I know what you mean lionel. All I was trying to say is that based upon my experience, I would make a personal judgment call saying "hey this bearing is certainly not brand new any more, but I wouldn't hesitate to keep it in service longer". Tapered roller bearings are pretty damn tough from my experience with them.
It doesn't matter though because that box is shelved for future use in another project. Maybe I will replace the bearings then who knows? Honestly, I probably won't though. I'm not afraid to run it till it breaks because I have the tools, knowledge and skill to fix it when it does. I typically run things as far as I possibly can no matter what anyways. One of my daily beaters is a 97 F150. It's been a great truck. But with literally 350,000 miles on it, it sounds like a metal coffee can full of drywall screws when you start it up on a cold morning. I'll be surprised if it doesn't make it to 500,000 miles!!! My personal "secret" if you will?? I make my own "blend" of oil by using mostly 15w40 diesel oil with a splash of ZDDP additive. OVerkill??? Probably so. But why the hell not?!?
I found this from Timken:

Pretty cool. Maybe to you, that bearing looked worse than it was, but like I said, In my opinion, and from my experience it was not something I would even worry about. It didn't look like any of the bearings shown in that video. That's for sure!
Like I said though it's irrelevant because for this hybrid T56 I'm building I just dropped in the entire internals from a NON Z06 T56 for the triple/double synchros. It was just easier than way. Plus, that trans only had about ~50K miles on it so that was another reason I chose to do it that way.
I don't want to surround myself with "yes" people and those who think exactly like me. How fucking boring would that be? I respect your difference of opinion/judgement call/perception whatever you want to call it. Please respect mine. We're all on the same team here. Should be anyways. I know what you're saying though. What I've been trying to say for a while though is something like this....... My style is a lot like sloppy mechanics.... If you don't know about this, please google it. His motto is "I'm giving hot rodding back to the people"
For anyone who might not be familiar with sloppy mechanics just check these videos out:

This ^^^ I love. I spent so much time reading and reading while I was piecing together my S475 LQ4 setup that lives in front of this T56. I copied as much shit from the internet and sloppy as I could because there is really no need to reinvent the wheel. It has paid off. That truck is the fastest car I've ever owned/driven. When I push the pedal down far enough it spins, 1st, 2nd, 3rd, 4th, doesn't matter it just spins. It consistently points the nose towards the ditch on the right hand side. It was enough to make me shit my pants the first time I really uncorked it. But that's my style man, do what you can with what you have, even if it means reusing rusty junk. Most people around here see this truck and probably think "oh look at this shitty farm truck". That really isn't far from the truth, but when I smoke their ass in a clapped out truck with the aerodynamics of a barn door it makes me giggle like a little fucking girl. I haven't found anything on the street that has beat me but I'm sure I will. Or maybe not? It depends on how much I crank up the boost and whether I decide to keep the tires on there that spin because it's fun sliding all over the place or switch to something that will actually hook up. A couple of the local street rats challenged me to a race. I said Sure! Let's race up the twistys to Hennessey and back! (Town north of here). That shuts them right down! They can think for '1320 feet and then that's it brain shuts off.... Those cars would kill me in a drag race. But I would absolutely dominate on a long range bombing run, and be more comfortable with double overdrive, power windows and locks, plush interior and sound deadening, sound system, CUP HOLDERS LOL you get the idea. Everybody around me is stuck in the past in a lot of ways: carbureted big blocks, powerglides, way fucking loose converters etc. etc. That stuff is all cool don't get me wrong, but not many around my part of the world have embraced the advantage(headache) that is EFI and LSx.
Lionel: The factory (Tremec) endplay specs for the T56 is .000" to .002" endplay on the mainshaft, .000" to .002" preload on the countershaft, and .000" to .002" endplay on the countershaft extension.
I have set the main and counter BOTH to a preload of .002" this go around. I will likely do the same for the countershaft extension. To me it makes more sense to preload them to account for the case expansion. And being a tapered roller bearing preload is a good thing IMO. Endplay is not. I set that OTHER T56 up to Tremec specs when I converted it from LTx to LSx. I'm going to experiment with a slight preload all the way around this time. Many guys on LS1tech talk about doing preload on ALL of them.
