New Title

International diesel engines run medium-duty trucks, school buses, delivery fleets, utility vehicles, and commercial equipment across North America. When one goes down, getting the right replacement fast matters — and "close enough" isn't good enough in a commercial operation. Pilot Engines remanufactures International diesel engines across the DT, MaxxForce, and legacy T-series lineups, matched to your engine serial number so the replacement drops straight in.

Every engine is fully remanufactured using OE parts, and every part is inspected before assembly. Drop-In engines are dyno tested. Long Block and Long Block Supreme engines are SIM tested. That means each unit ships ready to perform to OEM spec — not just to pass an inspection.

Match your engine serial number to the right build — that's step one. From there, round-trip freight is prepaid within the continental US, and your replacement is on its way. In-stock units ship immediately; most others are ready within 7–10 business days. Pilot Engines also buys cores, so your old International engine has value when it comes out.
