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.
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.
Cylinder drifts down under load
Boom, arm and cylinder functions
Drift is a leakage question. These checks tell you whether oil is passing the piston seal, the control spool or the holding valve…
Foam or milky hydraulic oil
Oil, filtration and the system as a whole
Foam means air, milkiness means water, and both destroy the lubrication film.
Spools stick or lock when cold
Valve and pilot control
A spool that sticks when cold, or grabs in one position, is telling you about oil cleanliness, varnish or bore damage.
Machine weak when it is hot
Oil, filtration and the system as a whole
In high ambient temperatures the hydraulic system runs near its thermal limits.
