necessary.

attachment belt.

c. To decrease the distance between the clutch

lever and handlebar, move the idler away

e. Check clutch lever measurement.

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 24).

6. Repeat steps 3–6 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 21.

8. Replace belt cover.

9. Check that auger/impeller stops within 3 seconds

after attachment clutch/impeller brake lever is

released.

TRACTION DRIVE CLUTCH ADJUSTMENT

If drive slips, adjust traction clutch to compensate for

friction disc wear.

To test traction clutch (Figure 23):

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.

To adjust traction clutch (Figure 26):

1. Loosen jam nut on traction clutch cable

adjustment barrel.

2. Turn adjustment barrel down the cable to

decrease the distance between clutch lever and

handlebar.

3. Turn the adjustment barrel up the cable to

increase the distance between clutch lever and

handlebar.

4. Check traction clutch lever distance and repeat

adjustment steps if necessary.

5. Tighten jam nut on traction cable adjustment

barrel.
