I wonder, if since it's discontinued, and no longer available from Raymarine. If these new replacement belts aren't exactly to the original specs. Hence, a little tight.

Page 12 strangely won't load for me, but I'm pretty sure I have it in the loosest position. With the wheel/cam in all the way, there should be the least amount of tension on the belt. Also, with how easily the ring and plate FINALLY went together, I'm pretty sure I have it right.

Heat it and stretch it.

Some of the belts sold on ebay and elsewhere are very stiff. They are the right size, but so stiff that they cause problems.

The adjusting cam should rotate about 300 degrees. It does not go full circle.

Put the wheel completely back together. Looking at the BACK of the wheel, adjust the cam full counterclockwise. If you hold the clutch lever in about half way, you will see the lever move as you rotate the cam adjuster.

If you need a good belt, send a PM.

And the answer is much more simple than we all thought. Silicone spray! And instantly, I have 1 finger steering again.

That is great............but I don't get it. Tight is tight. Spray doesn't loosen an over tight belt.

But hey..............if it works it works.

Unless it wasn't REALLY tight, but mainly just friction that made it seem extra tight.

Re: Raymarine ST4000+ Belt Tension

problem soled.....for real
I have the older black version. I was having the same problem.
I bought the d169 at5/750mm belt from poly belt. I thought I bought the wrong belt; I called ray marine, this is the belt they recommend. I put silicone spray, adjusted the cam with no luck.
There are two pieces to the hub. The part with the motor attached, and the other. on the other piece where the belt grabs when unit is engaged, I took some 40 grit sand paper: and sanded around it. I'd sand a bit then snap it together to test it. it wasn't a whole lot I had to sand. when I finally sanded enough so the hub would slide easily while disengaged, I used 60,100,120,220 to smooth the plastic back out. It works like a charm now. If the belt stretches over time there wont be any problem because there is room for full adjustment, because I had the tensioner in it's loosest position.
good luck and happy sailing. :thumb
