Cassette mechanism high pitched noise

[steedums]

I have a high pitched loud noise that comes and goes randomly. Any ideas?

it sounds like my GF9090 it doesn't do it other than on new tapes!!! old ones don't seem to do it then only randomly hasn't done now for weeks!! I always put it down to modern tapes

If the noise is coming throught the speakers, try this post:

The noise isn't coming from the speakers. It's coming from the mechanism. It can make the noise during fast forward and rewind too. I can't nail down where it's coming from. Is there anything that could need lubrication?

If it is not heard through the speakers, then it seems it is definitely a hardware issue. Maybe put a light coating of lithium grease on the around the hole where the flywheel shaft goes in. That's a usually a metal on metal spot.

I'll give that a try. I have white lithium grease. Is that the same stuff?

Yup, what fatdog said

You might also try a small shot of WD-40 down the shaft of the motor if the lithium grease trick doesn`t work

the motor can also make the noise ,, i had a box that would do that it would come and go then one fine dandy day the motor took a dipp

I opened it up and stopping the flywheel or any of the other moving parts seems to make no difference. I'm guessing a bad motor is making the noise. Looking up what's printed (MMI-6A5HO) on the back yielded no results. Are these motors very brand specific? it's DC15V. Maybe there's a way to lubricate the motor.

What boombox is it? You never mentioned.

sorry, it's a panasonic rx-5050. I wrote that on the youtube site, but never here.

I've had a couple of boomers that did the same thing. :annoyed:
In both instances it was because the pinch roller was not putting enough pressure on the capstan and the tape.
I rebent the pressure spring under the pinch roller and it worked.
It took a few times,but eventually it worked,just be patient.
Just my 2 cents...... Good luck with it.

I took it apart and cleaned everything I could get to, but it still made noise. I tried applying more pressure to the pinch roller, but that made no difference either. I applied a couple drops of sewing machine oil to the motor output bearing, and I haven't heard anymore noise *fingers crossed*.
