KIT-WASHER 2232321 - Caterpillar

Recommendation For Action:
Do the Blocked Cylinder Test for cylinders on the right side.Problem: Tests 27 through 32 give an indication of leakage in the control valves.
Probable Reason:
A. Leakage in the relief valve for maximum pressure.B. Leakage in the make-up valves in all circuits.C. Wear or damage in the valve body and spools.Recommendation For Action:
Problem is in the control valves. Remove the units and inspect their components.Problem: Tests 27 and 28 give an indication of leakage in lift control valve.
Probable Reason:
A. Leakage in both make-up valves for the lift circuit.B. Wear or damage in the body and spool for the control valve in lift circuit.Recommendation For Action:
Problem is in the lift control valve. Remove this unit and inspect its components.Problem: Tests 29 and 30 give an indication of leakage in the tilt control valve.
Probable Reason:
A. Leakage in both make-up valves for the tilt circuit.B. Leakage in both tilt relief valves.C. Wear or damage in the body and spool for the control valve in the tilt circuit.Recommendation For Action:
Problem is in the tilt control valve. Remove this unit and inspect its components.Problem: Tests 31 and 32 give an indication of leakage in the auxiliary control valve.
Probable Reason:
A. Leakage in the make-up or relief valves for auxiliary control valve.B. Wear or damage in the body and spool for the control valve in auxiliary circuit.Recommendation For Action:
Problem is in the auxiliary control valve. Remove this unit and inspect its components.Right Side Cylinders Blocked
If the Blocked Cylinder Tests gives an indication of leakage that is too high in one or more of the cylinders, do the Blocked Cylinder Tests for the Right Side. For best accuracy, operate all controls through several cycles to get the temperature of the oil in the cylinders the same as the temperature of the oil in the hydraulic tank. Make the temperature of the complete system 150° F.Lower all implements to the ground. Stop the diesel engine. Move the control levers through OPERATE and HOLD positions to release any oil pressure. Put the control levers in HOLD position. Open the filler cap for the hydraulic tank to release any tank pressure and close the cap. Use the Blocking Plate Assemblies, to block the rod end of the right lift cylinder, head end of the right tilt cylinder and the rod end of the right auxiliary cylinder as needed.Test 34: System Oil Temperature (Oil Temperature of the System)
Open the load valve fully. Start the diesel engine. Run the engine at any rpm with the system pressure at 0 to 100 psi. Move control lever to LOWER position. Write down the oil temperature. Tests 35 through 37 are Leakage Rate Tests.Test 35: Lift Lower Flow Rate (Flow Rate in Lift Lower)
With the load valve fully open, move control lever to LOWER
