Heres the sequence I used to repair the eyepiece, the broken brass pin on the rear element housing was the problem due to grease solidifying. Theres a couple of rubber O-rings not shown but if youre taking one apart you'll see where they are located. Getting the helical movement in the correct orientation compared to the rear element housing needs to be correct as there are 3 possiblities, but you will see the correct one that gives full rotation. Theres one brass pin with pvc collar not shown, it goes in the straight slot at the base of the helical movement and locks the helical movement in place.

If anyone wants to know the complete dissassembly proceedure I can post the details here. Common problem is shearing of the internal brass pins due to the locking up of the helical mechanism. Wrong choice of grease by Baader, they should offer compensation.
