 5-13).

3.Move the reverse clutch belt (B, Figure 5-16) out of the way. (You do not need to completely remove the belt.) Press the reverse idler pulley inward to create slack, and then slip the bottom half of the belt completely off the transmission pulley (A, Figure 5-16). Pull the bottom half of the belt out of the housing and let it hang off the outside of the unit (B).
