Lubrication
Remove any accumulated dirt from the freewheel with a brush and
a degreaser. Disassembly of the freewheel is a complicated procedure
requiring special tools, and should be left to a specialist. Apply oil to
the freewheel whenever you lubricate the chain, taking care to wipe off
any excess.

Inspection
Like the chain, the freewheel must be kept clean and well lubricated. If
the chain has become worn and needs replacing, then it is likely that
the freewheel will also have become worn and should also be replaced.
Take the chain off the freewheel and rotate it with your hand. If you
hear a grinding noise or the freewheel stops suddenly after spinning it, it
may need adjustment or replacement. Such action is beyond the scope
of this manual and you should consult a specialist.
