Need help with Adler 167 Maschine fixing bobbin bar

[Karlluis]

Hi everyone, 

Yesterday I bought a old Adler leather Maschine at a Atelier closing which need for my studies… it’s been standing for some years so I bought it without really being able to try it out( it was quite cheap).

after trying it out I noticed that the bobbin is not turning. Turning the Handweel (which was already very hard) only makes the metal bar in part 2 turn ( referring to the picture provided) the longer bar and everything after is not turning. I tried turning it by force thinking it’s stuck but even after turning it by hand a couple times it didn’t change. I also tried opening the two bolts (2nd picture) but they are too stuck to move. Before I have to carry my machine to the mechanic I thought maybe someone else had had this problem with older, longer not been used Maschines and can help me. I’m usually quite handy and fix all my mashines myself but I’m out of ideas here… thankfull for any help! Thanks

I got 1 question. When you turn the hand wheel? Does the connecting belt on the right side turn with the hand wheel? 

I am no sewing machine mechanic. But I am Diesel technician.

Thanks.

I circled it in blue. Does that turn with the hand wheel?

BTW - the timing belt appears to be in bad shape form what I see it should be replaced.

Looks like the safety clutch is engaged but maybe it disengaged for some reason anyway this is how to engage it again:

The safety clutch has to be tripped.
