I have my lower crank pulley cage off the car. It has some play from front to back. I did some searching on Google about disassembling them and couldn't find anything worth mentioning. My first question is should I be worried about the play? The pulley itself is fine. It's the inner part that screws into the crank and the part on the outside that has the 3 studs that go into the rubber on the pulley. My second question is how to take it apart or tighten up? Thanks.
