[C38] Autohelm parts

Wed Nov 30 21:18:59 EST 2011

Hey all...

Speaking of auto helms .... Does any one have any Autohelm ST4000 parts? My wheel drive actuator went up. Well, it started slipping, and then in a blow one of the internal roller ring posts snapped off and caused one of the rollers to rattle around inside the wheel ring unit...basically disabling my steering completely. (was fun pulling the ring and the wheel off to ditch the whole thing while underway!) anyway, my control head and power supply work just fine..., and up till about 10mins ago the actuator motor did too (stupid me pulled the motor off the ring only to see the internal gears go flying...guess I can put that back together)... but my wheel drive actuator is beyond repair. so I'm looking for a wheel drive actuator ring, either with a motor, or with out.

Anyone got a box of parts laying around? Or know where I might find one? Do I really have to get a whole new system?

Oh yea btw... Found a nice canvas guy in Baltimore that just did a custom dodger for me, and is working on a complete bikini and connector too. Good price, very accommodating guy. Charm City marine Canvas. Thought I'd pass it along.

Hey Phil Gay... A big thanks to you for sending me pics of your dodger... They helped me design mine. Pic attached.

Despite what RM support said, now I find it really hard to make it work like this, but I'll give it a try. As Tom said, the wheel pilot is very easy for connections and maintenance, but despite the patented Troncalli's shock cord solution (which BTW works great most of the time!!), the wheel pilot slips when the wind is blowing hard and the weatherhelm increases...... So the linear drive should be more reliable...

If I don't make the linear drive work, I'll stick with the wheel pilot, or maybe I'll just install both autopilots, hopefully, the new 20 years old ST6000 might work and I'll have a very good back up.

If it is a Type 1, my notes indicate that it rated for up to a 22,000 lb boat, requires a 10" tiller arm, and it has a maximum of +/-35 degrees of rudder travel.   The 1L is good up to 33,000 lbs, requires a 16" tiller arm as is also limited to +/-35 degrees.

I have not yet purchased a Nexus drive unit, so I can't tell you about any firsthand results...
