What does black smoke mean on a Cummins Engine?
Black smoke means you need to check for: Faulty fuel injectors: If your engine has faulty injectors, they can cause a return flow or drop in fuel pressure, which alters the amount of fuel reaching the engine. Faulty injector pump: Pumps affect the fuel pressure and injectors directly, and a faulty pump can do a lot of expensive damage.

What’s the OBC method for STC injectors?
There has been much confusion about setting STC injectors, particularly those CPL’s that have reverted to setting injectors using the OBC (Outer Base Circle) method. The information contained here applies only to those engines with STC injectors that are set using the OBC method.
How many injectors do you need for a 50 pin connection?
For a 50 pin connection all it takes is one pin to loosen from the heat to destroy the ECM. It is recommended that drivers carry 1-2 extra injectors in the truck in case one goes out. Usually they go out in pairs which makes sense to carry 2 at all times.
How do you adjust the injector rocker torque?
Refer to the engine model and CPL for the correct injector rocker lever adjusting screw torque value. Use a dial type torque wrench to tighten the injector lever adjusting screws to the specified torque. If the screw causes chattering during setting, repair the screw and lever as required.
