Heavy equipment, over-the-road trucks, and everything in a working fleet. If it runs on diesel and it's stopped, it's our job.
Mobile diesel repair
Full repairs performed on site. Engine, fuel, aftertreatment, air, and driveline work without a tow bill.
Heavy equipment repair
Dozers, excavators, loaders, skid steers, and haul trucks — undercarriage to cab.
Hydraulic system repair
Cylinders, pumps, valves, and hose failures diagnosed under load and rebuilt or replaced.
Electrical diagnostics
Charging faults, parasitic draws, harness damage, sensors, and starting systems traced to the wire.
Engine diagnostics
Laptop diagnostics, live data, and derate or fault-code troubleshooting on modern emissions engines.
Cooling system repair
Overheating diagnosis, radiators, water pumps, fan drives, and coolant leaks in summer heat.
Brake & suspension repair
Air and hydraulic brakes, slack adjusters, springs, and steering components inspected and replaced.
Welding & fabrication
Cracked buckets, broken brackets, custom mounts, and structural repairs welded in the field.
Fleet maintenance
Service intervals tracked across your whole fleet, with records you can hand to a DOT inspector.
On-site breakdown assistance
Emergency response when a machine or truck stops where it sits. We come to the equipment.
Fleet service agreements
