Service Magazine, SEPD1516, 25 October 2012, "New Injectors Are Used In Certain C7 and C9 Machine Engines ". Disregard this article. Refer to the article that follows. Effectivity has changed as well as new part numbers added.

Reference Service Magazine, "A New Unit Injector Hydraulic Pump Group Is Available for Certain C9 Machine Engines" for information on the related project.

Description of Change: New injectors are used in certain C7 and C9 machine engines. The new injectors utilize increased hardening and wear coating to critical injector parts in order to minimize damage from oil-side debris. These improvements will improve symptoms such as misfire, rough running, as well as fuel dilution of the engine oil.

Adaptable To: Refer to Table 1 for the correct injector part numbers.

Table 1

Old Part Number	New Part Number	Part Description
328-2573	387-9434	Fuel Injector Gp
328-2574	387-9433	Fuel Injector Gp
328-2576	387-9432	Fuel Injector Gp
328-2585	387-9427	Fuel Injector Gp
328-2586	387-9426	Fuel Injector Gp

The change is effective at the factory with the engine serial numbers that are listed in Table 2.
