Thank you Uwe for posting the Adler 167 manual. Is there such a manual for adjusting the 267 class machines? I have a 267-373 machine. I was able to download following:
Durkopp Adler 267 Instruction for service (In English). This 26 page document ha further seven pages of photos and diagrams of parts.
Is there additional information for adjusting this machine?
I watch your excellent videos on adjusting various Adler, Juki, Tacsew etc. machines and gain understanding of the basic mechanisms of how the upper and lower shafts are interconnected: how the needlebar oscillation is tied with the feed mechanism: how the pressure foot and oscillating foot are actuated and how to adjust their heights etc. And I would like to thank you for effort in making the subject easier to understand. I will request you to throw some light on how the reverse mechanism on Adler 267 and Juki LU 573 (or Tacsew) work. I have found no clear drawing to study to understand the interplay of the parts.
