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).
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).

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).
