Common faults on this unit, and what to check first
The diagnosis guides below start from the symptom, list the checks in the order a workshop should work through them, and say which parts usually solve it. Full index: diagnosis guides.
No pressure / no power at the pump
Pump and pressure supply
No pressure is rarely the pump alone. Use this checklist to separate pump wear from control, suction and relief problems in under…
Noise, vibration and rising oil temperature
Pump and pressure supply
Noise plus heat usually means air, starvation or internal leakage. Which one you have changes what you order.
Case drain flow above specification
Pump and pressure supply
Case drain flow shows how worn a pump or motor is without removing it.
Engine stalls or smokes under load
Pump and pressure supply
When the engine pulls down, the pump is usually asking for more torque than the engine can deliver.
Oil temperature keeps rising
Oil, filtration and the system as a whole
Over-temperature thins the oil and shortens seal life, so every function weakens.
Metal particles, dirty oil, short component life
Oil, filtration and the system as a whole
Contamination is the number one cause of repeat failures. Here is what to do after a failure so the new pump is not destroyed by…
