WARNING
Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to
a complete stop, disconnect spark plug wire and move wire away from spark plug.
Failure to follow these instructions can result in serious personal injury or property damage.
front of the unit (not the operator's posi-
tion). If the belt tension is correct, rein-
stall the belt cover and secure it with the
two nuts.
• If the guide mark is aligned with the
guide pin, or moves to the right side of
the guide pin, then the belt is too loose
and the tension must be readjusted as
described next.
3. The reverse idler pulley (L, Figure 5-13)
regulates the tension that is applied to the
reverse drive belt (P). The following
adjustment will allow the reverse idler
pulley to apply more tension to a loose
belt.
4. Remove the belt cover.
5. Slip the reverse belt (P, Figure 5-13) off
the engine-driven reverse (upper) pulley.
6. On the right side of the unit (as viewed
from operator's position), remove the
hairpin cotter from the clevis pin (R,
Figure 5-13) that connects the reverse
idler arm (K) to the reverse adjustable link.
Push inward on the reverse idler arm (K)
and remove the clevis pin (R).
7. There are two holes in the reverse
adjustable link (S, Figure 5-15). Push
inward on the reverse idler arm (K) and
install the clevis pin (R) through the inner
hole in the reverse adjustable link (S) and
out through the single hole in the reverse
idler arm (K). Secure the clevis pin with
the hairpin cotter.

hole of reverse adjustable link.
8. Reinstall the reverse belt (P, Figure 5-13)
on the reverse (upper) pulley, making sure
the belt is located to the inside of the
reverse idler pulley (L, Figure 5-13).
9. Reinstall the belt cover and secure it
with the two nuts.
IMPORTANT: If, in future tests for reverse
belt tension, the guide mark should again
align with or move to the right side of the
guide pin, it means that the reverse belt is
worn beyond adjustment. Before installing
a new belt, you must return the clevis pin
to the OUTSIDE hole in the reverse
adjustable link.
FORWARD DRIVE BELT REMOVAL
AND INSTALLATION
D
REAR
Figure 5-16: Belt drive system.
This model has two forward speeds (High
R
and Low) and one reverse speed. The
K
forward engine pulley (D, Figure 5-16) has
two grooves for the two forward speeds.
The reverse engine pulley (A, Figure 5-16)
has one groove for the one reverse speed.
The transmission pulley (C, Figure 5-16)
has three grooves. The groove closest to
the engine is for the reverse belt. The
middle groove is for the High speed
forward belt range; the rearmost groove is
for the Low speed forward belt range.
Section 5: Maintenance
A. Removing the Forward Drive Belt:
1. Stop the engine, allow it to cool and
disconnect the spark plug wire before
working near the belts.
2. Remove the reverse drive belt
(A, Figure 5-16) by following the Remov-
ing the Reverse Drive Belt instructions in
this section.
3. Move the forward drive belt (B, Figure
5-16) completely off the engine forward
drive pulley (D).
4. Slip the forward drive belt completely
off the transmission drive pulley (C, Figure
5-16) by moving it to the front of the
pulley.
5. Pull the forward drive belt up and off
the pulleys by feeding the bottom half of
the belt in between the engine and trans-
mission pulleys.

B. Installing the Forward Drive Belt:
1. The reverse drive belt must be removed
before installing the forward drive belt.
2. Slip the forward drive belt down
FRONT
between the rear of the engine forward
drive pulley (D, Figure 5-16) and feed the
bottom half in between the engine and
transmission pulleys (see Figure 5-17). Be
sure that the belt is to the inside of the
forward idler pulley and forward belt guide
(see J and I, Figure 5-12).
