Mountfield BBC Clutch Removal

[MGH]

I've damaged the Blade Clutch on my Mountfoeld M3, MPR 10009 (200

model).

I'm a fairly good amateur mechanic, but I CANNOT get the B****** thin off!

Does anybody know the trick please??

The part in question is no 136 on the diagram on this URL.

thanks,

Mik
