Thank you. What is NGK?

A brand of bearing. Japanese origin; good quality.
Thank you. So, your vote is to just replace the bearings, not
to try
to just re-grease them?

If they grumble, they're shot. Replace them.

Got it. Thank you Lloyd. Yes, they do grumble, like they have
sand in them.

a heads up..DONT buy India made bearings. Only US, Japanese,
European,
and marginally..Chinese bearings.

Forget the Chinese bearings.

A good while back we rebuilt the spare spindle for a IR T-25 air
compressor (being used as a natural gas compressor by the local
gas
company). He keeps a spare because of all the problems that
compressor
gives him. Anyway it was put in service about 2 years ago with the
bearings that he had gotten from the local NAPA. Well less than a
year
later we had to take the compressor back apart because it was
making
noise. Inspection found the balls in the bearings looking kind of
like
a baseball with half of them being shiny and the other half being
pitted. Lousy steel in those balls. They where replaced with some
good
USA bearings which will hopefully hold up much longer.

Thanks.

Eventually, I will sell this motor, either alone or as part of some
repowered package, but I would feel better if I spent 10 extra bucks
to get better bearings. The greatest cost of this item will be my
time
anyway.

The spec for bearings from Baldor is: DE bearing 6307, ODE bearing
6206. Not sure what DE and ODE means. I have no idea where I can
find
such bearings, will try to call Baldor.

i


DE=drive end, ODE=opposite drive end, if my memory serves me
correctly. For DC motors, it's CE (commutator end) and OCE (opposite
commutator end)

Those are very common bearings...



great, I see 6307 on ebay for next to nothing... the dealer wanted $25
for it...

There is nothing wrong with cleaning and inspecting the bearing you are
condeming. I have cleaned and inspected hundreds of ball bearings. Most
were reuseable. I always guarenteed my products better than any new
alternator is guarenteed, so this wasnt a 'fly by night' operation.
You can actually learn alot by cleaning the bearing and looking closely at
the races and the balls.
