Used International Engines for Sale

Our used International engines for sale cover several generations of medium-duty, bus, vocational, and Class 8 power. Current identified inventory includes the mechanical DT466, electronic DT466E, T444E V8, VT365 V8, MaxxForce 7 V8, MaxxForce DT inline-six, and MaxxForce 13 inline-six. These engine families powered International medium-duty trucks, DuraStar and 4000-series applications, school buses, dump and utility trucks, delivery equipment, and heavier highway or vocational trucks. They share an International or Navistar badge, but they do not share one installation. Displacement, cylinder configuration, fuel system, electronics, emissions equipment, mounts, cooling, and accessory layouts vary substantially across the model range.

The DT466 family is especially important to identify correctly. Earlier DT466 engines use mechanical injection, the DT466E uses electronic HEUI controls, and the later MaxxForce DT represents an emissions-era electronic evolution of the 7.6-liter family. The T444E is a 7.3-liter V8, while the VT365 is a 6.0-liter V8 and the MaxxForce 7 is a 6.4-liter V8. The MaxxForce 13 is a much larger 12.4-liter Class 8 engine. These distinctions affect chassis fitment, wiring, ECM calibration, fuel-system components, exhaust and aftertreatment equipment, flywheel housings, and accessories. The model hubs below use real catalog inventory and list each matching engine by year and stock number so buyers can compare actual units rather than broad family names.

Buying a tested used International engine can keep a working truck or bus in service while avoiding the cost and delay of replacing the complete vehicle. Machinery & Truck Parts inspects and tests used engines before shipping, includes warranty coverage, and supports buyers from our Rockwood, Tennessee shop. Nationwide freight is available and quoted to the destination ZIP code. Condition still needs to be considered alongside fitment, so review the listing photos and ask what accessories, ECM, turbocharger, manifolds, air compressor, flywheel housing, and emissions components are included with the specific stock number.

Before ordering, gather the truck or bus year, make, model, VIN or application, engine serial number when available, and the stock number of the engine you are considering. For MaxxForce engines, also confirm the emissions generation and aftertreatment configuration. For DT466 and DT466E engines, confirm whether the original application is mechanical or electronic instead of relying on the 466 designation alone. Careful identification reduces avoidable downtime and freight complications. Call (800) 696-5459 with those details and the delivery ZIP code. The parts team can review current availability, help confirm the closest fit, explain warranty terms, and prepare a nationwide freight quote.
