yes and no
I can see how drawing it up too far may cause them to crack but.... "too far would require some crazy amount of torque. I do not know the correct torque setting but I have overhauled hundreds of bikes new and old and never gave it a second thought about adding light grease to pretty much all metal on metal contact. Even without some lubricant I'm thinking one could find a way to over-tighten. Then again, I could have been doing it wrong all these years.
