Heavy truck & semi repair

Class 7–8, fleet, and over-the-road diesel trucks — kept running and DOT-ready, in the shop in Eolia or mobile across Pike County.

When a truck is down, it's not making money. Pike County Truck & Tractor Repair keeps heavy diesel trucks and semis on the road with straight diagnosis and dependable repairs — whether you run one truck or a small fleet. Bring it to the shop, or we'll come to your yard or the roadside.

What we handle

  • Engine diagnostics & driveability — hard starts, power loss, check-engine and fault codes
  • Air systems & brakes — compressors, valves, lines, slack adjusters, chambers
  • After-treatment — DPF, DEF, and EGR diagnosis, cleaning, and repair
  • Electrical & charging — batteries, alternators, starters, lighting, wiring
  • Cooling, belts, hoses, and preventive maintenance / PM service
  • Clutch, driveline, suspension, and steering work
  • DOT-related repairs to get you back in compliance

Fleet & owner-operators

Running on a schedule? We'll work with owner-operators and small fleets on preventive maintenance so the breakdowns happen a lot less often. One mechanic who knows your trucks — not a rotating door of techs.

Shop or mobile

Some jobs are best in the shop; some you can't move. We do both — on-site service for trucks that can't roll, and full repairs back at the shop in Eolia. Broke down right now? Call and we'll come to you.
