Can hydraulic motors be repaired?
Yes, hydraulic motors can be fully repaired and rebuilt. At Hydrostatic Transmission Service, we disassemble, clean, measure, and recondition all internal components — including displacement valves, seals, and manifolds — to original manufacturer specifications. After rebuilding, every motor is pressure- and flow-tested before shipment. All rebuilt hydraulic motors come with a 1-year warranty.
What brands of hydraulic pumps and motors do you rebuild?
We rebuild hydrostatic pumps, motors, and drives from a comprehensive range of manufacturers, including Kawasaki, Rexroth, Parker, Eaton, Vickers, Danfoss, Sundstrand, Komatsu, Uchida, Hydromatik, Brueninghaus, Cessna, Linde, Hitachi, Mitsubishi, Volvo, John Deere, Sauer Danfoss, and many more. If you don't see your brand listed, contact us — we likely service it.
How long does a hydraulic rebuild take?
Standard rebuild turnaround depends on the unit's complexity and parts availability, but we offer a Short-Time Exchange Program to eliminate waiting. We ship a quality-tested, fully warranted rebuilt unit immediately while your original core is being processed, dramatically reducing downtime for your operation.
Do rebuilt hydraulic units come with a warranty?
Yes. Every hydrostatic pump, motor, and drive rebuilt by Hydrostatic Transmission Service comes with a full 1-year warranty. Units are rebuilt and tested to manufacturer specifications using our Statistical Process Control System, ensuring each unit meets quality benchmarks before it leaves our facility.
What is the exchange program and how does it work?
Our Short-Time Exchange Program allows you to receive a fully rebuilt, quality-tested, and warranted replacement unit quickly — before your original core is even fully evaluated. Simply contact us with your unit details, and we'll ship a compatible rebuilt replacement from our inventory, minimizing expensive equipment downtime.
