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.
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.
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.
Tracks weak, one side not moving
Swing, travel and drive assemblies
A travel fault looks expensive, but the checks are cheap. Work through them in this order before ordering a travel drive assembly.
Final drive noisy or metal in gear oil
Swing, travel and drive assemblies
Noise from a travel reduction gear, or metal on the drain plug, has three usual sources.
Movement stutters or crawls when the lever is barely open
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.
