SINGLE SPEED BEVEL GEAR TRANSMISSION

Assembly Tips

1. The same axle is used for both front and rear drive
versions. There are two holes in the axle about one
inch apart. Front wheel drive transmissions use the
hole in the axle that is about 5 ¾" (14.6cm) from the
end or closest to the center of the axle (Fig. 052).
Slip the gear on such that the teeth and longest hub
face the longer end of the axle. Drive the pin into
place. A double check is that neither of the pin holes
should be visible when the gear is installed.
2. Install the trust washer on the side of the gear with
the shorter hub, away from the gear teeth (Fig. 053).

3. Install the transmission bearings with the fl ange
facing the gear (Fig. 054).
4. If the input bearing was removed, press the new one
in until it bottoms in the case.
5. Fill the transmission case approximately 2/3 full with
#2 lithium base grease.
6. Assemble the bearing, bearing retainer, height of
cut plate, spring arm and pivot arm. Use two clamps
or vise grips to compress the assembly so the snap
ring can be installed.
Note: Install the snap ring with the sharp edge
facing away from the spring arm.
