I did manage to get the foot bar holder off. I have determined a couple things. The foot bar holder should sit on the bushing where it’s set screw will bring the slot marked by yellow in the picture. This keeps it in place vertically but allows it to turn around so you can sew in different directions. The piece circled in red is the bushing. If the foot bar holder is set by the slot then to adjust it up to where it engages to make the foot walk the bushing must move up. There is a set screw on the side of the head that reaches the bushing. This makes me think it should be adjustable. However, I can not get it to move. Has anyone ever moved that bushing?  If so am I missing something besides the set screw?

If the machine works w/o removing the bushing better leave it where it is. If you break something there will be no replacements parts for these old Dürkopp patchers - or - if you find  them - they will be not cheap.
