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).
