To tighten the pinion shaft nut..the one under the speedo drive.
I either did not tighten it or it came loose.
Apon removing the gearbox I could not turn the output shafts by hand. They were that tight.

Here is the bad:
most of gear stack ok, maybe 1 gear got beat up

R@P trashed.


Here is the good:
I found out how cool and willing to help people are on this forum.

Call webster I created some new cuss words.

I Found out RedLine gear oil is not the right oil for our gearboxes. Lucky for me I found out before it trashed my gearbox

I am reminded again how lucky I am to have a lift.

Nobody else who have read this post, is going to leave this nut loose.

I'm very lucky I only went about 3 miles and was going slowly to check things out.

Yuck, what specifically happened? Did the nut come lose and then ripped into peices all the while killing the gears?

Also a picture of that "nut" for us ignorant ones would be awesome.

Thanks

Nut that came loose...
Its the black one.
With this loose the gap between the R&P is no longer controlled.
And they are allowed to come in contact to each other. There really was no chunks in the oil when I drained it. Just a little metalic looking.
Not sure how the gears on the stack got damaged. I would guess when the R&P was binding it put extra side pressure on the shaft and then those gears rubbed each other the wrong way.

Many future gearboxes thank you for the warning.

Good luck with getting it fixed.

Ah, thanks, I was thinking directionally "under" the speedo drive which put it on the intermediate plate, below the gear which didn't make any sense. Now it makes complete sense.

Thanks for the help!

I'm really sorry to hear that, man.

Fortunately, you have the workspace and knowledge to repair the damage, but that's probably small comfort at this point.

Bolt, not nut. Damn. I remember tightening it, it was the last stack I did. Very odd. I must be remembering incorrectly. Luckily, this is not going to be a too big of a deal to fix. What I think would be the best bet would be to send me that gear stack so I can harvest the parts from it, and the gear stack from your new core so I can do the transplant, then I will send you back the correct rebuilt unit to install and be happy with (on my dime of course). You will need to reseal that new case so I will send you a kit and instructions if you dont remember the little tricks I taught you form the clinic.

Lesson learned: From now on I will be doing QA on all bolts and nuts on the stack before it is certified (me doing the check, no assuming that someone else did it). I will have a check sheet for the next clinics to make sure that mistakes are not made. Between you and Eric that is 2 too many.

no way dude! IIRC, I was right there when you tightened that bolt. We even had to look around for the "Evil" tool. I'm getting scared now for mine? I haven't installed it yet.

Edit: Wasn't the last stack Larry (Larouex)? he had to go back and get his trailer from the campgrounds. I'm pretty sure I remember that cause he was using that welding table for a work station.

WOW!! That really sucks.

Good thing you got that Redline out of there or you could have had a real problem on your hands. . .

If you need any parts I have a couple left overs.

The bolt must not have been tightened. John and I talked and I am taking care of him

My alternative hypothesis is that the GL4 Redline caused the bolt to loosen and come out. Ya, that sounds good, er, removes all responsibility from me

Drew, man up! 98% of the time my rebuilds are right all the time

Dr. Don't beat yourself up too much here. You adjusted my forks after over 12 hours of work, and we were all tired.

BTW: It only took THOMAS about 10 minutes to adjust and tighten the shifter fork. Since then I have put a couple of hundred miles on my car, and it shifts beautifully.

I posted some pics on Sunday that I took over the weekend driving Mulholland Drive. Again, my thanks!!!

I'm going to install it after I remove the motor and do a little house cleaning in the engine bay! To busy getting the house and yard ready for winter. It had already snowed here this past weekend. I trust you Doc! It's just my bottle of vodka looks a little emptier than I first thought! I may have drank more than I previously admitted too, to busy having fun and working

Ah, its not IF you make mistakes, rather it is WHAT you do afterward So far nothing insurmountable, just preventable PITAs.

I would agree, And thank Mike for the way he has handled this. He is going way past what I feel he needs to to take care of this.

I feel it was ALL MY fault not his. This was a clinic on how to do YOUR trani. Not have someone do it for you. I was just a dumbass and was not paying enough attention to what I was doing. I prolly got a bit distracted right in the middle of finishing my stack., running around being host and helping folks with torches and tools and whatnot. The 3am hangover prolly didn't help any either. Shit happens.
Thanks to Mike for the helping me take care of my F-up.
Next summer when I am bang'n gears I'll have forgot all about it.
Cheers and maybe I'll see you next weekend, Dammit, I have to ride my Ducati.

Damn gremlins! I hate those sombitches! They get me all the time. your still the man Doc!!!! even if you do use all three toilet paper rolls in one night!

That still amazes me!! The crew went through almost 5 rolls of butt wipe in 2 days!!!
Thats allot of bullshit I might have to look into getting my septic tank pumped...

It wasnt me! I was the victim here. When I went for my 10th or 11th shit I found that it was all gone.

Wasn't you. It was the atomic buffalo turds. My fault. They MADE you do it.

Can't forget the clams, louisiana hot links, ribs, corn and the waffles! All that was one hell of a gutt check!

fiber is good.
