Diesel engines. Diagnosed deeper. Rebuilt right.
Engine problems need more than parts swapping. TractoAuto combines electronic diagnostics, mechanical testing, repair, programming and verification for modern heavy-duty diesel platforms.
Mack E7 diagnostics, repair and overhaul.
Real-world Mack E7 service focused on mechanical condition, cylinder-head work, internal engine repair, turbo and air systems, fuel delivery and complete overhaul planning.
Caterpillar engine work built around fundamentals.
Diagnostics and repair for Caterpillar heavy-duty platforms, including block and cylinder-head work, internal inspection, overhaul assembly, turbo systems and fuel-system integration.
PACCAR MX diagnostics and mechanical repair.
PACCAR faults can overlap between fuel pressure, air management, turbo operation, sensors, harnesses and ECM strategy. We test the system before recommending repairs and verify the result after the work is complete.
Cummins engine diagnostics through major repair.
From performance and fuel-system concerns to top-end work, turbo and air-management faults, internal mechanical failures, in-frame service and complete overhaul work.
Real work from teardown to final assembly.
A complete engine repair is a sequence of inspection, measurement, component preparation, controlled assembly and final verification — not a single parts replacement.
