Adler 169 373 a couple of issues

[milkman]

Hi,

I ve started reconditioning a Adler 169.

The machine didn't had oil for a long time so rotating it by hand was very hard

I disassembled the feet and needle linkages completely and cleaned them but haven't yet assembled the parts. I ve also disengaged the timing belt. 

The machine is still rotating hard. Then oiled it a lot and started rotating. It seems to improve a bit.

Question 1 : timing belt disengaged and only upper shaft, the hand wheel makes about 2-3 full rotations when letting it go after giving it some momentum. Based on your experience is this in spec or should I look into the cleaning of bushings...if I ll be able somehow to remove the upper shaft.

Question 2: does somebody know the nominal distance between the presser fot bar and walking foot bar in 0 position for the stitch adjustment? The issue is that setting the stitch length to 0, the walking motion was still there. Not sure if I understood correctly after browsing the forums, but this can be adjusted from the connection of the rocking arm shaft and the other linkages found inside near the stitch adjuster, and this can be fixed by knowing this standard distance between the feet bars.

 

Thank you!

Thanks!! 69 class, makes sense...similar stitch length lever.

Now it s clear for me. just to adjust the cam where the fork goes until I have no movement. Fingers crossed! 

By the way, do you loctite all the screws you open after making adjustments?

 

Allright, I will assemble everything and oil everything again and try to rotate by hand and I will post an update.

The service manual.is gold! The german one for who speaks/understands or google translates is even better.

I fully reconditioned my machine, painted it and found an original Adler table which I reconditioned it as well. Waiting for some needle plate and feet, but it sews perfectly.

Attached a pic from.when I was doing the timing of the feet and needle.
