Information:
Implement Control Valve Group (machine with blade power angle shown) (Later Style Shown)
(1) Rod end of left cylinder and head end of right cylinder relief valve. (2) Rod end of right cylinder and head end of left cylinder relief valve. (3) Lift rod end relief valve [on machines equipped with straight blade only].Bench Test
1. Lower all implements to the ground.2. Shut off the engine and move all the control levers to all positions. This releases system pressure.3. Relieve hydraulic tank pressure.4. Remove the relief valve to be tested.5. Install the relief valve in the 1U5216 Manifold.6. Connect the manifold to the hydraulic test bench.7. Slowly increase pressure. Note the pressure when the relief valve opens. Make an adjustment if needed.Relief Valve Adjustments
See the subject Relief valves when testing relief valves.
Typical Line Relief and Makeup Valve
(4) Cap. (5) Locknut. (6) Adjusting screw.1. Remove protective cap (4).2. Loosen locknut (5).3. Turn adjusting screw (6) clockwise for an increase. Turn adjusting screw (6) counter clockwise for a decrease in the pressure setting of the relief valve.4. After screw (6) is turned for an adjustment, tighten locknut (5) and re-test the adjustment.5. Install cap (4) after the adjustments are correct.Troubleshooting
Problem Checklist
Hydraulic Pump and System Problem List
1. The temperature of the oil is too hot.2. Pump makes unusual noise, the cylinder rods do not move smoothly and there are air bubbles in the oil.3. A large amount of air in the oil.4. Low pressure standby is too low.5. Low pressure standby is too high.6. Margin pressure too low.7. Margin pressure too high.8. Pump discharge pressure too high (high pressure stall).9. Pump discharge pressure too low (high pressure stall).10. There is a pause before pressure is reached in all circuits.11. Signal pressure is not zero (or tank pressure) when all valves are in HOLD.Implement System Problem List
1. Any implement moves with control lever in HOLD position.2. Control stem on valve does not shift into body.3. Too much implement drift.4. Implement droops when going from a partially raised position to a raised position.5. All implement cycle times too slow.6. Bulldozer blade floats up with control in HOLD when dozing.7. All implement cycle times are too fast.8. There is too long of a pause at ground level before the machine starts to raise.9. Line reliefs too noisy.Hydraulic Pump And System Problems
Problem 1: The temperature of the oil is too hot. Probable Cause:1. The viscosity of the oil is wrong. Make reference to the machine's Operation & Maintenance Manual.2. The pump has too much wear.3. There is a restriction in an oil passage.4. The load of the system is too high.5. Oil aeration.6. Low oil level.7. Flow compensator valve set wrong (margin pressure too high).8. Outside air temperature is too hot. Problem 2: Pump makes unusual noise, the cylinder rods do not move smoothly and there are air bubbles in the oil. Probable Cause:1. The viscosity of the oil is wrong. Make reference to the machine's Operation & Maintenance Manual.2. Loose connection of the oil line on
