Common faults on this machine, 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.
Proportional pilot control reacts late, in steps, or not at all
Valve and pilot control
Machines with proportional pilot control fail in a characteristic way: the function arrives late, arrives in steps, or does not…
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.
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.
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.
