I'm having exactly the opposite trouble? Can't get the nut undone, period!
Local guy managed, but says final drive bearing / dynamo just as tight - HE's unable to get those out (mentioned "specialist tools", I'm taking my thinking hammer tomorrow), recommending reconditioned motor.
This all for the 100,000 (trouble free) Km service, only trouble being the motor'll set me back about £700, plus £300 tax!
Wondering if there might be any tips / tricks to aid removal?
Thanks in advance
