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.
C. DRUM SECTION DISASSEMBLY
1. To remove the drum, first disconnect the
cable from the U-bolt (43) and lay aside. If
removing the drum from the motor end with
the motor and brake disassembled, first
remove the cotter keys (108) and clevis pins
(99) connecting the yoke (17) to the bracket
(110) & air cylinder (15).
You may need to remove the
air lines, so it’s a good idea to
mark them for re-assembly.
2. Support the weight of the drum with a hoist.
Remove the four cap screws (70) and the
nuts and washers (71, 72) on the bottom of
the brake housing (16). Disconnect the
airline running from the air cylinder (15) to
the brake housing (16). Remove the brake
housing by sliding it off of the output shaft
(20). At this time you will need to remove
two cap screws (70), nuts and washers (71,
72) from the frames (73 or 74). Do not
remove air cylinder (76) yet. Disconnect the
air line from the backside of the brake
housing (16) that goes to the brake band air
cylinder. You can now remove the brake
band assembly (77). Note which frame the
mounting bolts are on for re-assembly.
Inspect and replace, if needed.
3. Remove the outer thrust collar (48) by
loosening three set screws (89).
4. Remove the yoke (17), sliding clutch (13),
and coupler (12). Remove the three keys
(47) and the inner thrust collar (46).
Remove the drum using a hoist. Inspect the
bushings (9) in both ends of the drum.
You should also inspect the bushing
and seal (40, 41) that are located
in the end of the brake housing.
5. If necessary, replace the drum clutch (14) at
this time by removing six capscrews (45). If
you replace the clutch, make sure to torque
the capscrews to the specified torque upon
re-assembly. (See torque specifications
chart on page 28 of this manual.)
