Cat3406

Are you talking about the cam in the injection pump or the one in the engine.

 

Ok, then what does engine cam have to do with pumping units ??? All it does is open and close valves.

 

B & C are the same motor just caterpillar put in a Mickey Mouse electronic pump piece of junk it was called the Bridge motor!
I’ve had a few I just take the electronic pump off and put the manual pump back on the motor!

 

There’s a difference between a supply pump and a injection pump 855 Cummings had a supply pump cam opened and closed the Injectors , 3406 has an injection pump that runs directly to the nozzles

 

I still don't understand the guys post.

Engine cam has nothing to do with pumping units.

Not clear at all on what he is talking about.

 

If its a reman engine there most definitely will be a S/N stamped somewhere on that block. A full S/N should allow the build sheet to be looked up and see what it left the factory with.

Even a part number or arrangment number off the pump could clarify a lot.

 

PEEC was the electronic pump. I’ve owned mechanical C models and know of many of them.
