Cleanliness around all hydraulic components is of utmost importance. Before starting any repair procedures, be sure to thoroughly clean the parts to be removed, as well as adjacent areas on the tractor, to avoid entry of dirt into the winch and winch control system. 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 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 the time of reassembly. WINCH REMOVAL
Before servicing, makes sure any trapped oil pressure in the tractor hydraulic system has been relieved. Personal injury may result from a sudden release of oil pressure. Relieve trapped pressure by cycling the blade and winch control levers several times after the tractor engine has been turned off. Relieve any trapped oil pressure in the hydraulic reservoir by opening the fill cap. Turn the tractor's master electrical circuit switch off.
Hot oil may cause injury. Make certain the hydraulic oil has cooled to a safe temperature before servicing.
Place the tractor and winch in a level position and drain the oil from the winch into a suitable container. Install the drain plug securely after oil has drained completely. Note: Due to the configuration of the cable drum, a small amount of oil will remain within the drum cavity.Remove the winch motor hoses from the motor and brake valve. Remove the motor shift hose from the motor "X" port. Remove the motor drain hose from the motor. Remove the drum clutch hose from the elbow on the RH side of the winch case.Support the winch with a suitable hoist or platform and remove the nuts and bolts securing the winch to the tractor adapters, and move the winch away from the tractor. WINCH INSTALLATION
Winch weighs approximately 4,025 lb. (1,826 kg) without oil, cable and tractor adapters. Make certain the lifting equipment has adequate capacity. Attempting to lift the winch with inadequate equipment may result in personal injury or damage to the winch or property.
Remove dirt, paint and rust from the mounting surfaces of the winch and tractor adapters.Align the winch mounting holes with the adapter mounting holes, and install and tighten all fasteners to the recommended torque.Attach the winch control hoses to the motor, as defined in the Parts and Installation Manual.Fill the winch to the proper level with the recommended oil. Allow 15 minutes for the oil to flow through the gear train and fill the drum cavity before checking the oil level.Start the tractor engine and operate the engine at low rpm. Alternately place the winch control in the Reel-In,
