5-8.1 Traction Drive Clutch Adjustment. Adjust
traction drive clutch as follows: 1993 and Prior:
1. To check the adjustment of traction drive
clutch, move shift lever to the fast reverse posi-
tion then all the way forward to sixth (6) posi-
tion. It should move freely.
NOTE
Before 1992 there was a neutral position and
only 5 forward speeds and 1 reverse speed. In
1992 neutral was removed. Forward speeds
were increased from 5 to 6. Reverse was
increased to 2 speeds. To obtain neutral on the
later models, release the clutch lock or the
handle.
2. If it does not move to all positions, adjust as
follows:
a. Loosen lock nut and loosen the cable sev-
eral turns.
b. Check movement of shift lever again.
c. Tighten lock nut against cable when cor-
rect adjustment is reached.
1994 to Present:
1. With the snow thrower tipped forward (be cer-
tain to drain the gasoline or place plastic film
under the gas cap if the snow thrower has
already been operated), remove the frame
cover underneath the snow thrower by remov-
ing six self-tapping screws.
2. With the traction drive clutch released, there
must be clearance between the friction wheel
and the drive plate in all positions of the shift
lever. With the traction drive clutch engaged,
the friction wheel must contact the drive plate.
See Figure 5-69.
3. If adjustment is necessary, loosen the lock nut
on the traction drive cable and thread the cable
in or out as necessary. Tighten the lock nut to
secure the cable when correct adjustment is
reached. Reassemble the frame cover.
NOTE
If you placed plastic under the gas cap, be cer-
tain to remove it.

push forward on the left hand clutch grip
(depress rubber bumper). There should be
