Jet JWL-1642EVS-2 motor - jim schlemmer - 02-26-2019
Hi all.
I see that just recently somebody posted about his Powermatic PM 3520 lathe motor and this motor seems to be very similar to my Jet lathe's. But whereas that fellow's issues are electrical, mine are mechanical. The front (pulley end) bearing seems to be on its way out. There's noise and too much play in the shaft. Jet doesn't seem to break the motor down on a parts basis -- only $500-ish for a new one.
I'll probably end up yanking the thing out and having a look but thought I'd check here first in case anybody had some advice they'd like to dispense. I'm fortunate to have a business named "Bearing Distributors" about 1/2 mile from my home, so they might be of some help.
Thanks,
-Jim

Look for a motor rebuild shop. Take it them...

Hope these videos help some.
This short video shows how headstock disassembly.

I agree with woodtoolgy take it to a rewind shop you'll get new bearings when they reassemble it.

Remove the old bearings and take them to the bearing shop to buy replacements. If you'd rather not do it yourself, then take the motor (or even the whole headstock) to a motor-repair shop and have them replace the bearings.

If you take it to a motor shop, get a price before they do the work. Bearings are cheap. Labor is not.
If you do it yourself, put a scratch across the end bell to frame joint or joints (if doing both ends), so you can align them correctly on reassembly. It’s probably just 4 rods with nuts and the ends pop off, and if three-phase, there’s nothing in there that moves but a rotor. Easy peasy.

As someone much less experienced with such things than TDKPE, I'd like to speak up to agree. It really is not difficult to change bearings in a motor, even for me. Here's a link to pictures showing bearing changes in a different motor. The major difference in a 3-phase motor is that it's easier to work with because it lacks the parts that can get in the way.
