Install woodruff keys (34) and the drum (35) onto the shaft. Install clutch hub (33) and two retaining rings (32).
Install knob (28), stem (29), spring (30), and shifter fork (31). Install drag brake by assembling nut (21), drag
brake spring (22), washer (23), link (24), cotter pin (25), link pin (26), and drag brake shoe (27). Install bracket
(20); then install pivot pin (19) and cotter pin (18). Install bushing (17) in bearing leg; then install bearing leg
assembly (16), fastening with two nuts (12), lockwashers (13), and capscrews (14).
Position the base angles (10, 11) and bracket (10) on the winch and fasten using nuts (4, 6), lockwashers (5), and
capscrews (7, 9). Loosely, install cable clamp (3), nuts (1), and lockwashers (2).
Install drain plug (71). Pour in the lubricant in the top fill plug (69) port. Add lubricant, per lubrication chart, to
the level plug (70) port; then install plugs (69, 70). Install the hydraulic motor. Install the winch in its mounting
and connect and tighten the hydraulic lines. Start the wire rope onto the drum and into the cable clamp (3).
Tighten the nuts (2). Rewind the wire rope onto the winch drum.
4-19.2 Winch Motor (Figure 4-45).
Before disconnecting lines, clean the port area of the motor. Remove hydraulic hoses and remove motor from
Set the motor in a vise with the output shaft down. Clamp across the edge of the bearing housing mounting
flange, NOT on the housing. Use some protective material, such as hard rubber or a strip of wood, between the
vise jaws and the flange.
Remove four bolts (1, 2) from the valve housing end of the motor. Carefully, lift valve housing (3) straight up,
taking care not to disturb the springs (12) and balance ring (13). (During disassembly, observe how the motor
comes apart to facilitate reassembly.)
From the valve housing, remove plug assembly (4), o-ring (5), check plug assembly (6), o-ring (7), spring (8),
and steel ball (9). Also, remove the small o-ring (10) and the large seal (11).
Remove three balance ring springs (12) and the balance ring subassembly (13). Remove the inner and outer
face seals (15, 16) from the balance ring. Lift off valve (17) and valve plate (18). Remove one seal (19) from
the valve plate. Remove valve drive (20), geroler (21). Retain the rollers in the geroler ring if they come loose.
Remove one seal (22) from each side of the geroler.
Remove drive (23) and the other large seal (19) from the bearing housing (31). Then turn the bearing housing
with output shaft up and re-clamp it in the vise. Loosen six bolts (24); remove bolts, retainer (25), seal (26), and
shaft seal (27). Use a small screwdriver and remove dust seal (28), being careful not to damage the bore of the
retainer. Remove the shaft and bearing assembly (using a press if required); then, being careful not to damage
the housing bore, remove the shaft face seal (30) from the bearing housing (31).
