Our Mobile Heavy Equipment Repair Capabilities

Leave your on-site service to our expert technicians. We have a wide range of heavy equipment field service capabilities, including common services such as:

Engine Service

Many clients request engine service on-site because a malfunctioning engine makes it difficult to get a machine to the shop. We can repair or replace parts from Cat® engines and other engine makes. Our technicians work with standard fuel engines, diesel engines, and engines for power supply systems. As part of the Caterpillar network, we have access to parts for a variety of engines.

Hydraulics Repairs and Maintenance

Hydraulics maintenance and repairs also happen at many of our field visits. Regular hydraulic system service keeps your equipment running smoothly due to the system’s importance to performance. Our diagnostic systems can pinpoint any issues with your hydraulics, allowing us to make repairs right away.

Welding and Fabrication

Our on-site technicians can perform select types of welding and fabrication at your job site. In most cases, these jobs involve repairing or replacing a part of your equipment. We can remake or weld simple components to get your equipment running again. Since our technicians have factory training for welding and machining, they will provide durable and high-quality results.

Oil Sampling

Depending on your service area, you could have the option to request fluid sampling for preventive maintenance. When you join our S.O.S. Fluid AnalysisSM program, our technicians will take regular samples of your equipment’s oil. They will then take the sample to our Nashville analysis lab to check for abnormal wear trends. Proactive oil sampling allows you to find potential problems before they become major issues.

Undercarriage Service and Repairs

Your machine’s undercarriage goes through wear and tear that you might not notice at first glance. As part of our field maintenance service, our technicians check the undercarriage’s integrity and alignment. They can perform repairs on any cracks and correct alignment problems to get your equipment working in top shape.

Thompson Machinery clients get field service from our technicians for reasons such as:

  • Convenience: Field service allows you to keep working while we come to your job site to complete maintenance or repairs.
  • Speed: When you can’t afford to have out-of-service equipment for long, our field team can get it working again quickly.
