Symptom-first troubleshooting
Diagnose My Hydraulic Cylinder
Describe what the cylinder is doing. The tool ranks plausible causes and gives targeted checks so you can avoid replacing seals before confirming the fault.
A pressure reading under load is more useful than a no-load reading.
Hydraulic systems can retain dangerous stored pressure. Support loads, isolate energy and relieve pressure before opening the circuit or cylinder.
Need help interpreting the result?
Email the symptom, what you have already checked, and any known pressure/flow information. HydraResolve is not an emergency service.
Bring measurements to the repair decision
Compare theoretical force and travel time with your records, then print the results and repair observations. The worksheet accounts for back pressure and shows every assumption.
