Thank you very much. Exactly what I needed to know. Going to print it out and put in my
shop manual. I didn't even think of checking the cam ring and there is definitely a pretty deep grove. knowing I can just flip it over and not having to buy a new one is a great hint. Also not using white lithium grease is a good hint. I WAS planning on using it as it doesn't harden as much as black grease. I'll just use some P.B. max and not the P.B. blaster penetrant on re-assembly.
That thing hasn't worked right in so many years. If I had only known how easy it is.
