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.
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.
Repair the pump or replace it
Oil, filtration and the system as a whole
The decision follows measurable evidence, not the age of the machine.
No pressure / no power at the pump
Pump and pressure supply
No pressure is rarely the pump alone. Use this checklist to separate pump wear from control, suction and relief problems in under…
Noise, vibration and rising oil temperature
Pump and pressure supply
Noise plus heat usually means air, starvation or internal leakage. Which one you have changes what you order.
Case drain flow above specification
Pump and pressure supply
Case drain flow shows how worn a pump or motor is without removing it.
