This is the Alliant Power AP63697, a 16cc high-pressure oil pump (HPOP) remanufactured by Alliant Power for the 2007 to 2010 International / Navistar MaxxForce 9 and MaxxForce 10, engine serial numbers 3,040,001 through 3,300,000. It replaces Navistar 1882259C93, 1832094C92, 1832095C2, 1879745C93 and 1879747C2, and it took over from the earlier Alliant Power number AP63687. It comes with a new injection pressure regulator (IPR) valve, Alliant Power AP63513, and the fuel supply pump.
The injectors on these engines are fired by high-pressure oil, and this pump makes that pressure. When it wears, the engine cranks long, will not restart hot, stalls, or sets low injection control pressure (ICP) faults. Rule out oil leaks at the hose, the rail and the injector seals first. This is the 16cc pump for the MaxxForce 9 and MaxxForce 10. The MaxxForce DT takes the 12cc pump, AP63696.
Confirm Fitment Before You Order
Order by engine serial number, not by the number on your old pump: Navistar 1882259C93, 1832094C92 and 1832095C2 are also listed for the early-engine kit, AP63695. This pump covers 3,040,001 to 3,300,000. Engines from 3,000,001 to 3,040,000 take that kit, which adds the updated high-pressure hose and fitting, and engines from 3,300,001 take a different pump. Send us your engine serial number before you order. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.
