Motomike I got the screw out ok with some extractors. Nice tool you made there! What I am thinking is machining a large washer with a clearanced area for the shaft on the backside. This way a thin after market sprocket will fit fine and you still compress the oring making a good seal on the inside. I can then use a star type lock washer that really digs in. And a longer grade 8 or 12 bolt. Longer isn't really any stronger but it does give more area for loctite. This way you get the torque needed for the o-ring and the security of the lock washer. The oring's compression is controlled by a step in the bushing. It can only get squished so far before the bushing bottoms out. This happens long before you flatten out the spring washer....unless it is installed backwards or it is completly worn out.
