Series 60 Injector Height Adjustment

The injector height is adjusted using the injector height gage, J 39697 (DDEC III/IV) or J 35637-A (DDEC II and I). On engines equipped with a Jake Brake ® , move the handle on the injector height gage to the alternate position, 90 degrees to the shank. A height gage pilot hole is provided in the fuel injector body on the machined surface contacted by the injector clamp near the solenoid.

Note: Be sure the height gage seats on the machined surface with the tip in the pilot hole. Foreign material in the pilot hole or on the machined surface may prevent accurate setting of the injector height.
