Raymarine St 4000 Wheel Drive

my wheel pilot on my raymarine very loose moving up and down with no resistance. I assume the locking mechanism on the inside of the wheel has broken. Anyone deal with this before? I've called Raymarine and they have said that it should be sent in. In the interest of time and money I would like to effect a repair myself.

    I have the same problem with my st 4000 series, and I have found that the roll pins are sheared in the ingage shaft. I am trying to find these roll pins, To make this repair it will require the removal of the handle by removing this roll pin, then install the roller cam with two new pins, then install the cam and shaft, then reinstall the handle. I would like to find a parts list for this unit. Wayne on the LOST TEXAN

I had face with similar trouble

I went to RayMarine Web site and got an ecopy of the manual. Inside there is a 3D Blow up of the inner workings of the Auto Pilot. There are a couple of shear pins inside on the clutch lever. It shows you how to disassemble the auto and replace the shear pins. Total cost was $0.20. It works GREAT now. No more problems. I was also was able to give the inner working a good cleaning and lube. I have a soft copy of the manual if you need it

Can the 12093 operate without something else. just need something to hold a preset direction ..dont need to know direction, just hold course

The wheeldrive is only a mechanical actuator ,it will not pilot ,it will only drive the wheel ,you need a control unit ,several 4000 or 3000 units are suitable ,
some have an internal compass others need an external compass

RayMarine wheel 4000

You would need to supply more info to pin point problem. 1) Do you have hydaulic steering?If so do you have a rudder feed back sensor. 2) Is this a new install or did the pilot work properly before 3) Do you have a smart pilot course computer in the system or is the wheel drive run straight from the head unit. 4)What was the deveation reading on your auto pilot compass when it was swang. 5)Was the pilot comissioned by a qualified person. I know there is a lot of questions here but there could be many things that are causing the S.Once the above questions are resolved I should be able to narrow it down to one or two things.
