I'm looking for specs for an obsolete 47 frame motor, specifically,
I'm
trying to find the shaft size.

Any help is appreciated, Roy

The info I found only had 2 fractional HP motors - 48 and 52 frame
size.
Frame 48 is 1/2" shaft with 3/64" key.

A 47 frame should be 47/16 " from base to shaft center-line - a rather
odd
number.

Doubt that helps any.

I appreciate the effort.
I bought an old, thirties or forties, floor model drill press. The thing
has
no brand name or model on it, so I have little to work with. I'm
stripping
it down to more or less rebuild it. It currently has a big ass dog of a
motor on it, that's clearly wrong and too large for the motor mount. I
think
someone used this motor because it's a 66 frame, which uses a 3/4" shaft,
the size of the bore of the 4 belt pulley it uses. These days there's
nothing on the market in a fractional HP motor, with a 3/4" shaft, except
a
66. So I'm scrounging on Ebay and I see this guy has a 1933 1/4 HP GE
motor,
with a 4 belt pulley on it, and has no clue what it came off of. The
thing
is the exact same color of my drill press, so I'm starting to think that
this might just be the missing link, but I can't get a return email from
the
seller, and I can't find any information on a 47 frame motor. Ultimately,
the guy did get back to me, and the pulley is smaller than mine, and the
non
reversible rotation is wrong, so it's useless to me. I will probably just
get a 56 frame and a single belt pulley, and be done with it.

If you can find a suitable smaller motor, you can always sleeve the
shaft up to fit the 3/4" bore pulley.

I thought about that as well. That's probably the most sensible thing to do,
that is of course after I locate the obsolete quill pulley bearing that
broke on disassembly. So, if you've got , in your bag of tricks, a source
for an obsolete or equivalent ( Fafnir 202PP3 ), do let me know. Thanks
