WARNING
Figure 19. Traction Drive Clutch Rod Adjustment
Do not over-tighten, as this may cause traction
drive to engage without depressing the traction
Drive Control (bellcrank arm must remain in down
position).
Run-In Adjustment
1. After 5 hours of use, check for proper adjustment.
Readjust clutch rod if necessary by increasing ten-
sion on rod. A small amount of bellcrank arm move-
ment is permissible if unit passes operating checks
described in the Caution at left. Optimal adjustment
provides 1/32" clearance between traction drive
disc and rubber ring on friction disc when drive
lever is released (see Figure 15 for friction disk loca-
tion).
Verify that the rods are not over-tightened: With
Speed Selector in position 1 and traction Drive
Control fully released, push snowthrower
forward. The unit should move forward freely.
If unit does not move forward freely, the rod has
been over-tightened. To remedy, loosen tension
on clutch rod slightly, and recheck.
