I posted a picture of the squirrelcage motor in my homemade "air
filtration system" with 18x24" filters. The motor has started to
make a high pitched squeeking noise, and the center circular pieces
in the picture (bearings?) are getting hot. Is there any way to
lubricate, or salvage the motor, or do I need to get a new (used?)
motor? This thing has had many, many hours on it, since I use it
too to circulate the air in the basement. So I owe it gratitude,
but can afford another motor. OTOH, if it can be saved somehow,
that would be good. But I don't want it to catch fire!!!

Any advice is appreciated!

Most likely the bearings Han. They are most likely replaceable for
small dollars. Pull the motor, remove the bearings and let your
fingers do the walking to find a local supplier. Take one down with
you to get the right replacement. You can try to lube them with a
little oil, but chances are that won't be a very long lived fix.

Thanks, Mike!!

No problem Han. This is a very common fix. Having looked at your picture
over on the binaries group, it will be an easy job. Just remove the nuts
from the end cap screws (they are long screws that go the length of the
motor), and carefully pull it apart. The bearings should knock out with a
dowel or the likes, from the inside. Likewise, insert the new ones from the
outside, just being careful to seat them as squarely as you can before
beating them in. It'll all be good for probably under $20 - even in NJ!
