Information:
Coupler Cylinder Rod End Relief Valve
Make reference to on first page of Loader Hydraulic System Testing And Adjusting section.
Relief Valve - Typical Example
(1) Locknut. (2) Cover nut. (3) Adjusting screw.
Main Control Valve
(4) Tilt head end relief valve. (5) Tilt rod end relief valve. (6) Coupler head end relief valve. (7) Coupler rod end relief valve. (8) Main relief valve.1. Release hydraulic system pressure.2. Carefully loosen the tank fill cap to release any pressure in the tank. Tighten the cap.3. Install necessary fittings, connector, hose and pressure gauge in rod end line.4. Start the engine.5. With the attachment on the ground. Disengage the attachment until the coupler cylinder rods are fully retracted.6. Increase engine rpm to high idle, look at the test gauge and move the coupler control lever to the DISENGAGE position.7. The pressure setting of coupler rod end relief valve (7) should be 22 100 350 kPa (3210 50 psi). Do not keep the control lever in the DISENGAGE position, at the relief valve setting, more than 5 seconds.8. If the opening pressure of the relief valve is not to specification it will be necessary to adjust the valve.9.
