As a JC Sports boy (only say that due to the large JS Sports Window Banners on my front and back of my SVX) I have heard some really good things about the N1 Pulleys. In fact I am headed down to JCS on Wensday to get myself some. Was in there last week and they said they should be sometime this week, hope they are. You can check out there website or call them direct at 720.898.0948
And by the way it must be replaced, you can not simply push it back. Good Luck.
