Re: Richardson article.
Before removing the engine perform both a compression test (air gauge in the plug hole) and a leak-down test (air pressure into the plug hole) on each cylinder. Once the rockers are off it's impossible.
Never apply pressure to the outer ring of a damper. Hammering the inner hub should be done with the crank flange on the floor, or firmly against a substantial back-stop such as a steel door. Otherwise, you're hammering against the thrust bearing.
I'd replace any bearings with more than .003" clearance.
