Reverse the process for assembly. See the following
tips for special information.
1. Lightly grease the axle gear. Spread about
½ teaspoon of #2 general-purpose grease around
the circumference of the gear (Figure 119).
Excess grease will just fling off when the machine
is driven.

2. Lightly oil the drive chain with chain oil. If engine
oil is used, coat the chain then wipe the excess
off. As with the grease, the sprockets turning will
fling any excess oil around the drive system.
3. The drive plate must be clean and free of oil. Wipe
with alcohol or a solvent that does not leave a
residue. Oil on the plate will cause drive slippage.
4. When installing the traction shaft and friction
wheel, the bearings must be aligned. Loosely
install the assembly into the chassis. Rotate the
friction wheel and firmly strike each bearing a
couple of times with a rubber mallet (Figure 120).
The jolt will center the bearings. Secure the
bearings to the chassis side plates.

5. The rod that is welded to the slider must slip into
the end of the shift arm assembly (Figure 121).
