OK. The engine serial number stamped on the back of the block 60101190 is a good number for a 4bt. However, that serial number did not come with the P7100 pump that is on there. That engine was a CPL 0858 which had a VE pump and was rebuilt in the Cummins DRM factory in 1996. DRM is Diesel Recon de Mexico. Somewhere along the line that rebuilt engine got joined to the P pump. Who knows when that might have happened. That injection pump is a correct P7100 that would have come on a CPL 1839. It has the correct power steering pump for that one as well. Can't see the turbo side. This isn't such a rare thing. Companies who had fleets of trucks with these engines often repaired one engine with parts they had available. They used a rebuilt short block assembly from one engine and transferred the parts from a P pump engine to it. You would never know this if it weren't for that Recon serial number on the back. Most P pump engines have the STORM block. I suspect this one is an early style block. If you look on the turbo side and it has 2 large freeze plugs then it is an early block. If you want to go into Cummins Quick Serve I can give you a serial number for a CPL 1839. That will show you the original part numbers and any updated numbers. With those numbers you can search online and find OEM parts or aftermarket replacements. I cannot tell you what parts may have been changed in the recon process.
