If a complete tear down is not
necessary, make sure the
input shaft (21) does not
move during removal of the
drum. If the shaft is allowed
to move,
the input spacer
(104) will fall into the gear set
ultimately causing failure to
the gear section of the winch.
The gear cover (3) will have to
be removed to re-position the
spacer on the input shaft.
