GM Generator fan nut?

[4d9r]

Put new brushes in my '59 235 generator, lost the nut that holds the fan on. Can't find a vendor.
Anybody know where I might buy one. Junkyards around here are barren.

Thanks,
Terry

Figure out what size and thread it has (maybe someone here can come up with that) and then check the Dorman cabinets at a local parts house.

You might also check the nuts on older alternators as they may have used the same size and thread.

You could get away with using an over the counter nut the right size and thread until you find the correct one but it wouldn't look right.

Yeah, it's like an 11/16 fine thread, right between 5/8 and 3/4. No Dorman help, no older generators to be found. Really surprised nobody in the hobby is repoping them. Still lots of
gennys being run especially by the resto guys. I know they get lost because I took down another generator I had in the rafters to pirate that nut and......nope that one was gone too

From looking on the HAMB it's a 11/16 x 18 nut One of the posters said that Speedway has 11/16x18 jam nuts for rod ends that are thinner like the original generator nut.

The other option might be to check with the local generator/alternator/ starter rebuilders.

Alt. nut is the same size.

Thanks for the replies. Speedway was a help.
Knowing that an alternator nut is the same solves the problem Wrench Bender.
