Small update from me
I took the tube up to the guys at Augment. David and Tom Barker kindly spent a couple of hours examining the TT. They pressed apart to find that nothing has slipped or failed prematurely. We put the shaft on engineering V blocks to check the straighteness and it's true with nondetectable round out.
The drive shaft is extremely flexible, the guys at Augment theorised that the play off the gearbox input shaft created a "corkscrew" effect into the TT which is what created the rounding out on the shaft. Once the drive shaft was pressed back into the tube the rounding out on the shaft was back to being minimal again.
The gearbox has just been rebuilt, I had a look at the failed bearing and it had a tiny bit of play in it but very difficult to tell it's a knackered part while in hand which is all down to the sheer forces at play on these perishable items..
Here is a short video with the shaft on v blocks showing how easily this flexes, not a huge amount of force merely resting your hand on it does this
