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. 3. Install the transmission bearings with the flange facing the gear (Fig. 054). Fig 054 MVC-470 Fig 052 MVC-466 2. Install the trust washer on the side of the gear with the shorter hub, away from the gear teeth (Fig. 053). 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. Fig 053 MVC-468 3-8 WPM Drive Systems Manual
