1966 230SL. I am considering replacing the Rocker Pin (ball head) in my head, as well as the rocker arms and cam. First things first is removing the Rocker Pins (and I haven't begun to try to remove those yet). It would seem that the better approach would be to have the aluminum head hot or warm, making the threaded hole in the head a little larger since aluminum expands greater than the steel pins.
And since I read that removal can be such a challenge, I am considering a pneumatic impact wrench with the 6-point socket. So I am interested in hearing from the Forum on experience others have had with this particular job. (Is it covered in the BBB?) And what is the tightening torque on the reinstall? Any sealant on the pin threads?
Advice and actual experience would be much appreciated,
Harry
