Traction Drive Clutch Adjustment

5. Check Brake

When the clutch lever is disengaged, the brake must contact the attachment belt.

When the clutch lever is engaged, the brake must be more than 1/16 in. (1.6 mm) away from the belt and must not contact the frame (Figure 27).

6.Repeat steps 3–5 until attachment clutch lever distance and brake contact are correct.

IMPORTANT: If attachment clutch/brake cannot be adjusted within tolerances, see your Dealer for repairs.

7.Check belt finger clearance.

With clutch lever engaged, belt fingers should be 1/16–1/8 in. (1.6 - 3.0 mm) from belt. Adjust belt fingers as necessary. See Figure 24.

8.Replace belt cover.

9.Check that auger/impeller stops within 3 seconds after attachment clutch/impeller brake lever is released.

If drive slips, adjust traction clutch to compensate for friction disc wear.

To test traction clutch (Figure 28):

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 5-3/4 in. - 6-1/4 in. (14.6 cm - 15.9 cm), adjust the traction clutch.
