Hello everyone,
I bought a used Juki LS-341N for my Leather working Business 1-2 years ago, and it has been a great machine so far.
Recently, I made a mistake when sewing thicker material, and it seems I have broken the tip of the Hook next to the Bobbin, so the hook does not properly catch the upper thread anymore.
I have tried to resharpen and reposition it so it can catch the thread again, but to no avail. When I position the hole sled with the bobbin closer to the needle, the needle hits the side of the bobbin and is bent away from the hook. So it seems the Hook is too damaged that it could be fixed with sanding and readjusting.
Luckily, the original seller sold me a new sled (the hole bobbin shuttle with the Hook).
Now I have contacted a mechanic who would be able to do the replacement and service, but they have not been very responsive. (I am located in the Southwest of Germany and have not found other options except this person)
So I am trying to evaluate how hard it would be to do this myself. Changing the part does not seem too difficult, but adjusting the needle hook timing and the exact hook position has very small tolerances, and I am not sure how well this can be done by an "amateur".
Do you guys have experience with this, or could you give me an estimation of the difficulties and pitfalls of such a task?
Any help and input would be greatly appreciated!
Cheers
Josh
