Please help, thread is too tight when pass bobbin

[Orrrmygod]

Umm I have no ideas where are tip of latch, groove, clutch bushing and the spring.

Look like mine (PFAFF 345H3-6/01-CLN) doesn’t have safety clutch or might be in different position. It’s quite different from the movie below

Your machine has no safety clutch!

Hook is no longer spinning - looks like you have loosen some screws on the hook driving gears. I guess hook is out of time now (too).

I did not say thread goes the wrong way. I said it seems to be hanging somewhere between the small tab of the bobbin case and the notch in the throat plate (tab sits in the notch) and your bobbin case opener is NOT opening the bobbin case to let the thread pass between the small tab and the notch in the throat plate.

So my guess was that you only have to adjust the bobbin case opener - thats why I linked the video.

Hard to assist you from the distance if you don´t know anything about sewing machines. I would honestly recommend that you go to a sewing machine technician for industrial sewing machines.

I was thinking about the gears having come loose, but stopped because I thought there might be a clutch. Hopefully, the hook drive shaft is keyed for the ring gear. Timing it will be a fun job for someone new to this kind of machine. 

Just a tip. Orrrmygod,  if you are within driving or shipping distance of a knowledgeable industrial sewing machine dealer, they might could replace the worn screws, tighten everything down and retime the machine to get it sewing again.

Hi Wizcrafts, FYI I recently replacing the motor and speed reducer. Please see attached. I hope they are not causing the problem. (There’s no belt when I took the photo.) I’ve been using it and working quite well.

The motor/speed reducer shouldn't have anything to do with your problem. From the look of your video the gears are out-of-mesh underneath the shuttle. You have two choices - as has been mentioned find a sewing machine mechanic who can fix it or, if you insist on doing it yourself, spend a LOT of time reading posts and studying various manuals of similar type machines because you need to be sure you understand what you're doing.

There is a limit to the advice people can give via a forum and mostly it assumes a reasonable mechanical knowledge on the part of the person with the problem for anything other than simple issues - and this is not a simple issue.

Thanks a lot guys, I took the machine to mechanic this morning. I can’t wait to get the machine back and start to make something soon. Check out attached photo, my hand stitched wallet.

Probably a smart move, I think. Stitching looks good on the wallet.
