Yes, I have the cam sprocket off, and the retainer piece above the camshaft. I guessed that I would get it out with a little bit of wiggling, but there is resistance at all points along the 180 degrees of rotation. I was hoping that at some point in the rotation, I would get some movement outward, but I don't. I"m going to try some additional lube on the bearing surface and see if that makes any difference. Thanks.
