40C Idler wheel shaft thread size?
40C Idler wheel shaft thread size?
Title says it pretty much. Need to chase out the idler wheel shaft threads, need to know the original size. Amazing what 60 years of siting does to threads!
40C, 420C, 1010C-L-BH, Cat D4
Should be 3/4" NF.

Sorry, I assumed 4 or 5 roller. I don't know what thread that is, it is tapered like NPT, so I am not sure it is any sort of standard thread.

You could try 1" or 1 1/8" NPT, but that is purely a guess, be careful.

The threads should have a taper to them.

3/4" NPT shows to have a 1.050 OD. and 14 TPI. At least that is what google tells me. If he runs a 1 1/8-12 tap thru it there will sure be no taper left then.
