What types of hydraulic pumps can Hydrostatic Transmission Service repair?
We rebuild and repair a wide range of hydraulic and hydrostatic pumps, motors, and drives from over 30 brands including Rexroth, Kawasaki, Eaton, Parker, Vickers, Danfoss, Sundstrand, Komatsu, Hydromatik, Brueninghaus, Cessna, Uchida, and more. Both piston and gear-type units are serviced and rebuilt to OEM specifications.
What does the hydraulic pump rebuild process include?
Our rebuild process includes pressure washing and full disassembly, solvent cleaning in a reduced-dust environment, precision measurement of all components against manufacturer specs, valve rebuilds, charge pump reconditioning, high-pressure manifold inspection, new seals and O-rings, leak testing, pressure and flow calibration, and a final quality seal and paint job. Every unit is backed by a 1-year warranty.
How long does a hydraulic pump rebuild take?
Standard rebuild turnaround times vary depending on the unit type and parts availability. To minimize downtime, we offer a short-time exchange program where a pre-rebuilt, quality-tested, and fully warranted replacement unit is shipped quickly while your original unit is being rebuilt. Contact us to discuss your specific timeline requirements.
Do rebuilt hydraulic pumps come with a warranty?
Yes. Every hydraulic pump, motor, or drive rebuilt by Hydrostatic Transmission Service comes with a full one-year warranty. This applies to all brands we service and covers units processed through both our standard rebuild program and our short-time exchange program.
What is the exchange program and how does it reduce downtime?
Our exchange program ships a quality-tested, fully warranted rebuilt replacement unit in 'short-time' so your equipment is back in service as quickly as possible. We accept your defective core unit in exchange and cover brands including Kawasaki, Eaton, Rexroth, Vickers, Sundstrand, Komatsu, Hitachi, Volvo, and many more.
Does Hydrostatic Transmission Service supply hydraulic parts internationally?
Yes, we supply hydrostatic and hydraulic parts internationally. Our inventory includes new and used components, plus hard-to-find parts for Parker, Eaton, Vickers, Rexroth, Kawasaki, Danfoss, Sundstrand, Cessna, Brueninghaus, and Uchida. We also purchase surplus hydraulic and hydrostatic inventory and pay top price for core parts.
Can you provide installation advice after a pump is rebuilt?
Absolutely. Our technicians are trained in the installation of hydrostatic drives, pumps, and motors and offer a dedicated installation advice service. Whether you're reinstalling a rebuilt unit or setting up a replacement, our team can guide you through proper installation and maintenance procedures to ensure peak performance and longevity.
How are hydraulic pumps tested to ensure quality after rebuilding?
Each rebuilt unit undergoes testing using our dedicated testing apparatus to verify there are no leaks and that all parameters meet specification. We use a Statistical Process Control System to record and compare quality data against OEM standards. Pressure and flow adjustments are made as needed before the unit is sealed, painted, and shipped with a warranty.
