Cupomeat is the talent behind my rebuild DVD not sucking and actually being entertaining AND informative. He did all of the work other than what I did in front of the camera. Wouldnt it be, that the transmission that I rebuilt for his Dad's early 911 would be the first that I have ever seen break a pinion after rebuild. Of course, it was a more rare and expensive 8 toothed pinion as well (IMG:style_emoticons/default/dry.gif)

I was a bit confused on how this happened, but it was the obvious failure and matched Meat's description of events.

Tonight I was able to get more personal with the gear stack and soon realized that there was more to this catastrophe. I first noticed that the carrier for 1/R slider was badly galled and chewed up on a face that should not have any wear:

Then I looked at what it rested against, the 1st gear race and bearing. Holy shit. The bearing fused and locked up first. Oddly enough, 1st did not break and the pinion did. This may be because the pinion is weaker having more teeth than our 7 toothed variety. Strange stuff. No idea why this happened.

I had to beat the gear off of the race, which looked like this:

I still have not been able to get the pinion out. I will have to cut the race as it is all kinds of messed up as was the end of the pinion. What a crazy failure. I am glad that this was the only I have seen in a rebuild in 10 years. I have found others in cores, but these were neglected cores.

Gonna need some parts (IMG:style_emoticons/default/smile.gif)

You can say that again...

I think next time, you should start drinking before you start building, then.

Looks like classic Fetzer Valve failure. Nothing you can do about that.

The springly sprocket encabulated. I just need to realign the eddy current transfuser and it will be fine.

Can the above mishap be caused by incorrect tolerance during rebuild and or wrong gear oil?

Yes, but these were not factors encountered with this rebuild and run.
