To prevent serious damage to winch, do not run engine while oil is drained from winch.
The pressure filter is located behind the right hand, eight-bolt access cover. Remove the cover, locate the spin-on pressure filter and remove the filter element with a strap wrench.Lubricate the filter gasket and adapter threads with hydraulic oil and install new filter element onto filter head. Tighten 1/2 - 3/4 turn after seal ring makes contact with filter head.Start tractor and operate engine at low idle. Correct any leaks.The indicator light may come on for a short time during initial cold start-up but should go out as the oil warms up. If the light stays on, this indicates a restricted filter element, sending unit stuck in the bypass position or accidentally grounded sending unit wire.3. Control Cable and Pressure Adjustment While the access cover is removed, it is advisable to check control cable adjustment and hydraulic main relief pressure. Place the Power Shift control lever in the center "Brake-On" (neutral) position. Install the yoke pins into the cable yokes/control valve spools and secure with hitch pins. The yoke pins should slip easily into the bores without any binding. The control valve spools are spring centered. If you notice any binding, turn the cable adjusters in or out until you obtain a "free pin" condition.Make certain accumulator stored oil supply has been discharged as described earlier. Install an accurate 0-600 psi (4140 kPa) gauge onto the gauge port next to the control cables. Start the tractor and operate the engine at approximate 800-1000 RPM until pressure stabilizes. The maximum pressuring during "charging" mode should peak at 400 psi (2760 kPa). Pressure will slowly fall back approximately 15-20% from the relief setting then quickly return to 400 psi (2760 kPa) when the valve cycles.If adjustment is required, locate the adjustment screw hole behind port "P" of the control valve. With a 1/4in. Allen key, loosen the outer lock screw. Insert a 3/16 in. Allen key through the lock screw and turn the adjusting screw clockwise to increase peak pressure; counterclockwise to decrease peak pressure. Tighten the lockscrew. TIP: It may be helpful to place the controls in Brake-Off to use some oil in the control circuit and cause the valve to slowly "cycle" so that peak pressure may be more easily observed.Stop engine, discharge accumulator stored oil supply as described earlier and move hydraulic gauge to the "B" test port on the brake housing. A 1/4 NPT adapter will be required.Start tractor and operate engine at approximately 800-1000 RPM. Place Power Shift lever in the Brake-Off position and observe BRAKE-RELEASE oil pressure. Loosen cable adjuster or cable yoke jam-nut and adjust brake control cable to achieve approximately 300 psi (2070 kPa) BRAKE-RELEASE pressure.Stand away from service access of winch and return Power Shift lever to the BRAKE-ON (neutral) position. BRAKE RELEASE pressure must return to 0 with the controls in BRAKE-ON (neutral) position. TIP: Optimum BRAKE-RELEASE pressure is the highest pressure you can achieve while
