The jist of what he said was to first check the tension on the belt. If that
seems okay, hold a block of paraffin against the belt for a few seconds as
it runs. It, theoretically, should be chirp free for an extended period of
time.
I’m glad you brought this up again, as my Brent C had developed The Chirp,
and I am going to try this trick tomorrow.

I don't think my wheel's problem can actually be classified as a chirp.
What it does is really not audible at all. I'll try to describe it...
I have a Brent C. It's about 5 years old. Running at full speed, I can
detect nothing at all amiss. However, as I slow down the wheel head, I
can *feel* a motion in the machine that I can only describe as a
'heartbeat'. By this I mean I can sense the movement with the inside of
my knees as I brace them against the wheel. It reminds me of my washing
machine just before it shuts itself off because the load is not evenly
distributed. It is more noticable the slower I go. It seems to be coming
from the motor, but does not seem to translate into any detectable
motion in the wheel head.
Is this something I need to be worried about. If it is, is it something
I can correct myself or should I hire a professional. I have a somewhat
decent mechanical sense and feel that, with the proper directions, I
would like to tackle the job...but, then again, maybe all wheels have
'heartbeats' and I just never noticed!

This can cause a problem if you make really wide things
because a little quiver in near the center of the wheel head
isn't much but out on the rim of a wide thing it can
translate into something significant. I have also had this
movement problem on very tall things.
I am not an electrician, but if it is not the bearings then
I would suspect the motor bushings. DC motors tend to wear
these out from time to time. If that is the case, on most
Brents it is a relatively simple fix and you should be able
to do it yourself.
Call Brent and talk to someone in the service department.
Have your model and serial number handy, that should give
them some idea on the motor.

I think lubricating wheel belts applies only to newer
Pacifica wheels. Instructions that come with the wheel
tell you to lubricate the belt.
Older Pacificas and Brents are different. They use
automotive type belts. I would not use a lubricant
on these belts.
Has anyone used paraffin on these belts with
good results?

I also have a Brent C. I've had it for way over 5 years and recently have
picked up on just the thing you explained. It doesn't seem to affect the
motion of the wheel but does have a thump or "heartbeat". Yesterday I went
out in the studio and sat down to throw and ........nothing, dead, stepped
on the pedal, jiggled the wheel and it started but was really loud. I
thought it was the brushes but they seem to be okay. I think it may of
gathered moisture and was just cutting out. After the heat was on and it
wasn't so damp it quit. I haven't ever had one minute of trouble with that
wheel. I have always taken it for granted that it would just hum along
smoothly, I've sort of decided it's the conditions in the studio and not
the wheel mechanics that are causing the trouble. I would recommend it
highly. If you do find out an answer to this mystery let me know, I'd be
interested in what the true cause is myself.

When I got my pacifica wheel, it came with a silicone spray lubricant. When
the birds start singing, I just spray the belts while the wheel is turning
at a medium speed.

I don't currently have a Brent, however, I used one for a number of
years while I was in school (more time than I'm willing to admit on this
thread.)
If memory serves me correctly, the wheel that was my favorite was an old
CXC model that had a belt drive from the moter drive shaft to a large drive
disk affixed to a shaft to which the throwing head was attached. The shaft
passed through a "pillow block" type bearing. I suspect that the bearing is
what is giving you your problem, if I understand it correctly.
An occasional chirp is definitely a sign of bearing fatigue or failure.
However, if no such sound exists, then pay attention to whether or not the
speed of the wheel is actually fluctuating or is the "heart beat" that you
are feeling a lateral movement of the clay (as if it were suddenly falling a
little off center.) If this is the problem it should become more pronounced
as you throw taller, wider objects. Try slapping a 25# block of mud on the
wheelhead, pull up a nice big bowl and see what happens. If there is a lot
of movement rather than speed fluctuation replace the bearing (compared to
other potential culprits they are inexpensive.) Hope this helps........

Hi,
My Dad swears by Fels Naptha (sp?) bar soap rubbed on
automobile fan belts to get rid of noise. Possibly
this could be a cure for a wheel with an automotive
type belt?
Cheers,
Jeanne W.
In Idaho where I find frozen buckets of glaze even
more annoying than frozen clay.
