[Scott, Thanks for your advice, I hope to get my new pinions in the mail right away or I would. They were ver nice and sent it free. I just have to take it apart, clean it and put it back together. Thanks again. GaryQUOTE=Scott Hackler;74409]Gary, I had experienced the same this on my SuperNova2 chuck. One of the tightening spots wouldnt work at all (stripped ?) so I marked it with a sharpie to save the frustrations later. I meantioned this problem on SMC's forum and was told to cut the ball end off of the t-wrench, because the wrench was what was stripped out. I did exactly that and now both tightening spots work exactly like they should.
