Expert Motor Repair & Rewind Services

We repair and rewind all types of hydrostatic and hydraulic motors including fixed displacement motors, variable displacement motors, bent axis motors, orbital motors, and final drive motors. Our services cover motors used in excavators, heavy construction equipment, agricultural machinery, industrial equipment, material handling systems, and specialized applications. We service all major brands including Sundstrand, Eaton, Sauer-Danfoss, Rexroth, Kawasaki, Kobelco, and hundreds of other manufacturers. Whether you need a common production motor rebuilt or an obsolete unit remanufactured, we have the expertise and parts inventory to handle it.

This allows us to perform on-site diagnostics and repairs for equipment that's down at job sites, minimizing costly downtime. Our mobile units carry common replacement parts and specialized tools to handle many repairs in the field. For motors requiring shop-level rebuilding, we can quickly remove the motor on-site and provide exchange units to get your equipment operational while we remanufacture your original motor to factory specifications.

Our comprehensive motor rebuild service includes complete disassembly, inspection, cleaning, and assessment of all internal components. We replace worn seals, bearings, pistons, valve plates, and other damaged parts with genuine OEM-quality components. Each rebuilt motor undergoes precision testing using advanced diagnostic equipment to verify performance meets or exceeds manufacturer specifications. We perform calibration adjustments, pressure testing, and flow testing to ensure optimal operation. The rebuild includes new seal kits, overhaul kits, and any necessary internal components, all backed by our 1-year warranty.

Motor repair and rebuild services typically cost 40-60% less than purchasing a new replacement motor, delivering significant savings while restoring performance to OEM specifications. Exact costs depend on motor type, size, manufacturer, extent of damage, and parts requirements. We provide free quotes after assessing your motor's condition. For many applications, our exchange program offers the most cost-effective solution—you receive a remanufactured motor immediately while we rebuild your core, avoiding both new motor costs and extended downtime expenses.
