4. Adjust attachment clutch lever measurement, if
necessary.
a. Loosen attachment idler nut (Figure 20).
b. To increase distance between clutch lever
and handlebar, move the idler towards the
attachment belt.
c. To decrease the distance between the clutch
lever and handlebar, move the idler away
from the attachment belt.
d. Tighten idler adjustment nut.
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.
