INSPECTION
MAINSHAFT/SPROCKET/HUB INSPECTION
Inspect the splines on the hub and shaft and the teeth on the sprocket. Minornicks and scratches can be smoothed
with an oilstone. However, replace any part that is damaged.
Check the contact surfaces in the sprocket bore and on the mainshaft. Minornicks and scratches can be smoothed
with 320-400 grit emery cloth but do not try to salvage the shaft if nicks or wear is severe.
