Hi there,

I have this AH 4000, the clutch lever doesn't work, and I don't know
how to take apart the drive unit "doughnut". That's the part that
attaches to the wheel. The lever that engages the pilot is not
engaging. So I figure there's a belt or something in there, not sure,
but want to see the mechanical parts to inspect, correct, repair. Any
suggestions on dismantling this piece?

thanks,

Luc
