For $12.00, I bought a 5 HP, SINGLE PHASE Baldor compressor motor that
has a problem. When I spin it up by hand, it turns, but a little
roughly and then spins by itself, but not for very long. It stops too
soon. It is not, by any means, seized, but there is too much friction
compared to what it should be. I did not run it under power yet

It is ball bearing based, which I concluded after seeing grease
fittings on it.

My hope is that it should be an easy fix. Either the grease caked, or
perhaps the bearings need replacement. Any thoughts on how to proceed?


Baldor usually lists the bearing # on the motor dataplate.....

Suggest should install sealed bearings instead, theses will have the
same ##
but with additional "ZZ" suffix....

makes perfect sense...

Upon reassembly, be sure and plug the old grease holes.

you mean, just put little bolts in the grease holes if I install sealed
bearings?


Yup.

Personally, I would just use a small plastic dowell instead...tap it down
into the hole--avoids confusion at some later date should someone think
about perhaps greasing them...and also then easy enough to drill back out
should you ever decide go back to using the gallerys as lube ports...
