Cylinder, Hose, and Pump Repair for Hydraulic Systems of All Kinds
National Fleet Management repairs hydraulic systems on heavy-duty trucks, trailers, and equipment at our shops in Charlotte, Greensboro, Durham, and Statesville, NC - from a single hydraulic cylinder to a full hydraulic lift. Hydraulic systems power much of what a fleet vehicle does beyond driving: lifting, tilting, extending, and holding heavy loads under pressure, which means a failure in one component can shut down an entire piece of equipment even if the rest of the vehicle is running fine.
Because hydraulic systems rely on sealed pressure to function, even a small leak or worn seal can cascade into reduced performance, jerky operation, or a complete loss of lift capacity. NFM diagnoses hydraulic issues at the component level -cylinder, hose, fitting, or pump - rather than replacing parts by guesswork, so repairs address the actual point of failure and hold up under the next heavy-load cycle.
Signs of Hydraulic System Issues
- Slow or weak operation of a hydraulic lift, gate, or attachment
- Visible fluid leaks around cylinders, hoses, or fittings
- Jerky or inconsistent movement instead of smooth operation
- Loss of lift or lowering capacity under load

Frequently Asked Questions
What's the difference between a hydraulic leak and a hydraulic failure?
A leak is a symptom - fluid escaping from a seal, hose, or fitting. A failure means the system can no longer build or hold pressure properly, which can stem from a leak or from internal component wear, like a worn pump or cylinder.
What types of equipment rely on hydraulic systems?
Hydraulic systems power booms, lift gates, and material handlers, among other equipment - hydraulic repair supports many of NFM's other specialized services wherever a hydraulic component is involved.
