    Default Cummins Factory Parts Manual M939 Series ENGINE ONLY

    I omitted the fuel pump and injector break down pages because I don't want anyone thinking they can buy the listed part and make a good working pump or injector. Leave that up to a professional. Some of the part numbers are old, this manual was printed in 1982. The number listed should get you a start that can be superceded to the latest p/n from Cummins, then NAPA, CR, etc.


    I have one for the 809 series too, just need to scan it.
