Yeah. It just seems to me that they want the end user to have sense enough to know what they're dealing with more than anything. They're not saying Yes or No one way or another but just "might be acceptable". Which I still take to mean that the end user of the bearing is responsible for being smart enough to make a judgment call. I agree; if there was any doubt just replace it on a cheap bearing. But again, it all comes down to a personal judgement call, for me anyways. Can you post the failure analysis documents indicating bearing staining is a first stage indicating overheating? If so, that will be an interesting contrast to the SKF document as well as the Timken video I posted.
Maybe I have been lucky, but I can't recall a single time I have ever had a tapered roller bearing fail on anything I've ever messed with that uses them. I had a T56 pilot needle bearing explode and wreck an LTx T56 input shaft. I have ONLY run pilot bushings after that. And bronze ones.... I check them with a magnet to be sure they're not iron bushings, that's no bueno for a pilot bushing.
Do you care to weigh in on preloading the bearings a tad bit as opposed to having endplay like I mentioned a ways up? I have found multitudinous posts on LS1Tech where guys are setting them up with preload. Which is directly contrary to what Tremec publishes.... Here are some I found easily.
