Light, medium, and heavy equipment, and everything else 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, powertrain, hydraulics, and aftertreatment systems — 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 handled in the field.
Fleet maintenance
Standing service schedules across every unit you run, so intervals get caught before they turn into downtime.
When equipment goes down, we come to you
Our mobile service gets to the jobsite, diagnoses the problem, and works to get your equipment back up and running.
Fleet service agreements
Standing schedules and priority dispatch for operations running ten or more pieces.
