Go to a chandler and buy the replacement belt.

This comes with instructions.

Yes they do fail after a few years.

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

How about reading the manual that you can download fromwww.raymarine.com?

read the manual, no information on dismantling the drive unit.
