1989 to 1990 clutch upgrade... and clutch hub nut.. what does it locate on?

[1340evo]

Well, my new clutch arrived today and it looks like new!... must be off a very low miles bike I guess... very pleased with it

But just looking how it will go on the shaft (shaft not arrived yet)... and what the nut locks up against (didn't come with the nut)... Is it the small inside diameter... or the big area that says 'out' on it?... If its the latter, this bit is dished so won't seat very well... so I'm thinking it's the inner bit... but not right big if it is?.. does anyone know?

Also... what stops the oil going down the gearbox main shaft one way or the other?... cant see any seal in there??..

Is it the small inside diameter...

Yes  , buy a new nut

Yup.. It's the inner bit.. .do you know thw torque for this?.. is it 60 LBF like the taper one... only a thin area to seat on and not right tick?...

I will get the nut but just trying to work it out...

however... I could turn the old one down to fit
