SINGLE SPEED BEVEL GEAR TRANSMISSION Transmission Disassembly 1. Remove the 4 screws holding the cover on the transmission. The axle, bearings, and bevel gear can be lifted out (Fig. 106). Transmission Assembly & Installation Assemble in reverse order. See Axle Assembly and Installation Tips following. Axle Assembly Tips 1. The same axle is used for both front and rear wheel drive models. There are two holes in the axle about one inch apart. Rear wheel drive models use the hole about 4-3/4" (12cm) from the end. Slip the gear on such that the teeth and the longest hub face the short 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 (Fig. 108). Fig 106 MVC-462 2. Since the pulley was previously removed, the input shaft will now slip out of the transmission case. 3. If the input bearing is to be removed, press it out now. 4. Slide the bearings and thrust washer off the axle. Drive the roll pin out and the bevel gear can then be removed (Fig. 107). Fig 108 MVC-469 3-24 Fig 107 MVC-470 WPM Drive Systems Manual
