Information:
3500 Family Of EnginesReference: Engine News, June 1987, Page 4, "Fuel Injector Trim Bolt," on all 3500 and 3600 Families of Engines. Engine News, December 1988, Page 1, "One Piece Tappet Used In 11 mm Fuel Injectors," in the 3500 Family Of Engines. Engine News, September 1989, "New Fuel Injectors Available For Parts Service," in the 3500 Family Of Engines.This article replaces the January 1987 Engine News article "Fuel Injector Reference For 3500 Family Of Engines."
The 3500 Family of Engines has a number of different fuel injector assemblies for different operating speeds, power ratings, and product improvements. This has caused some confusion. This article will summarize:
... all of the injectors that have been used.... the differences between the injectors.... how to identify different injectors.... which injectors are used for various applications, operating rpm, and power ratings.All injectors for 3500 Family of Engines are one of two types. For purposes of this article we will refer to then as Type 1 and Type 2. Type 1 injectors have 10.7 mm (.42") diameter plungers. Type 2 injectors have 11.0 mm (.43") diameter plungers.
Illustration 1. Type 1 injector.There are other basic design differences between the two types. Refer to Illustration 1 and 2 for examples of Type 1 injectors, and Illustration 3 for an example of a Type 2 injector. When not installed, injectors may be identified by the injector case. Type 1 injectors use a one piece case that encloses the plunger and barrel assembly as well as the nozzle assembly. Type 2 injectors use a case that encloses only the plunger and barrel assembly and a separate cone that encloses the nozzle capsule. When installed in the cylinder head, Type 2 injectors can be identified by the trim bolt as shown in Illustration 4. This trim bolt must not be adjusted (see Engine News, June 1987, Page 4, "Fuel Injector Trim Bolt"). Newer Type 2 injectors may also be identified by the part number etched on the tappet. Type 1 injectors have no trim bolt. Older Type 2 injectors may also be identified by a two piece tappet as shown in Illustration 5 (see Engine News, December 1988, Page 1, "One Piece Tappet Used In 11 mm Fuel Injectors").
Illustration 2. Type 1 injector has identification information which shows orifice diameter in mm, number of orifices, and spray angle.
Illustration 3. Type 2 injector.
Illustration 4. Location of trim bolt on Type 2 injectors.
