Navistar MaxxForce DT 9 10 G2.9 Injector | 5010715R91 | Torque Diesel | Remanufactured

Torque Diesel remanufactured G2.9 HEUI fuel injector for 2010–2014 Navistar MaxxForce DT, MaxxForce 9 and MaxxForce 10 engines rated 215 to 300 HP. Navistar references this injector as 5010715R91, 1890055C92 and 1890056C2. Installation requires removal of the high-pressure oil rail — plan on a rail seal kit as part of the job. Every unit is completely disassembled, inspected, and 100% end-of-line tested to OEM specification.

Fitment gate — this is the G2.9 generation injector for the 2010–2014 EPA10 platform. Earlier DT466E, DT530 and pre-EPA10 MaxxForce engines use different injector generations that do not interchange. Confirm your model year and engine before ordering.

Second fitment gate — read the part number off the injector you are removing and match it, or confirm your engine serial number, before ordering a full set.

Installation requirement — replacing these injectors requires removal of the high-pressure oil rail. Order a high-pressure oil rail seal kit to reinstall the rail. The job cannot be completed without it.

Conclusion

This is a Torque Diesel remanufactured G2.9 HEUI injector for 2010–2014 Navistar MaxxForce DT, MaxxForce 9 and MaxxForce 10 engines. Full disassembly, 100% nozzle replacement, and end-of-line testing to OEM specification restore the fuel atomization and delivery the engine depends on. Order a high-pressure oil rail seal kit alongside it, since the rail must come off to install these injectors.
