I've bought Durst L900 several years ago, but it went with a small defect in the lifting mechanism.
There are a gear in the head and a gear plane (is that a correct term?) on the back of the column. They both got broken teeth.
Decided lately to order duplicates for both parts and put the enlarger back in order.
Well... I can't disassemble the head much enough to take the gear off (;
I've read service manual in French, but didn't find the answer.
Can anyone advise?

Details so far:
1a and 1b — stuck.
7 — no idea what this is, but it doesn't look like a screw.
6 — sits tight, can't take it off.
3 — apparently not a screw.
