<p>Great article! It worked for me!! Although an old post one one wee tip….to get the front rim off use a rubber stopper, they can be found at beer/wine making stores and come in assorted sizes, they're usually a buck.</p>
<p>Indeed the little ball bearing/detent is TINY! maybe a single MM so its easy to lose, it took me about eight tries to finally seat the aperture ring with the bearing in place so don't give up hope.</p>
<p>Again, thanks for finding a solution to the puzzle, my 35CV is perfect again!! :-)</p>
