MBE 4000 EGR FUEL INJECTOR NOZZLE

The removal and installation procedures remain the same for the non-EGRand EGRfuel injector nozzle. There are minor differences in the injector nozzles for the two engines. The EPA98 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 EPA04 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 EPA98 and EPA04 engines. See Figure 44238 . ‪

NOTICE:

EPA98 injector nozzles may not be used in an EPA04 EGRengine. Verify correct nozzle before insertion into engine. ‪
