Our Cat® Certified Hydraulic Repair Process
Thompson Machinery takes the guesswork and the risk out of hydraulic repairs. Following processes set by Caterpillar, here’s how we ensure quality and performance:
- Complete disassembly and inspection: Before your pump or hydraulic motor repair, every component is carefully disassembled and cleaned in a contamination-controlled environment. Our certified technicians perform thorough failure analysis to identify root causes, not just symptoms.
- Genuine parts and precision rebuild: All worn or damaged parts are replaced with genuine Cat or OEM components. Major assemblies are precision-honed and reconditioned to original factory specifications for a perfect fit and reliable function.
- Performance and pressure testing: After reassembly, every pump or motor is mounted to a hydraulic test bench and operated under simulated working conditions. We only return units that meet or exceed original efficiency and pressure standards, so your equipment delivers like-new performance.
The Benefits of a Professional Hydraulic Pump or Motor Rebuild
When an unexpected hydraulic pump or motor failure knocks out your machine, many owners feel forced to buy new components. But that often comes with higher costs and longer lead times. Our hydraulic repair and rebuild services are designed for fleet managers and business owners who cannot afford unnecessary delays or runaway expenses.
There are many benefits to choosing to rebuild instead of replace, including:
- Significant cost savings: A professional hydraulic pump or motor rebuild typically costs significantly less than purchasing brand-new. That’s money you keep in your operating budget to reinvest where you need it most.
- Faster turnaround and less downtime: Waiting days or even weeks for new parts can stall entire projects and stress client relationships. Our Cat-certified repair process gets you back to work faster, restoring components usually in less time than it takes to source replacements.
- Restored, like-new performance: We use only genuine Cat parts, following strict factory specs and verifying results with advanced hydraulic testing so you get the power, reliability and efficiency of a like-new machine — without the price tag.
