This is the Alliant Power AP66989, a remanufactured G2.9 BANG fuel injector for the International DT466 7.6L. Catalogs list it for the 2006 model year engine at every rating from 210 to 285 hp. PurePower Technologies, which remanufactures it for Alliant Power, calls it the 4HB injector, 6926-PP, and gives the build range as model year 2005.5 to 2007. It replaces Navistar 1848489C91, 1848489C92, 1848489C93 and 5010983R91.

BANG is the name catalogs use for the later G2.9 injector, the one that took over from the 2004 to 2005 injectors partway through 2005. On the DT466 one BANG injector covers every rating, so there is no low and high horsepower split to work out. What matters is the engine build date. The 2004 to 2005 engines take AP66976 or AP66977, and the 2007 to 2010 MaxxForce DT, engine serial 3,000,001 to 3,300,000, takes AP66918. Alliant Power lists new connectors, spool valve, coil and harness assemblies on this injector, and it comes with its chamber gasket fitted and two injector seal rings. The engine takes six.

Specifications

Fits / Applications

• International DT466 7.6L, 2006 model year, all ratings from 210 to 285 hp
• PurePower gives the build range for this injector as model year 2005.5 to 2007
• Other DT466 injectors: AP66976 and AP66977 for the 2004 to 2005 engines, AP66918 for the 2007 to 2010 MaxxForce DT, engine serial 3,000,001 to 3,300,000
• 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. Use the chamber gasket and seal rings supplied 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 AP66989 fit my 2005 DT466?

Only if the engine was built after the change to the BANG injector. Catalogs list AP66989 for the 2006 model year engine and PurePower dates it from model year 2005.5; earlier 2005 engines are listed on AP66977. Call 530-668-0818 with the engine build date and serial number.

What numbers does the AP66989 replace?

Navistar 1848489C91, 1848489C92, 1848489C93 and 5010983R91, and PurePower 6926-PP. Catalogs also interchange it with Alliant Power AP66889.

Is the AP66989 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.

Does the horsepower rating matter when I order the AP66989?

Not within the 2006 DT466. Catalogs list AP66989 for every rating from 210 to 285 hp, and PurePower lists it for all horsepower levels of that engine. The build date is what separates it from the 2004 to 2005 injectors.
