Raymarine ST4000+ autopilot service & replacement...

[@SailingBritaly]

Nicely repaired and a very useful videos for other people with the same problem. Good stuff! Chris

[@dsgUTube1]

Thank you for posting -- my unit has at times been squeaking and running a warmish motor -- suspect some binding inside -- and the chatter between the plates resembles your 'before' condition. I have been apprehensive about dismantling, but your video addresses that concern. And most of all, thank you for the source for the parts!

Where did you order the 3rd printed replacement kit? Thanks

[@stephankiss2328]

Hello. Thanks for thé vidéo. How did you this 3d print wheels?

[@ronankenneally9713]

Thanks moonquest . Do you know if there is some specific way the two covers press together. I just did the i3DGear marine replacement , but the unit still does not press together firmly . I also notice you did not remove the attachments to the steering wheel . Is the placement of these important ? Thanks Ronan Kenneally , Cork

[@6r4metroman]

Hi Ronan, I sold the boat not long after making this video, not sure if the 'fit' needs to be firm! I did not need to remove the base plate as you can see from the video. The base plate only fits the wheel one way depending on the number of spokes in the wheel, there are pre-drilled holes...

@@6r4metroman thanks metroman- still battling with mine ! Your video helped a lot so far .👍

[@modfountain4840]

Very helpful.

[@leeg6826]

I'm sure I have the same problem because the 2 plates are not close together anymore. Where did you get the "guide wheels"/

[@i3dgearmarine908]

The 3D printed roller wheels are available from i3DGear Marine at: www.i3dgear.com/online-store/Roller-Wheel-Autohelm-4000-ST4000-Wheel-Pilot-Set-of-7-A18058-p92001167 . Our company carries a full line of 3D printed replacement parts for the Autohelm / Raymarine wheel pilots. They come with complete repair instructions. There is also a repair kit for fixing one of the roller posts, which often break off.

[@StevenMasur]

I love this video. The one thing you gloss over is the thing one really needs, which is the little wheel thingies inside the unit, which wear out, and are how the unit holds itself together. Where can I get these? You said you had these made with a 3D printer? How do I get ahold of THAT guy?

Hi, details are in the comments but here you go... The 3D printed roller wheels are available from i3DGear Marine at: www.i3dgear.com/online-store/Roller-Wheel-Autohelm-4000-ST4000-Wheel-Pilot-Set-of-7-A18058-p92001167 .

Thanks.

[@MrBrMrB]

I've also one of these autopilots. After it has been operational for a while, the drive lever is forced to be deactivated / lifted up. Do you have any idea about the possible reason of this malfunction? Thank you in advance for your kind assistance

[@6r4metroman]

Hi Bora, I don't use that unit anymore but I'm sure there is an acentric screw that can increase the pressure on the belt to stop it jumping off. Undo the locking grub & turn the shaft to increase the tension...

[@MrBrMrB]

Hi @@6r4metroman, do you mean I should increase the tension on the adjustment locking nut that lies just behind the protection cap?

[@i3dgearmarine908]

Another common cause for this problem is the pins in the lever's eccentric cam shearing - not allowing the lever to actuate the cam properly. It is very difficult to fix the sheared pins, but i3DGear sells a 3D printed Stainless Steel replacement (all one piece - no pins to shear). You can find it at: www.i3dgear.com/online-store/Drive-Eccentric-Assemby-Autohelm-4000-ST4000-Wheelpilot-p98852261

[@MrBrMrB]

@@i3dgearmarine908 Thank You for Your reply. So far I've resolved the problem by loosing the adjustment cam so it doesn't make more than necessary pressure on the belt :) By the way, when I was repairing the autopilot, I've also checked the rollers You did supply in 2018. They are in perfect condition :)

[@i3dgearmarine908]

@@MrBrMrB That's good news. We haven't had any complaints in 3 years of supplying the rollers. Glad you got your belt problem resolved.

[@SmodoStein]

How did you open the ring ? Are there any screws or is it just clicked to together ?

[@philgladwin6863]

Hi, its just pulls apart, clips together...

Where did you purchase the replacement black discs

From the US, are you in the UK?

[@BMF123321]

How often you have to do this?

[@6r4metroman]

It was almost 20 years old!!

[@axleaccor8459]

I am actually in the US on the east coast near Baltimore. I believe these can be found on eBay, but I am interested any sources you may have.

[@sailingmoonquest4963]

I ended up replacing the whole unit with a mk2. Here are the contact details. www.i3dgear.com/

[@snakeplisken4278]

is mk2 made by auto helm?

[@sailingmoonquest4963]

Yes its a lot stronger...

[@TaylanYalniz]

@@sailingmoonquest4963 when you replaced the whole unit does it mean the control computer and the motor, too?

[@6r4metroman]

@@TaylanYalniz The mk2 came with a new motor, did not need to replace the head you, just plugged it in as normal...
