The noise may be the belt. If the belt is in good condition, spraying
it with some belt dressing sold in autosupply places for auto fan belts
might get rid of the noise. If the belt is old and very hard and shiney,
it may be time to replace it.

Barbara -
If the noise cycles at the same speed as the wheelhead, then it is in the
bearings beneath the wheelhead, and you will have to replace the wheelhead
assembly, which costs about $130. When they are going bad, they can make a
clicking, creaking, and/or scraping sound.

This is one of the few weaknesses of Brent wheels. It is a shame they
didn't just install a grease fitting between the two bearings on the wheel
shaft. Then the bearings would last for a century.

I have an older Brent CXC wheel and I have been experiencing some
problems with the wheel, actually I think it is the motor. When I throw
and apply pressure like when I am centering I am able to slow the wheel
significantly down. Also it makes a noise which I thought was a bearing
noise but my husband who I would trust in this matter says he believed
its electrical. Sounds raspy to me. Has anyone experienced this before
or have any recommendations?



Thanks,

Maybe the motor needs new brushes?

Barbara -
It is impossible to say without hearing the sound myself. If it is
pretty
minor, just ignore it. If it is loud, then you can define it better. I
do
not know what you mean when you say that it cycles at the same rate as
the
fluorescent fixtures. The motor bearings go out only very rarely on
electric wheels. However, the motor brushes do wear out, and when they
are
about to fail, they will make more noise. If there is any chance that
the
motor brushes are wearing out you need to get them checked out right
away,
because if you keep running the wheel you could seriously damage the
commutator (contact field) on the motor armature, and that would mean a
new
motor - expensive.

Try to describe the quality and cycling of the noise much more
accurately,
and I might be able to zone in on the specific problem.

The bearings were my first thought. The strange thing is if you get it
up to speed and turn it off and let it coast down it stops making the
noise. If it was the bearings I would assume it would not do that.

fixtures. Doesn't sound scraping like a bearing.

Do you still think it's the bearings?

bearings on the wheel shaft. Then the bearings would last for a century.>

Vince is right here, IF you grease the bearings with a grease gun on a
regular basis!
For most irritating noise, give the bearings, if you have any, a simple
grease gun treatment. Works wonders.

Very likely you have a problem with wear associated with the motor. The
armature and/or the brushes may be worn and need replacement. Possibly a
new motor. Hope this helps.
