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 18) 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 19).

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.
