Section 2.5
EGR Fuel Injector Nozzle
The removal and installation procedures remain the same for the non-EGR and EGR fuel injector nozzle. There are minor differences in the injector nozzles for the two engines. The EPA 98 engine uses injector nozzle #1070 until engine series number 744382 and from engine series number 744383 on, the 98 engine uses injector nozzle #1281. The EPA 04 EGR engine now has two injector nozzles – one for low HP and the other for high HP. Each injector nozzle is stamped with a production number for the EPA 98 and EPA 04 engines. See Figure "Injector Nozzle Identification" .
