Motor repair costs vary significantly based on motor type, size, manufacturer, and damage extent. Hydrostatic motor rebuilds typically range from $1,500 to $8,000 depending on the unit. Excavator drive motors generally cost $2,500-$6,000 to rebuild, while smaller tractor or industrial motors may range $1,200-$3,500. Final drive motor repairs including gear assemblies run $3,000-$10,000.

Our comprehensive motor repair includes complete teardown and inspection, precision cleaning of all components, replacement of worn bearings and seals, machining or replacement of damaged internal parts, reassembly to OEM specifications, and performance testing on calibrated equipment. You'll receive a detailed test report documenting flow rates, pressure ratings, and operational efficiency. All repairs include new seal kits, necessary internal components, final calibration, and our 1-year warranty covering parts and workmanship.

Standard motor repair turnaround is 5-10 business days from receipt of your unit to shipping of the rebuilt motor. Most repairs ship within 3 days for common motor models where we maintain parts inventory. Complex rebuilds requiring specialized components or custom machining may take 2-3 weeks. For critical applications, we offer exchange programs where we ship a remanufactured motor immediately while your core is rebuilt. Emergency rush service is available for urgent situations—contact us to discuss expedited options for your specific timeline.

Yes, every motor repair is backed by our comprehensive 1-year warranty covering parts and workmanship. This warranty protects against defects in rebuilt components, seal failures, and performance issues related to our rebuild work. We also offer a full money-back guarantee if the repaired motor doesn't meet OEM performance specifications. The warranty covers the motor unit itself; installation labor and consequential damages are excluded. Warranty claims are processed quickly with replacement units shipped at no charge for valid warranty issues.

We repair all types of hydrostatic and hydraulic motors including fixed displacement motors, variable displacement motors, bent axis motors, axial piston motors, orbital motors, and radial piston motors. Our expertise covers excavator drive motors, final drive motors, tractor transmission motors, industrial machine motors, and specialized equipment motors. We service major brands including Sundstrand, Eaton, Sauer-Danfoss, Danfoss, Kobelco, Kawasaki, Komatsu, Rexroth, Vickers, and Parker. If you have an unusual or obsolete motor, contact us—we maintain an extensive parts network for hard-to-find units.

Absolutely. We specialize in repairing motors for older and obsolete equipment where parts are no longer manufactured. Our extensive supplier network and reverse-engineering capabilities allow us to source or fabricate components for discontinued motor models. We maintain technical documentation and rebuild specifications for legacy motor series from Sundstrand, Eaton, and other manufacturers dating back decades. Many operators rely on us specifically because we can repair motors that other shops turn away due to parts availability challenges. Contact us with your motor model details for a feasibility assessment.

Yes, we understand equipment downtime costs money. For emergency situations, we offer expedited repair services with priority processing and faster turnaround. Our exchange program provides the fastest solution—we ship a remanufactured motor immediately while your core is rebuilt and returned. We maintain inventory of common excavator, tractor, and industrial motors for immediate exchange. Rush repairs typically add 15-25% to standard pricing depending on urgency level. Contact us at 800-361-0028 to discuss your emergency situation and we'll work to minimize your downtime.

For an accurate quote, provide the motor manufacturer name (Sundstrand, Eaton, etc.), model number or series (usually stamped on the motor nameplate), and a description of the problem or symptoms you're experiencing. Photos of the motor nameplate and any visible damage are helpful. If possible, note the equipment type where the motor is installed (excavator model, tractor model, etc.). Details about fluid leaks, loss of power, unusual noises, or overheating help our technicians assess repair scope.
