7. There are two holes in the reverse
adjustable link (S, Figure 4-16).
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.
8. Reinstall the reverse belt (P, Figure
4-14) on the reverse (upper) pulley,
making sure the belt is located to the
inside of the reverse idler pulley (L,
Figure 4-14).
9. Reinstall the belt cover and se-
cure 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 cle-
vis pin to the OUTSIDE hole in the
reverse adjustable link.

ForwardDriveBelt Removal
AndInstallation
NOTE: This model has one forward
speed (High) and one reverse
speed. The High Speed groove in
the forward engine pulley (the
groove closest to the engine) is the
only groove that should be used in
this pulley. Do not use the groove in
the forward engine pulley that is fur-
thest from the engine. The reverse
pulley hasjustone groove. The trans-
mission pulley has three grooves--
do not use the groove closest to the
transmission housing.
Removingthe ForwardDrive 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
completely (A, Figure 4-17) by follow-
ing the "Removing the Reverse Drive
Belt" instructions in this section.
3. Move the forward drive belt (B,
Figure 4-17) completely off the en-
gine forward drive pulley (D).
4. Slip the forward drive belt com-
pletely off the transmission drive pul-
ley (C, Figure 4-17) by moving it to
the front of the pulley.
5. Pull the forward drive belt up and
away by feeding the bottom half of
the belt in between the engine and
transmission pulleys.
Installingthe ForwardDriveBelt:
1. The reverse drive belt must be re-
moved before installing the forward
drive belt.
2. Slip the forward drive belt down
between the rear of the engine for-
ward drive pulley (D, Figure 4-17)
and feed the bottom half in between
the engine and transmission pulleys
(see Figure 4-18). Be sure that the
belt is to the inside of the forward
idler pulley and forward belt guide
(see J and I, Figure 4-13).
3. Slip the forward drive belt down
and over the front of the transmis-
sion pulley (C, Figure 4-17).
NOTE: For additional working room,
loosen the reverse belt guide (V, Fig-
ure 4-13) and twist it out of the way.
4. Put the lower half of the belt into
the middle groove of the transmis-
sion pulley (C, Figure 4-17).
5. Put the upper half of the belt on
the engine forward drive pulley in
the groove closest to the engine (B,
Figure 4-17).
IMPORTANT: Make sure that the ,.
forward drive belt is to the inside of
the wire belt guide (I, Figure 4-13)
and the forward idler pulley (J, Fig-
ure 4-13).
6. If you loosened the belt guide,
wait until the reverse drive belt is in-
stalled before securing the belt
guide.
7. Install the reverse drive belt.
8. Install the belt cover and secure it
with the two nuts.
9. If you installed a new belt, check
the tension after two hours of opera-
tion.
