International Harvester

PDM machines and rebuilds International Harvester engines from tractors and farm equipment.

What we do with them

International Harvester engine machining

International Harvester work is mostly restoration-adjacent: equipment old enough that new parts are scarce and a machined repair is the practical answer rather than the sentimental one.

That makes inspection matter more, not less. Magnaflux magnetic-particle inspection and pressure testing find the cracks that decide whether a casting is worth the machining before the machining is paid for.

Where these engines turn up

Agricultural tractors, farm equipment and older trucks.
