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).

spacers. Drive the roll pin out of the end of the

reverse drive plate. All the parts will slide off the
drive shaft.
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.
