Once again, if you are within the warranty period I would contact the place you purchased the motor from and have them check it out. Even if you are not in warranty, why not call them and get their advice? Good Luck.

I just purchased a sew-quite 5000 nps and was having similar problem, extra stitch, and refused to stop at the top. Reliable took it back, I had it returned no charge 3 days and works perfect on any weight material. Maybe you just have a bad unit?

If there is anyone out there that needs a clutch motor I've got a Adlee 1/2 hp.clutch motor in excellent condition complete, 1450 1725 rpm. It's yours for the shipping cost (unless there is a belt guy that wants to make me a simple belt, not my craft). Maybe this is just surplus and worth nothing, I don't know.

So I took an extra turn through the first set of thread guides , revisited the threading diagram ,which sucks by the way, and found it needed to go through an almost indistinguishable guide closer to the needle, and one of the guides is missing completely but i don't think that one is imperative to operation. Also, just because I'm stubborn, I changed to black thread. Success! And I went from two layers of vinyl to two layers of what I would think would be like heavy boot leather, hard and 1/4 total with what I would think was a perfect stitch and had to make no adjustments. Only thing I noticed was a indent from the inside foot. In fact I think the stitch on the leather looks better because with the vinyl I was have trouble getting the top thread to be in the center, it wanted to be at the bottom. Maybe with the vinyl I need to gone done a thread thickness and needle? On the thinner leather it looks fine.

I try any or all these solutions one at a time and see what happens. If I get a change I'll report back.

Off the top.

Hi guys, I just got my shipment of threads from the thread exchange and thought I'd be set up. I'm running a Mitsubishi LU2-4400 walking foot machine and I just put a sew quite 5000 with needle positioner on it (which by the way isn't working) and got myself set up with a 140 leather needle and 138 nylon thread. The problem I'm having is that after running a foot or two, and it's not consistent, the upper thread twists tight until it forms a ball and breaks off at the needle. I have checked the threading over and over, needle is in correct as far as I can tell , groove to left, I was trying this on two layer soft upholstery leather maybe 3/16 total, and two layers vinyl. What should I check next?

I've got the Mitsubishi LU2-4400 up and running with no real issues except it goes like stink, so next step is change to servo motor. Ordered thread from thread exchange as it seems to be a problem getting heavy threads even in Toronto's sewing and fashion district. Any comments on the Tech Sew 550 servo?

Okay, so I bought the Misubishi LU2-4400 for $380.00. Machine looks and sews like new, bobbin winder, thread stand, table all excellent shape. Can't wait to try it out on some practice work.

Hello everyone, I new to all this, although years ago I did do a few re upholstery projects with an old Kenmore (tuff old machine) but now would like to expand my horizons as I am getting into the "later years" . I have always been a firm believer in buying tools suited to the job the first time as there is now economy is junk, so I now have a choice between two fully operational machines. One is a Mitsubishi LU2-4400 and the other being a Reliable MSK-8600B. I would like to sew heavier gauge vinyl for tractor enclosures and do a bit of cloth upholstery as well as some leather if my skill level progresses before I die of old age. I could have either machine for $400.00 and from what I read they are both good for the task, but is there a better choice in terms of performance or serviceability/parts? I'm not going into business, just want a good machine that will do the job without a struggle. Tom
