I bought a long handle box wrench at Harbor Freight for this job. It was far from a perfect solution.


2) I hope I am in time to help. The spinning nut is easily rectified by getting the largest screwdriver in your toolbox. Place it vertically next to the cam bearing tower and let the shank of the screwdriver impede the CW turning of the hex nut. This is a clean solution and does no harm to the mechanisms. I am not going to discourage you from buying a third wrench from other enthusiasts. I assume they will work also. I am meticulous and the interposition of the screwdriver shank worked for me.

Good Luck,
