    Didnt know if there was a site online to find a parts diagram for a Cummins Big Cam IV? Need to look at the power steering assembly, and see whats involved. I could probably go to Cummins in Wichita, Ks, but my computer is much closer!(lol)
    thanks,

    Can anybody tell me the major differences from a Big Cam III and a Big Cam IV? I see several "cds" on ebay, but they cover Big Cam I-III. If one of them would work, at least I could print out some diagrams to take to the shop for me.

    My best guess is the power steering pump would be the same.Not sure of the differences between I-IV ,you will get alot of useful info from the cd`s.

    The main difference is the BC IV has the low flow cooling system. I can't remember for sure but I think the block is also machined for upper and lower press fit liners as well. Many of the parts will interchange with the exception of cooling system parts.
