7. This should normally complete the disassembly of the
secondary drive. However, if complete disassembly is re-
quired including the drum bearings and seals, refer to
Figure 5J-15 and remove the housing spacer and inner ring
gear. Then, block the winch drum so that it cannot drop,
remove the mounting plate (Figure 5J-16) capscrews and
lockwashers, and remove the mounting plate. The drum can
now be removed from its base for replacement of bearings
and seals as required. Note that the drum sleeve is pressed
into the drum and cannot be removed until the mounting
plate is removed.
REASSEMBLY OF FINAL DRIVE. In general, reassembly
is the reverse of disassembly. Only where an adjustment or
a procedure is not the exact reverse of disassembly will
additional detail be given in the following reassembly
procedure. Reassemble from the final drive end as follows:

the ring gear and housing ring firmly against the mounting
plate.
