Engine & Powertrain Refresh

A full mechanical rebuild of the heart of the truck — the engine and the systems that let it breathe, spark, cool, and deliver power. This service is for rigs with solid bones that need their drivability, efficiency, and reliability restored. The engine comes out, every supporting system is serviced, and the powertrain goes back in tight, clean, and ready for years of use.

  • Gaskets and seals replaced throughout
  • Head inspection and service if needed (valve seals, seats, surface)
  • All mounts, hardware, and brackets cleaned and replaced as needed

  • Intake system cleaned and checked for vacuum leaks

Ignition & Timing

  • New plugs, wires. Cap and rotor cleaned or replaced
  • Ignition Coil tested and replaced if necessary
  • Distributor inspected and advanced/retarded to spec

Driveline Interface

Testing & Final Checks

Every engine is heat-cycled, oil pressure verified, and ignition timing set under load. Cooling, charging, and fuel systems are pressure-tested and documented before delivery. The result is a clean engine, and a truck that starts, runs, and drives like it should.

 

Result:
 A tight, tuned powertrain — smooth idle, clean throttle response, no smoke, no guesswork. Just an honest, reliable Land Cruiser tractor engine doing what it was built to do.
