2.4 Hoisting Cable Rigging and Adjustment
2.4.1
Rotate the winch drum, using a 5/8” socket or
wrench to adjust the position of cable-end swivel fitting.
The pin in the swivel should be 29 ±1 in. above the
center line of the winch drum.
2.4.2
Attach the winch cable swivel fitting to the U-
shaped bail of the clevis. Insert the swivel pin in the
direction so that the head of the pin is on the side of the
clevis bail with the power cord. Insert the cotter pin into
the hole in the pin and bend both ends to secure it.
(See Figure 8)
inserted from behind and nuts tightened at the front.
When installed correctly the power unit mounting
bracket should be at the right side of the handhole.
(See Figure 7)
NOTE
If the winch assembly components were removed from
the plate to allow the plate to be inserted through the
handhole, realignment of the winch, power unit mount-
ing bracket and cable guide is required. To do so,
insert the power unit into the mounting bracket and
move the winch and/or bracket as required until the
power unit drive coupling slides freely onto the winch
input shaft. Center the cable guide over the winch
drum. Tighten all nuts securely.
