Can a seized water pump be fixed?
Yes, a seized pump can often be repaired rather than replaced. Our technicians disassemble the unit, inspect the shaft, bearings, seals, and internal components for corrosion or mechanical damage, then recondition or replace the affected parts. As long as the housing and core structure are intact, most seized pumps can be fully rebuilt to manufacturer specifications and returned to service with a 1-year warranty.
What brands of hydrostatic pumps and motors do you repair?
We repair and rebuild a wide range of brands including Kawasaki, Rexroth, Eaton, Parker, Danfoss, Sundstrand, Vickers, Uchida, Komatsu, Hitachi, Mitsubishi, Linde, Hydromatik, Brueninghaus, Cessna, Volvo, John Deere, Sauer Danfoss, and many more. If your brand isn't listed, contact us — our technicians have experience with virtually all major hydrostatic manufacturers.
How long does a hydrostatic pump or motor rebuild take?
Standard rebuild turnaround depends on the unit's condition and parts availability, but most rebuilds are completed efficiently in our facility. To minimize downtime immediately, we offer a Short-Time Exchange Program — we ship a fully tested, warranted rebuilt replacement unit while we service your core, getting your equipment back in operation as quickly as possible.
What does the rebuild process include?
Our full rebuild process includes pressure washing, disassembly, solvent cleaning in a reduced-dust environment, precision measurement against OEM specs, valve and manifold rebuilding, reconditioning or replacing all worn parts, leak testing, pressure and flow calibration, fresh paint, oil fill to prevent shipping condensation, and a quality warranty seal — all backed by a 1-year warranty.
Do rebuilt units come with a warranty?
Yes. Every hydrostatic pump, motor, or drive rebuilt or exchanged by Hydrostatic Transmission Service comes with a full 1-year warranty covering parts and workmanship. This warranty applies to all brand-specific rebuilds as well as units provided through our exchange program, giving you confidence in every unit we deliver.
Do you offer an exchange program to reduce downtime?
Absolutely. Our Short-Time Exchange Program is specifically designed to minimize operational downtime. We ship a quality-tested, fully warranted rebuilt replacement unit to you quickly, covering major brands including Kawasaki, Eaton, Rexroth, Sundstrand, Vickers, Parker, and more. This allows your equipment to return to service while we rebuild your original core.
Do you buy surplus hydraulic and hydrostatic parts?
Yes. We actively purchase surplus hydraulic cores, hydrostatic cores, and surplus pumps, motors, and parts from brands such as Sundstrand, Eaton, Rexroth, Kawasaki, Vickers, Uchida, Komatsu, and others. We pay top price for quality core parts. Contact our team at sales@htsrepair.com or call (800)-361-0068 to discuss your surplus inventory.
Do you provide installation support after a rebuild or exchange?
Yes. Our trained technicians offer an Installation Advice Service to help you correctly install and maintain your rebuilt or exchanged hydrostatic unit. Proper installation is essential for longevity and performance, and our team is available to walk you through the process, whether you're dealing with a drive, pump, or motor in an industrial or heavy equipment application.
