Subject: Re: Fan adjustment meadows S4 engine
Unfortunately this assembly was removed from my engine by the previous owner, however it sounds very much as if the boss with holes is an eccentric mounting, with the "locking bolt" being a pinch bolt.
Assuming there is a gap in the "pinch" area, I'd run some freeing oil in there & let it soak in, with more applications if necessary over a few days. Try again & if no joy, use a hot air gun to expand the aluminium...as that expands more than steel, it should loosen its grip. Doubtless electrolytic corrosion between the steel & aluminium...it can stick them together pretty firmly!
