| Re: Inner Primary Bearing Failure
Roy,
The inner primary roller bearing 9231 is pressed into the inner primary case and the inner race 34091-06 is pressed onto the input shaft of the gearbox.
I replaced this bearing only and the lip seal. The clutch hub bearing was fine.
I did replace the sealing bolts but might not bother next time. Cheap enough though. You have to remove the inner primary case to press out the bearing race.
The locking tool can be made from a 7" long piece of bar. You are not supposed to use the older type of stepped lock. You can borrow my locking tool.
When you come to pressing the bearing in, put it in the freezer for a while and put the case in the oven. There might be a reason why you shouldn't do this so chime in if anyone knows better. I did it this way and it seemed fine.
I can't remember the nut sizes right now but the clutch is the same as always but the comp nut is smaller than previous.
You will need the gasket between the crankcase and inner primary case, plus a few other bits and if you want to be really posh, the primary gasket as well.
I'll send you a parts list when I get back home.
Check stock before you pull it apart though.
It's worth checking your rotor as per jaguartvr's post. The bolts come loose and destroy the stator. I did as Phil recommended and put green loctite 290 down the threads.
