Maybe when the thread jam happened the safety clutch disengaged. Its purpose is to disengage when there is stress on the hook so as to prevent damage to the machine. To see if this is what happened, go into the link for adjusters that amuckart provided and scroll down until you see info about the safety clutch. It will be a fairly easy diagnosis and if that is what is going on with your machine the safety clutch should be easy for you to engage again.

What size needle and thread are you using?

I think machinehead has it right and the safety clutch has disengaged. The very last page of that PDF I linked to above has instructions on resetting it.

That machine needs a bloody good clean out before you go too much further. Remove whatever bits come out easily then get in there with a good cleaning brush or even a tooth brush.

Ok everyone..........

Amuckart had it right --- the safety clutch disengaged (and the machine is apparently also missing a spring on the safety clutch).. Anyway, I had a guy come out yesterday..... Problem resolved & machine is sewing!

Thank you all for the help --- but this was too big of an initial problem for me to conquer, only just learning the art. That said ---- because of this problem, I DID take much of the machine apart, myself, and am starting to learn how this thing works.

Again, thanks all.

ALSO --- the Technician said that my "Servo Motor with Gear Reducer" is awfully loud for being a Servo Motor... It's a brand new motor from Toledo Industrial...... Would anyone agree with this?? You can CLEARLY hear the noise on the video I posted. The Technician said it sounds like metal grinding against metal.... Any thoughts on THIS issue would be greatly appreciated. Thanks!

The Chinese have started producing brushless motors, they tend to whine a lot, almost a new pump (that's all I can think of) kind of sound. I don't know if it gets any better with wear either.

The problem is this particular motor is the metal gears in the reducer part of the motor,they have a gear whine that usually quiets down as you use it more.

Well my latest shipment of Chinese Servo 550 watt Motors make no real noise at all. In fact they are as close to perfect as I could wish. Running from 300 revolutions to 3.600 max. They can be set at any max Speed in between and operate from 300 to the set speed. They run so quietly and efficiently I can't understand why anyone would use anything else. Especially when they have excellent torque at all revolutions.

Sewing 7/8" of Harness at 300 revs is a snack.

Kindest Regards.

Jim,

The reason that anyone would want to use anything different is this motor(w/builtin gear reducer)is it goes down to almost 10 rpm(output speed) & still has torque,top speed is 800,we also have the same motor as you have but since it only goes to 300 rpm this is still to fast for most leather machines,unless they put a speed reducer on it which cost more $$ & is not easy to install for most people.

Cheers,

Bob

Sorry Bob actually I was referring to Clutch Motors, my mistake. I put 1 1/2" Pulleys on all my Motors so this reduces speeds considerably, especially when a reducer is used.

Please have a Happy day.

Kindest Regards.

Jim.
