Title: Autohelm ST4000 Autopilot clutch failure
Post by: Hank Busey on July 20, 2008, 09:01:09 PM
The Autohelm 4000 clutch has failed on "Bitterroot", and I am told by the dealer that the clutch replacement  kit is no longer available, and that the unit cannot be repaired.  Since the electronics are good, I would be delighted to hear from anyone who has a working wheel unit that they would be willing to sell.  Thanks.

I've got a first generation 4000.  The control pad is fried, the wheel unit has been rebuilt a couple times, the clutch has some "mcgiver" mods to make it work.  It squeaks alot but might have a year or two left in it.  Unfortunately I won't be back to the boat for a couple of weeks.

Ken, that sounds great.  I would be happy to pay postage plus whatever you feel the unit is worth.

I experienced the same failure on my autohelm 4000. I had found the article on the C36 list that Stu referenced above and repaired my unit the same way.  While I was at it, I followed the same procedure on all of the rollers to prevent the same failure from happening on any of them in the future.  One suggestions is to use acorn nuts on the ends of the bolts where they are exposed on the forward side of the unit.
