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.
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…
Hoses burst, seals blow, the gauge needle jumps
Valve and pilot control
Hoses failing in the same place, filters splitting or a gauge needle that jumps are transient problems.
Machine slow or noisy when cold
Oil, filtration and the system as a whole
In low ambient temperatures the oil is the problem, not the pump.
All functions slow
Boom, arm and cylinder functions
When travel, swing, boom and bucket are all slow, the fault sits upstream of the individual circuits.
