The focus helicoid is a multi start thread, which has to go back in the same place as it came apart. Did you mark the two parts as the helicoid seperated?

Screw in the small ring, all the way in. Now turn it back, one full turn. Pull the optical block from the helicoid, and start trying helicoid positions. Eventually you will find one that comes close to catching onto the focus guide, and when you do start playing with the helicoid and bottom ring until you get guide into the slot. Screw the helicoid all the way in, and pop in the optical block. If you get past infinity, you are good. Now disassemble and repeat it with grease Smile
