I was reading a thread here a while back where someone had said that the CTD in the Dodge trucks were a Medium Duty engine in a Light Duty truck.

What exactly does that mean?? Is the CTD like a heavy equipment or semi tractor engine ??

Thanks,

 

The B series engine is the smallest in the Cummins "mid-range family" The mid range includes B, C, L-10, m-11, N-14, ISL, ISM ISX,

 

Basically, the engine is built tough.

It is used in some medium duty (heavier) trucks.

 

it means you've got a 1,000,000 mile motor in a 150,000 mile truck. :-)

 

Mac, LOL! I have heard bofore that the engines outlast the trucks that is for sure. would love it if the million mile part was true in my case, that is for sure.

 

the one in your truck isnt used for semis because thats more than medium duty. They use these motors in buses, medium duty trucks which are flatbeds or like a 26' box truck. I think 26,000 lbs is the max weight to be considered medium duty
