Clutch Maintenance
Using an inspection mirror, inspect the clutch
every 1000 hours of operation or yearly,
whichever occurs first. If clutch removal is
necessary, clean the shoes and drum, regrease
bearings or replace if they are worn. Inspect
anchor bushings, shoe lining and springs for wear
and replace if necessary.
