This is the Alliant Power AP0026, a new seal kit for one G2.9 injector. Alliant lists it for the 2004 to 2006 International DT466, DT570 and HT570, the 2007 to 2014 MaxxForce DT, 9 and 10, and the 2015 to 2017 N9 and N10. It replaces International 1842624C92.
Alliant’s picture of the kit shows two seal rings and one chamber gasket. That is the same set Alliant lists in the box with one of its remanufactured G2.9 injectors, so this kit is for injectors you are taking out and refitting.
The high-pressure oil rail has to come off to reach these injectors. Its seals are a separate kit, Alliant Power AP0025.
Confirm Fitment Before You Order
This kit is for G2.9 injectors on the engines named on this page. It is not for the 1994 to 2003 DT466E, I530E or DT530, which take the HEUI seal kit AP0001. Send us your engine serial number if you are not sure which injector you have. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.
