Re: Stus-List Raymarine ST4000 autopilot problem

Hey Dennis - Do you remember the Gates part number? I've swapped belts twice now, and the only one that has worked for me has been the Polybelt. I put an Ametric belt on with the same exact specs and it didn't work well. I made it work for a year, but it was a worry. Wal Dennis C. wrote:

Re: Stus-List Raymarine ST4000 autopilot problem

It may be a different problem, but the cam is attached to "flipper" post by two 1/32 inch, I think, roller pins. I had this problem and these were sheered off allowing cam to go too far and lock the pilot on. Purchased replacement pins at a local Fastenal store. Bill Walker CnC 36 Pentwater,

Re: Stus-List Raymarine ST4000 autopilot problem

Joe, Mine did that and the local Raymarine dealer had me tighten the belt. I had to fiddle with it for a while but I'm not using the bungee cord anymore. Good luck, Mike Virginia Lee, C&C 36 CB Virginia Beach, VA Sent from my iPad > On Oct 3, 2013, at 9:05, "Joe Della Barba" wrote: > >

Mine has an issue where it randomly releases :( I "fixed" it with a bungee, but does anyone know what part is causing this? I have fixed the opposite issue where it won't work because the drive pin shears about 5 times from buying the thing in 1989 to now. BTW - do not EVER let all the plastic g

Re: Stus-List Raymarine ST4000 autopilot problem

Hi David,I really misread your original problem.  I thought the autopilot wouldn't engage, but your problem was it wouldn't release.  That's a neat piece of seamanship to drop sails and anchor before the race, remove the wheel drive and restart the race.It must be an older model autohelm if it won'

Re: Stus-List Raymarine ST4000 autopilot problem

I had the reverse problem, my clutch wouldn't stay engaged. The clutch mechanism is very simple. Once you take it apart I'm sure you'll be able to figure it out. You can use a flathead screwdriver like another lister mentioned, I just ripped the two sides apart using brute force... a finesse type o

Re: Stus-List Raymarine ST4000 autopilot problem

It may simply be a loose belt?  There is a tensioner for that if it is a 4000 Plus.Another bandaid fix is to shockcord the clutch lever so it can't release on you.  Check the mechanicals first.  RayMarine recommends washing it out with fresh water periodically.   Good luck.

Re: Stus-List Raymarine ST4000 autopilot problem

To open the wheel unit, put a large flat screwdriver or pry between the two circular segments and pry them apart. This will expose the drive belt, idler pulleys and the tensioning clutch lever. The problem you are having is mechanical. Rich Knowles Indigo. LF38 Halifax On Sep 29, 2013, at 18:

Re: Stus-List Raymarine ST4000 autopilot problem

I had exactly the same problem. Changed out the wheel unit with a new-to-me (but better condition) unit. Thought that solved the problem. Did it again! I found that if I switch off the power to the controller I do not have the problem. I know only switch on the auto helm power when I am using it
