I have a few questions,there are alot of 3.9 that I have looked at that have there Id tags gone from the front cover??


1.Some of the rebuild parts ask what CPL # you have,if gone what do you do?
2.I do know that some info can be taken off the id # from the pump.
3. Is there any numbers on the block to check the numbers with Cummins to get a replacment tag?
4. Do you even worry about this and go on?

anybody have any thoughts about this???

The engine serial number is located on the rear of the block just below the cyl head. If you see one that has XXXXXX over the numbers and has a new number below it it means you have a remanufacturerd engine. My local Cummins parts supplier no longer wants the CPL number but now wants the serial number. I am somewhat hesitant about buying an engine without the tag. It could be a trade in core that someone transferred the tag to the replacement engine or in a worst case senerio it could be a stolen engine from an industrial engine piece of equipment such as an irrigation pump or a remote generator. In some cases the tag may have vibrated off but that isnt really a common occurence. Amazing how a freshly painted core engine resembles a nice newly reman engine.
