The focusing ring of my Summarit 50 f1.5 is very stiff and I have successfully dissembled for lubrication except the retaining ring as shown. I unscrewed the lock screw and tried to unscrewing the ring anti-clockwise but unsuccessful.  Does anyone know the unscrewing direction is anti-clockwise or clockwise? Thanks a lot.

this is standard, clockwise thread (unscrewing counter clockwise). You will need spanner (left photo) On the right photo focusing mount in parts. This is Xenon on the photos, as far as I know mechanical construction is very similar if not the same

Thanks Jerzy. I believe they having the same mechanical construction.  Your photo is very helpful. I have similar spanner too but can't unscrew the top retaining ring.  I'll try it again may be let it soaked in alcohol awhile. Thank you very much.
