We dismantle the winch for replacement or repair
We replace the winch in case of the following malfunctions:
- - oil leakage through the cuffs as a result of their damage;
- - breakage of the cracker and destruction of the turns of the lead screw of the cable laying machine;
- - deflection of the cable guide shafts and jamming of the guide rollers;
- - wear of the hole at the end of the biscuit in the body of the cable layer;
- - wear or breakage of the teeth of the globoid pair of the winch gearbox;
- - cracks or holes in the winch crankcase
To complete the task, you need tools: wrenches 12x13, 14x17, 17x19, 22x24, ring wrench 19x22, screwdriver, hammer, crowbar, mounting blade, lifting and transport device for removing gearboxes, pulling device
We remove the winch cable for this:
We unscrew the nuts of the clamps and remove the two boards of the platform flooring, located above the winch
We loosen the cable fastening manually by turning the winch gear lever
We unpin and take out the pin 4 (Fig. 1) and the hook 5, knock out the wedge 3, remove the thimble 2. Extend the cable back
We start the engine, fill the pneumatic actuator of the brake systems with air. Turn on the parking brake
Set the transfer case control switch to the neutral position
Set the power take-off control switch to the “on” position
Turn on the reverse gear in the gearbox
Unwinding the cable
Notes: Manually adjust the cable slack. If necessary, you can unwind the cable manually, to do this, turn off the winch drum shaft by turning the lever
Disconnect the cable from the winch drum by unscrewing the nuts 11 (Fig. 2) securing the bracket, and remove the bracket 9
After the cable has been removed, drain the oil from the winch gearbox housing by unscrewing two plugs 34 (Fig. 3)
Disconnect the winch drive rear cardan shaft from the winch
Remove the protective sleeve from the cover of the rod cover of the fork of the winch gearbox
We moor the winch, unscrew the bolts securing the winch to the rear cross member and the bolts securing the front cross member to the frame
Guiding and supporting the winch with a crowbar that needs to rest against the rear crossbar, move the winch forward and turn it so that it passes between the frame spars.
We lower the winch and pull it out from under the car (this operation is performed by two people)
Note: when using a dolly, lower the dolly table or raise the rear of the vehicle and roll out the dolly
Installing the winch
Pour oil into the winch gearbox housing to the level of the control plug
We wrap the winch with slings and wind it under the car
We moor the winch, raise it between the spars and turn it so as to install the front cross member on the frame brackets
We screw in the winch bolts to the rear cross member and the front cross member to the frame brackets
We put a protective sleeve on the cover of the fork rod cover of the winch gearbox
Attach the rear driveshaft to the winch
Installing the cable
Before installing the cable, we melt or wrap the ends with wire
Before fixing the cable, make sure that the housing of the guide roller holder is in the extreme left position, while the cable fastening bracket on the drum must be in the upper position
Passing the cable forward
We fix the cable in the thimble with wedge 3 (Fig. 1), install the hook, pin and cotter it
We start the engine, fill the pneumatic actuator of the brake systems with air. Turn on the parking brake
Set the transfer case control switch to the neutral position
Set the power take-off control switch to the “on” position
We turn on the first gear in the gearbox. We wind the cable, after three or four turns we tightly knock them down to the left flange.
After the fifth layer of winding, it is allowed to run a coil on a coil.
To bring it to the transport position, we hook the cable hook on the left towing hook, turn on the winch and first gear in the gearbox and smoothly pull the cable (this operation must be performed by two people)
Technical condition. The brake should not heat up for 1-3 minutes above the temperature maintained by the hand. When heated, unscrew the nut 45 (Fig. 3) by two or three turns
installing two platform floor boards
