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.
Swing, travel and drive assemblies
Noise from a travel reduction gear, or metal on the drain plug, has three usual sources.
Boom, arm and cylinder functions
A function that moves smoothly at speed but stutters when the lever is barely open is fighting friction or air, not power.
Pump and pressure supply
Case drain flow shows how worn a pump or motor is without removing it.
Boom, arm and cylinder functions
When travel, swing, boom and bucket are all slow, the fault sits upstream of the individual circuits.
Oil, filtration and the system as a whole
In low ambient temperatures the oil is the problem, not the pump.
Oil, filtration and the system as a whole
In high ambient temperatures the hydraulic system runs near its thermal limits.
