Need Help With Adler 167-373

[Dave9111]

Ok... looks like I need to compare parts lists. 

A very good idea!   I'll report back on the results of that.

Thanks for pointing out your Ebay store as well.

Switched to a 92 bonded polyester and what im experiencing now is the top thread snapping on the first go around.  Pulljng most of the plate area apart it appears the top thread is snapping just below the lower plate where the needle goes down into.  Does anyone have any thoughts?  What im thinking is the thread is getting caught on a burr on the lower plate, but I don't see any.

[Dave84]

I'm also thinking could the thread snapping have something to do with the first loop?

Hi Dave84,

What machine is this ?

Have you checked your needle plate, feed dog for burrs?   Needle strikes on the edge of the needle hole can cut the thread.  

Another possible issue:  If you don't have  a sufficient gap around the nib on the bobbin carrier that engages with the needle plate. 

There is a nib (I don't know its real name) that hold the thread on bobbin carrier to form the loop around the bobbin carrier.  (The bobbin carrier is held stationary inside the rotating hook by this nib)

That nib engages in a notch in the needle plate and prevents the bobbin carrier from rotating so the thread is pulled out of the bobbin carrier. 

If the clearance between the nib and the notch is not sufficient, you will break your thread every time.   This happens if you run large thread through a machine setup for thin thread. 

The only way I know how to set this gap is to move the hook away from the needle plate.   I've never had to do that.    Was the hook replaced in this machine?  If so perhaps the gap was not properly set?

Ahhhhh... I had the thread backwards through the needle.  Thanks to Uwe' s timing adjustment video for allowing me to spot that.  Once I put it through the last guide hole on the left of the needle then through the needle toward the machine, I have perfect stitches.  I do need to adjust the tension on the bottom, that just pulls right out after I stitch and cut.

Thanks for the input Dave but it was a stupid mistake on my part.  I had the thread through the needle backwards.  I'm looking forward to testing and adjusting tension to start a pair of custom pants.

I have miss-threaded sewing machines in so many different ways.....  

I tell myself I do that because I am creative.... but that may not be the issue!    ;-)  

[dikman]

You're not the first to do that, and I can guarantee that you won't be the last!

[Dave84]

I'm sure.  I tested before leaving for work and every run was solid.  Made my day way better.
