Pilot controls are slow unless another joystick is moved: what should be checked?
Short Answer
Slow pilot-control functions that improve when another joystick is moved usually point to a pilot supply, shuttle, relief, valve spool, or control-signal problem rather than one bad cylinder. JIAJUE checks pilot pressure behavior and valve response before quoting pumps, joystick valves, or solenoids.
What To Check
- Compare pilot pressure at neutral, single-function operation, and combined-function operation.
- Inspect pilot filter, accumulator, pilot relief, joystick valve outputs, shuttle valves, and sticking main spools.
- Send valve-bank photos, pilot-line routing, machine model, serial number, and any visible part numbers before ordering.
