Stripped gearbox in the frame last few days as although I was certain it probably had an upgraded layshaft brg I realised I was perhaps living on borrowed time as I have had it 3 years. The main reason though rather than the Russian roulette I was playing was that it has some clutch basket wobble and a lot of slack in the drive. It all looks pretty good in there, there is play in the sleeve gear bushes but the gears look fine and it has a FAG NJ203E. Here's the problem (note inner chaincase still on until I make an alternator puller):
Basically there was no sleeve gear oil brg seal. Should there be a boss to accept that where all the crowshit weld is? There doesn't appear to be any crack between the main and layshaft brg housings. What would you do? Live without the seal? There was a fair bit of oil in the primary (it has a belt drive and I changed the crank oil seal behind the aternator pulley a few thousand miles ago, also has a good breather)? Not sure where that's from as it fly more off the back of the final drive sprocket wouldnt it?
This is the original gbox shell which I would like to keep. Help.
