10. Turn the unit over and visually check to see if all inter-
nal teeth on the brake discs are aligned. If they are
not aligned, connect a hand operated hydraulic pump
to the brake release port and apply 500 PSI (3,450
kPa). This will allow the brake plates to be rotated
and aligned as the sprag clutch assembly is installed.
Install the sprag clutch assembly. The top of the sprag
assembly should be just below the spring stop (Item
93) when installed completely. If a hand pump was
used, release the pressure and remove the pump.
11. Carefully set the cable drum onto the support end
bracket (Item 2). Pay careful attention that the bearing
is not damaged and engages properly.
12. Install 2 eyebolts into the winch drive assembly and
use them to lift the drive. While the drive is suspended,
install a new O-ring (Item 24) under the lower flange of
the drive. Carefully set the drive into the winch drum,
aligning the holes in the drum with those in the bottom
flange of the drive.
13. There are two large notches in the end of the drive
gearbox. These must be rotated to install the cap-
screws and lockwashers (Items 4 and 5) that secure
the gearbox to the winch drum. This is done by rotat-
ing the motor coupling while keeping the drum from
turning. Continue this procedure and install all cap-
screws and lockwashers (Items 4 and 5).
NOTE:
To
obtain relative movement between the two sections
of the gearbox, the input shaft must be rotated in the
same direction as the motor turns to haul-in cable. Ro-
tating the shaft in the opposite direction results in the
entire gearbox and drum turning as a single unit.
14. Install the motor end bracket (Item 25) onto the winch
drive. Be sure to orient the end bracket so the vent
plug will be as close as possible to the 12:00 o’clock
position when the winch is installed.
15. Install the 10 capscrews and lockwashers (Items 29
and 30) securing the end bracket to the winch drive.
If necessary, rotate the motor end bracket until it is
aligned with the support end bracket.
