4.1 LUBRICATION
4.1.1
Winch The winch gear housing, as received from
Holophane is lubricated and sealed. Additional lubrica-
tion is not required.
4.1.2
Aircraft Cable The winch cable and hoisting
cables come from the manufacturer with a very light
coating of lubricant. This lubricant is desirable and
should not be removed. The winch cable should be
checked for wear and corrosion and cleaned with a soft
absorbent cloth and lubricated with a good quality acid
free grease on a regular service interval. In normal
atmospheres the cable should be serviced every two
(2) years. If during inspection it is found that there are
more than 12 broken wires in one lay of cord, the winch
or, hoisting cables, replace with a new set of cables
available from Holophane.
4.2 REPLACING THE WINCH CABLE
4.2.1
With the mounting ring latched, disconnect the
winch cable from the clevis.
4.2.2
Unwind the old winch cable, note the attachment
to the winch before disconnecting the cable and then
discard the cable.
4.2.3
Attach the new cable obtained from Holophane, in
the same manner that the old cable was attached.
4.2.4
While rewinding the winch, wrap as tightly and
neatly as possible to avoid crushing of the cable when
the load is applied to the winch cable.
4.3 PORTABLE DRIVE MOTOR SHAFT REPLACE-
MENT
WARNING
Do not attempt to adjust the torque limiting clutch or
replace the shear pin. If repairs are necessary, replace
damaged equipment with new equipment from
Holophane. Failure to follow these warnings may result
in injury or death.
If the torque limiter or shear pin need adjustment or
repair, return the complete power unit shaft assembly, as
shown in Figure 28, to Holophane for authorized factory
repair or replacement. Figure 28 gives instructions for its
removal. Reversing all steps is necessary for installing
the replacement.
