c.
After welding the cap and nut to the tubing, slot the tubing as shown. This will allow the special adapter to slide
over the keyway and will then act as a large socket. A torque wrench can then be used to apply the proper torque. Turn
the torque wrench so that the drum turns in the spoolout direction or lowering direction.
6-7. 4 Test for Proper Brake Assembly:
a.
After the brake has been adjusted to the proper torque setting, disengage the clutch, operate the winch in the
spool-in direction (hoisting direction).
b.
Allow the winch to run in this direction for one minute. Place your hand on the safety brake housing and, if it is
not heating, change the power take-off lever to the reverse position. Run the winch for another minute and hold your
hand on the safety brake. It should begin to heat.
c.
When these conditions exist, proper installation has been made. If heating becomes noticeable when running
the winch in forward rotation (reeling in), the brake should be again disassembled. When disassembled, place the brake
balls in the correct slots in the cam plate, then carefully follow the instructions for reassembling and checking the brake.
6-8 WINCH OVERHAUL (Figure 6-4)
6-8.1 Disassembly.
a.
Drain oil from gear housing by removing pipe plug (56) from gear housing.
b.
Shift clutch into the engaged "IN" position. Remove frame angles (2) from Winch Assembly.
c.
Remove two capscrews (40) from clutch housing (14) and unlatch shifter assembly.
d.
Remove clutch housing from end of drum shaft. Press in on retainer plate (60), to relieve the spring tension and
remove the retainer ring (62).
e. Remove four capscrews (31), retainer plate (60) and springs (66).
f. Remove clutch spacer (23) and slide the locking ring (7) from the clutch. NOTE: The locking ring cannot be
removed unless the clutch is engaged, with dowel pins (58) seated in the shaft keyways.
g.
Rotate the drum so the eight balls (27) and four dowel pins (58) can be removed.
h.
If necessary, the clutch (6) may be disassembled from the drum by removing eight capscrews (37).
i.
