An Improved Lifter Is Used for 3500 Engines with Mechanical Unit Injectors {1102, 1121, 1123}
- Engine: Commercial with Mechanical Unit Injection (MUI)
- 3500
Description of Change: An improved lifter for the valves and the injector is now used. The new lifter has an improved follower. The follower has a semi-crowned profile that reduces edge loading on the camshaft.
Adaptable To: The new 346-7515 Lifter As is adaptable to all 3500 Engines with mechanical unit injectors. Table 1 lists the former parts and the new part.
