Hydraulic Pump and Cylinder Repair in Morris County NJ — Get Full Power Back in Your Hydraulic System

If your pump is running but not building pressure, the internal components are worn or damaged. A pump that makes unusual grinding or whining noises is telling you it needs attention. If your cylinder drifts down under load, meaning the bed drops slowly when you stop the pump, the internal seals are failing. Visible fluid leaking around the cylinder shaft is a clear sign that the seals need replacement. If the dump bed or lift gate moves slowly even though the motor sounds normal, the pump may have lost some of its capacity. A motor that runs but produces no movement at all could indicate a failed pump or a stuck valve. When multiple components fail at once, a full dump bed hydraulic service covers the entire system.

We start by diagnosing whether the problem is in the pump, the cylinder, the valve, or the lines. We test pump output pressure and flow to determine if the pump is performing within specification. For cylinder issues, we check for seal leaks, rod damage, and barrel scoring. Cylinder resealing involves pulling the cylinder, replacing all internal seals, inspecting the rod and barrel, and reinstalling. Pump repairs range from seal kits to full pump rebuilds depending on the internal wear. If a component is beyond repair, we source and install a replacement matched to your system specifications. After repair, we test the complete system under full load. We inspect every connection during a rebuild and handle hydraulic hose and fitting replacement as needed.

Costs vary based on the component and the repair type. A cylinder reseal is less expensive than a full cylinder replacement. A pump rebuild falls between a simple seal repair and a complete pump replacement. The size and capacity of the system affect parts costs.
