Today at the junkyard I found an engine that someone started taking apart, so I finished removing the camshaft to learn how they are put together. Seems like the distributor pretty much has to come out as well. Anway, yes I found that once you have the camshaft out, you can pull out the follower cups with your fingers. But it is frustratingly difficult to separate the shims from the tops of the followers. I had to use the point of a utility knife to separate the shims at those little notches cut into the top rims of the follower cups to get them off. Now I have 8 spare shims and am familiar with how these things come apart.
