It also depends if the Cummins shop knows what you are talking about. I went to the local Cummins shop up here in NH and he looked at me like I had three heads when I said "Maintenance Free Crankcase Insert". I didn't get a chance to write down the part number before I went so we had to look up the Bulletin. He still thought I needed the "regular" filter for the maintenance free one to work. He also said nothing is ever maintenance free.
He also said "It's probably better if you come here with part numbers." And I thought "Why? So, I can do your job for you?" But since I was in a fairly decent mood, because I was half-way through my coffee, I just said "Will do!"
The Maintenance Free insert will fit CM871, CM2250, and CM2350. Not sure about the CM870 as it doesn't say anything in the Bulletin regarding that model engine. I also know nothing about the CM870. So, I do not know if it even has a crankcase filter.
Part number for the Maintenance Free insert is 3691476. You can still get the regular filter as well for those who do not wish to use the maintenance free insert. If you want the regular filter, the updated part number is 3691687.
Lol where is the Cummins dealer in NH? If you don't mind ? Might be closer to me than Dedham Ma
