When I replace my drive belt last night, I did check the belt idle rollers and the tensioner roller. I can feel some plays on one of the rollers when I grabbed and shaked it. Also, I realized that there is a whinning sound that is coming on that particular roller. If I am going to replace one, I rather replace all of the rollers. Is anybody knows what direction (clockwise or counter-clockwise) do I need to do to unbolt (untighten) all rollers? I do appreciate your help, thanks.
