Adjustments

SPEED SELECTOR PIVOT ADJUSTMENT

The speed selector is factory set for optimal performance at each forward and reverse speed setting. However, if drive system components have been replaced, adjust- ment 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. Pull the two rods apart and tighten the shift rod hardware (B).

TRACTION DRIVE CLUTCH CABLE ADJUSTMENT

Initial Adjustment

The traction drive clutch cable should initially be adjusted so that there is no slack in the cable when moved slightly from side to side, but bellcrank arm remains in fully down position. To adjust tension on the cable:

1.Loosen adjustment hex nut (Figure 20) by holding the adjusting flats and turning adjustment hex nut.

2.Tighten adjustment screw by turning adjustment flats and holding screw. The adjustment screw is a phillips screw and the head can be held or turned by inserting a screwdriver through the traction drive clutch cable spring. Tighten just until slack in cable is removed.

3.Tighten hex nut securely. The unit should able to be pushed forward and back freely.

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 cables 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 cable has been over-tightened. To remedy, loosen tension on clutch cable slightly, and recheck.

Run-In Adjustment

1.After 5 hours of use, check for proper adjustment. Readjust clutch cable if necessary by increasing ten- sion on cable. A small amount of bellcrank arm movement is permissible if unit passes operating checks described in the Caution at left. Optimal adjustment provides 3/16" clearance between traction drive disc and rubber ring on friction disc when drive lever is released (see Figure 15 for fric- tion disk location).
