They had several different styles prior to the screw together type.

As mentioned, inside there are friction surfaces that act against each other. When new they worked great. As they age they don't and the motors become harsh. The whole shebang is held together by a selective spacer under the pulley.

I have never seen service data on them and the only way to do them right is in a laboratory.

That's all I know. I had one case where I needed information and none was available, so I set the thing up as best as I could reckon. Other cars the units were still in one piece and I left well enough alone.

Pull the motor if you want to change the timing chain, and clean out the camshaft galley as well.
