Question about Janome MyLock 634D Mechanical Sewing Machine

Lower looper needle broke

Machine was working great when the lower looper broke,i was informed that it was because the timing was out, my friend who is a mechanic has been for thirty years knows he can replace the looper, he thinks the reason it broke was because the screw was loose and had nothing to do with the timing,as it had been working great, please help with a solution, is it possible for a person with a great deal of mechanical knowledge to do a home repair, thank you

Well, first of all, while it might be possible, I highly doubt it.
More then likely the timing is off. There are several adjustments that need to be made correctly or you will end up with more problems. Your best bet is to take it to a qualified service technician.

I have a funlock 004D/004, the lower looped broke and I replaced it with one I ordered online. It makes a chain when I run it but when I try to sew fabric nothing catches. Any suggestions?

you have to make sure the looper is properly positioned. With the screw loosened slightly you should be able to move the looper up and down slightly, thus adjusting the timing. You are looking for the lower looper tip to come in slightly above the needle eyes, as close as possible without touching. Then the upper looper must come in right behind the lower looper "head" as close as possible without touching. The upper looper should then extend past the left needle by about 2-2.5mm, and the needles will come down before the eye of the upper looper returns to the right.

Broke a needle, replaced it. Now stitching is all wonky. Rethreaded many times, changed both needles. Adjusted upper and lower loopers. Nothing is working. Worked fine until the broken needle

Um, possibly the machine is out of time--happens frequently when needles break. You can search the internet for sewing machine timing or take it for service.

Thread broke on bottom looper the first time out of box i had to try and thread and the tension was still tight The bottom threads were not stiching

I'm going to assume here you're talking about a serger. Unthread the lower looper and the eyes of the needle. Set the lower looper tension to 0. Rethread the lower looper, then the needle eyes. Then reset the lower looper tension (try about half a number lower) and see if it chains. If it won't chain, try replacing the needles.

Correct threading for 4 th. Juki ind. overlocker

Overlockers and or Sergers are ALWAYS threaded the same way. Upper looper, Lower looper, right needle, left needle. If you have a model number for your Juki we might be able to find you more information.

The best way to figure out tension problems is to thread each thread in a different color so you can determine which thread is giving you problems.

These machines can be frustrating and EVERY time the thread breaks you MUST start the threading problem from the beginning... upper looper, lower looper, right needle left needle.

Bernette 334D bent lower looper

The bent looper needs to be replaced. It is also very likely that the machine has been knocked out of time. Professional service may be needed to get it working again.

Timing on a Huskylock 535D surger

the eyes of the needles must line up with lower looper as they pass (timing) the distance between the needle and the looper must be exact. No distance between them and not touching. yep, that tight. they shouldnt move the needle even the slightest amount as they pass each other, yet no space between them.

Lower looper

It is impossible for a looper to come unthreaded if you are holding one end and the other is still feeding off the spool. Somewhere a thread broke - must be either the upper looper or the needle. Try completely re-threading your machine. Many machines have an "order" they prefer to be threaded. Try starting from the right tension guide and work to the left.
