Message: [QUOTE="mandkole, post: 1114298, member: 4630"] at Gates, we call the tensioner inspection 'spin-cycle'-- 1) spin the idler and listening for unusual noise, dry bearings,etc. 2) then, cycle the tensioner arm back and forth, feeling for issues with movement or alignment issues. The tensioner may look OK at 'free arm' position (no load) but will begin on misalign as you load it up. As tensioners wear, the pivot bushings wear and cause misalignment of the arm to base. The factory tensioners on the 7.3s are not high content parts and dont have a lot of life. They usually develop issues by 3 yrs/ 75-80K. A good running tensioner and well designed layout should have almost no arm movement as the belt is running on it. [/QUOTE]
