It sounds exactly like the set screw in the small pulley.

I can't tighten it though.

Do those things ever get frozen?

If so, what would I do?

Attack it daily with a Q-tip and WD-40 until it turns?

It sews nice.

I'm piecing a quilt on it and have done some mending with it and used it to replace a zipper. It's working well but this noise is driving me crazy!

When I first picked it up a couple of months ago it was whisper quiet. It was going to be my stealth machine to sew at night without waking people up.

It has a belt adjuster that's a little floppy but the sound is dead on like a loose setscrew.

Any ideas?

Thank you.

Is the screw stuck? Can you loosen it? If you can loosen it, I would take the pulley off and visually inspect the inside of the pulley and the shaft to make sure everything is ok.
Does the pulley turn on the shaft or is it tight? If it's tight, that may not be the source of your noise.

Thank you for your response.

I'll have to check those things tonight.

I can't loosen or tighten it. Still sews okay I just hate the noise.

I have errands or I'd goof around with it now...

Some motor pulleys are designed for the set screw to go into a hole in the motor shaft. Maybe yours missed the hole and is tightened down on the shaft?

Rodney and CD...

How would I go about removing the pulley after I take the set screw out?

Do I put penetrating oil on it and let it sit a while?

How do I go about getting the pulley off?

I was able to loosen the screw and tighten it up again but I'm wondering if there is in fact a hole in the shaft that it has missed.

If there was a hole that it screws into wouldn't the screw be more recessed when screwed in?

It's just about flush right now and still making the noise.

It sounds exactly like the other machine I had before I tightened the screw.

Thank you.

Well I got the pulley loose with some penetrating oil.

When I sprayed it on there I covered the vents in the motor housing with a rag and the thing slid right off.

I turned the shaft and I still hear the noise.

I was really hoping it was just the set screw.

Maybe there's a tiny little rough spot or carbon buildup on that spinning doohicky or a brush.

It's not loud or anything it just wasn't there before so it's bugging me.

It still works so I guess I can live with it.

DresiArnaz

I don't hear the noise if I turn the pulley in the opposite direction. Hmmm.

If I had that machine I'd remove the brushes if they are removeable and check them.

Clean the commutator, brushes, springs, and contacts at the same time.

Then I'd oil the shaft bearings.

If that didn't cure the noise I'd pull it apart and check it for damage.

Thanks Joe.
