Hey all, my Idler Wheel (on, or next to, the belt tensioner) is squeaking to beat the band!!!! Can the idler wheel be EASILY changed out or do I have to buy a whole new belt tensioner assy? By easily, I mean simply: Can the thing be yanked off and put back on with nothing but the most basic of tools (like an open end wrench set)? I can't see the back side of the wheel, so I don't know if there's a bolt or nut back there or not. If it's a simple: "Remove bolt (or nut), Replace wheel, Replace bolt (or nut)" type of deal, I've got no problem doing it. Can someone tell me what I need to do?
