Autohelm 4000 drive problem
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 |

Go to a chandler and buy the replacement belt.
This comes with instructions. Yes they do fail after a few years. Alec "luc" wrote in message oups.com...

Any suggestions on dismantling this piece? thanks, Luc The front part just snaps over the rollers which are attached to the back section. You just pry it off. If the clutch is not engaging it could be the belt or the clutch mechanism. There are split pins in the system and sometimes these shear off. Now the clutch shaft rotates but doesn't drive the eccentric wheel that tensions the belt. Raymarine sells a rebuild kit for the clutch, something like $75US. Just call an authorized repair centre as listed on the Raymarine website. |
