Hex shaft

F.The small sprocket is retained to the hex shaft with a key and set screw.

G.The large sprocket just rotates on the bearings, so it will slide off the shaft.

12.The drive shaft assembly is held in place by a front pillow block bearing and a bearing on the rear with spacers to locate everything front to rear. Remove two cap screws holding each bearing in place. Remove the shaft assembly (Figure 79).

ASSEMBLY — TORO MODELS 38065, 38080, 38085

Preparation

14.Before assembling something with a new bushing, wipe the bushing with a clean shop towel. This should remove any debris that might have gotten into the bushing during shipping and storage.

15.These are oil-impregnated bearings. However, before installing them on a shaft, wipe the bearing surface with a clean shop towel. Then apply a light coat of engine oil to the bearing surface.

16.Apply oil sparingly in this drive system. Excess oil will be thrown around during operation and can cause the friction wheel to slip.

17.Wipe the drive plate and friction wheel with alcohol to make sure they are clean, to prevent slippage.
