Usage:
Before starting any repair procedures, be sure to thoroughly clean the parts to be removed and adjacent areas on the tractor to avoid entry of dirt into the winch. Do not leave any ports or access openings exposed to the weather. Seal or cap the openings to prevent entry of dust, moisture, or other foreign material. Cap or plug all exposed hydraulic ports and fittings.
During disassembly, care should be taken not to damage gaskets, shims, seals and o-rings that are to be reused. Replace any such parts that are damaged or otherwise defective. Certain o-rings and seals specified in the replacement instructions must not be reused. In general, seals and o-rings that work under operating hydraulic pressures, or that require extensive disassembly to replace, should be replaced with new parts at time of reassembly.
During assembly, use a suitable thread sealing compound on all capscrews that penetrate the winch case. Take care to prevent excess sealing compound from entering the winch case.
Maintain strict cleanliness during rebuild to prevent entry of dirt or moisture into winch case. Hydraulic components should be rebuilt under the cleanest possible conditions.
Winch Removal
Place tractor and winch in level position and drain oil from winch into a suitable container. Install drain plug securely after oil has been drained.
Control Cable Removal
Remove the eight-1/2 in. capscrews which secure the right hand cover plate to the winch. Remove the cover plate and locate the control valve and cables.
Carefully remove the hitch pins and clevis pins which connect the control cables to the control valve spools.
Remove the fasteners which secure the control stand to the tractor console. Lift the control stand up clear of the console to gain access to the control cables.
Freespool Control:
Remove the four Phillips head machine screws from the long cover which faces the operator. Remove the U-bolt securing the cable housing to the controller housing. Remove the cotter pin and clevis pin, which fastens the cable core to the lever bellcrank, and then lift the cable free of the controller housing.
Power Shift Control Lever:
Remove the six through-bolts from the control stand and separate the two cable support housing halves. Move the control lever slightly to expose the wrench flats on the plungers.
While holding the plunger with one wrench, remove the sliding lock screw from the plunger and remove the cables from the controller.
Secure the control cables to the winch to avoid damage during winch removal.
Support the winch with a suitable hoist and remove nuts and capscrews securing the winch to the tractor adapters.
Move winch away from tractor cautiously to avoid damaging the PTO pilot and shaft. Cover PTO opening in rear of tractor to prevent entry of dirt or moisture.
Winch Installation
Remove dirt, paint and rust from mounting surfaces of winch and tractor adapters.
Coat splines of PTO shaft and couplings (if equipped) with general purpose grease. Lubricate and install o-ring(s) on to winch PTO pilot (if equipped).
Remove winch top cover to gain access to bevel gears.
Carefully install winch on tractor while guiding winch PTO pilot into tractor and rotating bevel gears to align PTO shaft splines.
Install winch top access cover plate.
Fill winch to proper level with recommended oil.
Route control cables to the control stand in such a manner to avoid chaffing and binding.
Control Cable Installation and Adjustment
Freespool Cable
Winches equipped with freespool are shipped from the factory with the internal linkage in the "Engaged" position. This setting should hold the threaded cable end in the outermost position.
Check the condition of the o-ring seal around the cable end housing and replace as required. If required, install the hex nuts and the clevis onto the cable core, and adjust to achieve 7/32 in (5.6 mm) of cable core projecting beyond the nut. Slip the clevis over the lever bellcrank and install the clevis pin and cotter pin.
Position the o-ring on the cable housing so it will fit into the groove in the controller housing. Install the U-bolt over the cable and tighten the hex nuts to 90 lb-ft (10 N·m) torque. Install the cover onto the controller housing.
Power Shift Control Cables
Remove the six through-bolts from the control stand and separate the two cable support housing halves. Hold the control stand in your left hand with the mounting bolts at 6, 9 and 12 o'clock positions. Moving the lever up and down from the 12 to 6 o'clock positions should actuate only the bottom plunger; nearest the 5 o'clock position. Mark this plunger as the "Clutch" control plunger.
Moving the lever from the center toward the 9 o'clock position should move only the top plunger; nearest the 11 o'clock position. Mark this plunger as the "Brake" control plunger.
Install the sliding lock screw over the cable core with the threaded end out. Apply two drops of Loctite 242 or equivalent to the cable core threads and install the threaded bushing onto the cable core until it is level with the end of the cable core.
Install the "Brake" cable, which is installed in the outer-most position on the RH side of the winch, to the "Brake" plunger. Install the "Clutch" cable, which is installed in the innermost position on the RH side of the winch, to the "Clutch" plunger.
Move the lever slightly to expose the wrench flats on the plunger.
While holding the plunger with one wrench, tighten the sliding lock screw to 50 lb-ft (68 N·m).
Install the cable support housings onto the controller and guide the groove of the cable housings into the saddle of the cable clamps. Install the six through bolts and evenly tighten to achieve 25 lb-ft (34 N·m) torque.
If the power shift cable adjusters have been moved, check the cable adjustment by first installing the control cables to the control stand, as described above. Place the power shift control lever in the center, "BRAKE-ON" position. Install the clevis pins into the cable yokes/control valve spools, and secure with hitch pins. The clevis pins should easily slip into the bores without any binding. The control valve spools are spring-centered to neutral. If there is any noticeable binding, turn the cable adjusters in or out until you obtain a "free pin" condition.
With the cover removed, check the hydraulic main relief pressure as outlined in the "Control Valve Service" section of this manual. Install the winch cover plate and tighten the fasteners to 75 lb-ft (102 N·m) torque.
