TRACTION DRIVE SYSTEM
ADJUSTMENT
Speed Selector Pivot Adjustment
The Speed Selector is factory set for optimal perfor-
mance at each forward and reverse speed setting.
However, if drive system components have been
replaced, adjustment may be necessary.
Adjust as follows:
1. Move the ground speed control (A, Figure 19) fully
forward.
2. Loosen the hardware (B) securing the upper and
lower shift rods.
3. Push the lower rod (C) down fully (into the housing).
4. Make sure the ground speed control (A) is in the full
forward (5th gear) position. Tighten the shift rod
hardware (B).
Traction Drive Clutch Rod & Spring
Adjustment
INITIAL ADJUSTMENT
The traction drive clutch rod should initially be adjusted
so that there is no slack in the rod when moved slightly
from side to side, but bellcrank arm remains in fully down
position. To adjust tension on the rod:
1. Loosen adjustment hex nuts (Figure 20).
2. Tighten bottom hex nut while holding rod. Tighten
just until slack in rod is removed.
3. Tighten upper hex nut securely.

WARNING
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).
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.
