VCCA Home Forums TECHNICAL - GENERAL Electrical - 6 volt 943-B & 943-J generator questions.....

What are the differences in the two generators besides what year cars they came on? What parts are/are not interchangeable between the two? TIA, Bob

Not counting the generator pulley, the only difference between the two generators is the position of the cut-out on top of the generator and the Delco-Remy tag with the model number. Other than that all of the parts are interchangeable since both generators are the same.

Thank ya' dog....you da' man...I mean dog...woof, woof

Bow Wow!!!

Hey JYD another generator question:

Will a 937-G generator parts interchange with a 943-J? The reason I'm asking all these generator questions. Is that I have new field coils, bearings, brushes & a NOS armature for
a 943-J. There is a 937-G on "Greed"-Bay for a decent price
(for now!)that I might bid on. If I got it I'd rebuild it for a spare for my '29 coach. What say ye', oh' great dog of the Pacific North West?

You could probably make a 943-J from a 937-G, since many of the parts are the same. I think that the third brushes are different between the two as I remember. However, I would still go with the 943-B and the 943-J instead. The 943-B is an easy conversion to a 943-J by changing the location of the threaded holes for the cut-out and changing the Delco tag.

Thanks JYD, I'll wait until I find another 943-J or a 943-B.

Yep, you are better off looking for another 943-J generator since they are not that hard to find. The rare part is finding the correct pulley for the year application.
