This is the Alliant Power AP66992, a remanufactured G2.9 BANG fuel injector for the International DT570 9.3L. Catalogs list it for the 2006 model year engine at 285 to 330 hp. PurePower Technologies, which remanufactures it for Alliant Power, calls it the 5LB injector, 6927-PP, the low horsepower injector for the 570 engines of model year 2005.5 to 2007. It replaces Navistar 1848492C91, 1848492C92 and 5010984R91.

BANG is the name catalogs use for the later G2.9 injector that took over from the 2004 to 2005 injectors partway through 2005. The 9.3L engines got two of them: this one for the DT570, and AP66995 for the HT570, the high torque engine at 295 to 340 hp. The ratings overlap, so go by the engine model, not the rating alone. The earlier 2004 to 2005 DT570 takes AP66978, and the 2007 to 2010 MaxxForce 9 and 10 take AP66921. Alliant Power lists new connectors, spool valve, coil and harness assemblies on this injector. The engine takes six.

Specifications

Fits / Applications

• International DT570 9.3L, 2006 model year, 285 to 330 hp
• PurePower gives the build range for this injector as model year 2005.5 to 2007
• Other 9.3L injectors: AP66995 for the 2006 HT570, AP66978 for the 2004 to 2005 DT570, AP66921 for the 2007 to 2010 MaxxForce 9 and 10
• Six injectors per engine

The high-pressure oil rail has to come off to change a G2.9 injector. The injector inlet seals sit on the oil rail and must be replaced before the rail goes back on. Alliant Power kit AP0025 has those seals and backup rings, and it is not in the box with the injector. These injectors are fired by engine oil, so fresh oil and a new oil filter are good practice.

Frequently Asked Questions

Will the AP66992 fit a 2006 HT570?

Catalogs list the 2006 HT570, 295 to 340 hp, on a different injector, AP66995. AP66992 is listed for the 2006 DT570 at 285 to 330 hp. If you are not sure which engine you have, call 530-668-0818 with the engine serial number.

What numbers does the AP66992 replace?

Navistar 1848492C91, 1848492C92 and 5010984R91, and PurePower 6927-PP. Catalogs also interchange it with Alliant Power AP66892.

Is the AP66992 new or remanufactured, and is there a core?

It is remanufactured, not new. PurePower Technologies does the work for Alliant Power, with new connectors, spool valve, coil and harness assemblies. A refundable core charge applies, and it is refunded in full when we receive your rebuildable core.

How is the AP66992 different from the AP66978?

Both are DT570 injectors. AP66978 is listed for the 2004 and 2005 engines and AP66992 is the BANG injector for the 2006 engine, which PurePower dates from model year 2005.5. They carry different Navistar numbers, 1842578 and 1848492, so order by the engine build date.
