[Call Now 973-651-1045](tel:9736511045)[Get Free Estimate](/contact) 30+ Years Experience Family Owned & Operated Mobile Service to Your Door Only High Quality Parts Your hydraulic pump builds the pressure that powers everything. Your cylinders convert that pressure into the force that lifts your dump bed or operates your lift gate. When either one fails, your hydraulic system cannot do its job. Keep Them Rolling Trailer Repair provides mobile hydraulic pump and cylinder repair across Morris County NJ. We diagnose the problem and repair or rebuild the failed component right at your location. ## When You Need Hydraulic Pump or Cylinder Repair 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](/dump-trailer-hydraulic-system-service) covers the entire system. ## Our Hydraulic Pump and Cylinder Repair Process 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](/hydraulic-line-repair) as needed. ## Hydraulic Pump and Cylinder Repair Cost in Morris County 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. We always diagnose first and present your options with clear pricing before we start any work. No hidden fees. Fleet customers with 3 or more trailers receive a 10% discount on every service call. ## Why Choose Keep Them Rolling We have over 30 years of experience working on trailer hydraulic systems.
