JDFanatic:
Thank you for your inquiry on the PTO shaft and sorry for not posting the outcome, I got a little bogged down in work-related matters. I am impressed by your ability to keep up with so many posts and your always-valuble feedback and suggestions. In any event, the service dept. at my dealer advised that an "off-axis" measurement at the end of the shaft of under 50/1000ths is "within tolerance" and not a cause for concern. I figured mine to be around 40/1000ths give or take. Also, ran the rear PTO shaft with no load for multiple tests and never detected an inordinate amount of heat due to bearing damage or displacement. In the end, while it looks a little freaky, I apparently freaked out more than necessary. One reason that I thought it was worse than it is at first was because, when I took my initiatial "off-axis" measurements, I neglected to divide by 2, which my method required. I eventually figured that one out on my own and was greatly relieved that the off-axis was not the roughly 80/1000ths I initially thought it was. I will always keep periodic tabs on this, but it does not seem to be an issue at present. I am a little bit of a perfectionist and maintenance freak though, and something like this could really drive me nuts if I let it.
Best regards,
Lou
