Clutch problems Tm-racing 250 95'

Hello first of all thanks for welcoming me at this great site. I have a small problem what I can't figure out on the moment. Last week I was driving and the nut on the crankshaft came loose. I fixed it with a little loctite and tightened up the nut again.

My big failure was that I damaged the inner hub from the clutch, 2 of the pilons (where the springs fall over) broke of when I tried to loosen up the main nut in the clutch not using the proper tools...

I saw that the clutches of TM from 95 till 2018 are exchangeable they are al the same model.
So I ordered a 2010 straight from ebay and fixed it again. Now my problem is that I lost the ability to shift it feels like a scooter pulling up with variomatic, it's revving like hell and after 200mtrs my clutch smelled burned and gone completly.

My question is could it be that my inner hub is wrong the only difference I saw with the new and old one is that they drilled a lot more of aligned holes into the inner hub for oil i think?? The clutch feels like slipping or dragging i am new at this so help would be really great.

PS I used the springs that came with the 2010 clutch could this be false aswell? So there's maybe no grip when the clutch comes up??

The specs of the bike are:
