Cummins is one of those organization that sells their service and parts manuals and doesn't post them on the web. I would love to find the electronic version of the manual for my ISB 6.7L Cummins engine.
If you go to Cummins web site they should allow you to register and then pay for the service manual. If I remember correctly, their manuals are not cheap.
