Thanks for jumping in on this thread. I've read many of your threads / posts on this forum and have respect for your expertise and experience. I read through your entire thread on the DIY belt rewrap. So what I'm coming away with in the end is to to remove my (bad) idler pulley and then properly (grade 8 bolt, etc) mount the new idler pulley down in the existing hole above the alternator. That is the end result of the re-wrap thread as it concluded . . . RIGHT? I realize that your intent was to get a better "wrap" on the S/C pulley to prevent slippage.

My focus, however, is to prevent future failure of the idler pulley. The failure issue with the idler pulley is caused because it simply spins at too high RPM and a premature bearing failure is imminent. I don't see how moving the idler pulley location changes anything to address the idler pulley too high RPM issue?

It would seem that the currently available Waldig / Needswing pulley saver kit better addresses / resolves the idler pulley premature failure issue by eliminating the idler pulley and substituting larger pulleys that will spin more slowly. Am I getting that right or am I missing something?
