I have 8 new in orig. boxes. Boxes say "injector assembly, cummins, BM491, 2941-PH-51-11-C, packed 10/50." I wish to sell them but I do not know what engines they fit or what they are worth. Anybody have any ideas?

I think you are missing a couple of numbers.

BM part numbers are typically 5 digits long...

so I think it should be either....BM491_ _ or BM_ _ 491....neither of which I can find in my Injector lists so I'm not much help.

I found a stock No. on the boxes that reads "3H4585A/148". Does this help? Thanks much for your help by the way. Floyd

Sorry Floyd,

those new numbers don't mean anything.......it's the BM number that is the key.

you might need to look a little deeper....maybe any numbers on an actual injector?

The upper (aluminum) section of the two piece casting # is "H-9332" and the crudely cast steel lower part # is 4807-5. These injectors were found with various CAT parts (all new in boxes) that indicate dates of 1930s and 1940s. I have talked to Cummins main office (who could not find them) who referred me to local dealers who could not find them as the numbers are to old. They referred me back to main Cummins office. Dead end.

I just talked to a very knowledgeable man (Warren @ "PREMCOdieselparts.com") about my injectors. He knew what I have but his paperwork does not go back that far. He was sure these were for older/smaller cummins engines, probably 190 or smaller. He referred to them as "early style single disk flange type" injectors. He said for many years his business (re-building injectors) had not had any quarries for these but in the last few years he has gotten a few quarries from customers in process of restoring old trucks. Anybody out there have any more info than this?
