move the finger to the proper position.
Tighten the bolts and recheck the belt
finger clearance.

TRACTION DRIVE CLUTCH
ADJUSTMENT
If drive slips, adjust traction clutch to
compensate for friction disc wear.
To test traction clutch (Figure 26):
1. Put unit in first forward speed.
2. Without engine running, push unit
forward while slowly moving the traction
drive clutch lever toward the handlebar.
3. Measure distance between lever and
handlebar when the wheels begin to
brake. If distance is not 7 – 7-1/2 in.
(17.8 – 19.0 cm), adjust the traction
clutch.

cable to increase the distance between
clutch lever and handlebar.
2. Check traction clutch lever distance and
repeat adjustment steps if necessary.
3. Tighten jam nut on traction cable
adjustment barrel.
