can anyone tell me how to remove rear nut to change compression/clutch springs

[tomsnott]

I have a 2008 people 150 and decided to get a new variator, rooler weights and springs. I was able to change the roller weights
but I can't get the rear nut off to get to the clutch assemblyoff to chabge the springs. I've tried jamming the rear brake to hold but it slips.
Can anyone tell me how to remove it?
Thanks,
Tom

That tool, and an impact driver will make short work of it.

Hey tomsnott,

Were you replacing worn out parts or going for better performance with these changes?  Or both?  How did it turn out?

Thanks.

Mike
