I just love how clean everything looks. Bummer that you have to open it up, but at least you get to look over everything involved and see if anything else is showing signs of stress. A chance to build it up stronger, that is some horsepower you have cranking it all. :(

hopefully case and shafts are good? Good luck! Always a bummer when something fails. :confused:

It did not do a major blow out.
Trans still functioned just not correctly.
Everything should still be good except for whatever is the failing part.....hub....thrust bearing...ect.
This was not a rev it up and dump the clutch thing like drag racing is.
More a gentle accel the drum in 1 and 2.
Get into 3rd and get it stable and at an rpm you think you can start at without bogging. Basically as slow as you can go in 3rd without chugging and pinging. Get stable aaaand....start recording......and nail it. No jerk, dump, snatch.....just as hard as it will dead pull.
Computer calculates the rate of acceleration of the heavy rollor.
I spun it 132mph in third gear.

Time to think about tire speed ratings? Don't want a tire exploding even on the dyno. :xzqxz:
-
All 3 are 130mph rated tires.

I have the gear stack out and on the table.
Not yet tore down. Just by a visual inspection it looks like 3-4 hub and/or slider is not round.
The big thing is both brass syncros are broken into several pieces.

Ouch, broken synchros, that is going to hurt
-
could it be a shaft bending under load , or a worn hub/gear tooth profile allowing the partial disengagement in
3rd gear? doesn,t sound like it popped out of gear, but some sleeve or bearing allowing 3rd gears/hubs to rattle around?:confused:
-
It looks like the hub twisted.
It is not as hard as a gear.
The gears and shafts will take it.
The syncro hubs are what connects the gears to the shaft.
-
hopefully there are stronger hubs available.....I had thought that a loose pocket bushing/bearing or loose countershaft front bearings, or worse yet spreading case bores could let the 3rd gears get loose....a bad hub is actually maybe the best news you could get!...at least that would explain the broken syncronizer I suppose with a direct 4th gear tranny 3rd is the weakest gear, but the gear that catches most of the grief....just the way it goes...good luck...hope you can make it stronger!
