4. Loosen the forward idler sheave bolt (E) and
slide the idler sheave down to tighten the belt
(G) (this also increases distance between clutch
handle and stationary handle); slide the sheave
up to loosen the belt (this also reduces distance
between clutch handle and stationary handle).
5. Tighten the idler sheave bolt.
6. Recheck handle and bolt positions. Repeat as
necessary to adjust belt tension.
NOTE: After adjusting the forward belt, it may contact
the belt guide when engaged causing a whining noise.
To stop the noise, bend the guide up out of the belt’s
way.
7. Pull the clutch handle to tighten the reverse
propelling belt. Observe the position of the
clutch plate bolt (C). It should not touch the end
of the slot (D). If the bolt is in the proper
position, proceed to step 11; if not, continue with
step 8 to readjust reverse belt tension.
NOTE: If the reverse belt is too tight, it will require
excessive clutch handle pressure to propel machine
in the forward direction. It may also cause the
machine to creep backward when the handle is
released. If the reverse belt is too loose, the machine
will not propel backward.
8. Loosen the reverse idler sheave bolt (H) and
slide the idler sheave to the rear to tighten the
belt (F); slide the sheave forward to loosen the
belt.
9. Tighten the reverse idler sheave bolt (H).
10. Pull the clutch handle to recheck the position of
the clutch plate bolt (C). Repeat as necessary to
adjust belt tension.
11. Check steering effort. After repairing or
replacing drive system parts, effort may
increase due to poor alignment. To correct, do
the following:
A. Loosen the bearing flanges as well as the
split coupling bolts.
B. Snug one split coupling bolt.
C. Align the propelling belts. Check for
clearance between the differential and the
locking collar.
NOTE: Minimum clearance between differential and
sheave is 0.3 mm (0.010 in).
D. While holding belt alignment, pull the shaft
away from the differential.
E. Tighten the center and left bearing flanges.
Check for hard rotation of shaft.
F. Tighten the center and left bearing collars.
G. Pull the short differential shaft away from
differential to spread the differential gears.
H. Tighten the right side bearing flange. Tap
bearing before tightening.
I. Tighten the right bearing collar.
J. Check for free spinning of differential.
Loosen the center and right bearing flanges
if it is not spinning freely. Tap and retighten.
K. Align and tighten sprockets. Chains must
be slack to minimize steering effort.
12. Reinstall the access cover, and right side cover,
and bumper.
