I bought a used ST4000 and needed a belt. Located a new belt put it on the ST4000 and it turns easily in a clockwise direction but locks instantly in a counter clockwise direction. The lever to engage the motor is pushed fully back. If I move it into the lock position, the wheel locks in both directions. I have the older ST4000 model, black wheel.
All of the small wheels inside are in position. If the belt is not on the wheel, it turns freely in both directions.
Any ideas on how to fix? Thanks Aloisius

Sounds like your belt tension is off. Try to loosen it a little and see how it goes.You loosen #14(attached diagram) and turn screw #12 (allen wrench) to make belt looser/tighter. Tighten #14 when you are done. See attached pics & directions.

Also where are all of the 7 little wheels that support the ring still attached? They have a habit of breaking off.

Good luck...

I am replacing a few of the rubber wheels inside the black wheel. They did snap off. I am in the process of drilling a hole all of the way thru and replacing with a small SS bolt and nut.
In a manual that I have, it shows a clutch knob; in the diagram it shows a plastic cap over a locking nut. It looks like I have the cap over the nut as in the diagram. Does this cap pop off when a small screw driver is inserted? I assume I then loosen the nut, ajust the tension, and then tighten the allen screw.
Is this correct? Also my assumption on the cap over the screw? Aloisius

Yup.

Done. I drilled out all of the little wheels and replaced with a bolt. It looks like the plastic cap keeps the scre in place. I turned the screw with a 3 MM allen key and then put the cap back on. Thanks for your help. aloisius

I did the work with the ST4000 off of the wheel. It seems to be fairly stiff by itself. Once I get the wheel mounted, does it seem to stiffen the steering? Is this normal or is my system not fully functional.

I was thinking of taking each wheel off that is inside the ST4000 and sanding a little off of each to give some play between the belt and ST4000 wheel.

When the lever is in the free wheel position it should spin fairly freely. No binding for sure. Are you sure you got the right belt for the unit? I believe the ST4000 (black) has a different belt than the ST4000 MKII.

If the belt is right, try to loosen the belt some more.

I have finally gotten the wheel to spin freely. I had the tension off but when I drilled holes to put a bolt completely thru the wheel, I drilled it slightly off-center. I had to have the hole welded, then redrilled the hole. Alos would have been a terrible mistake to have sanded a wheel!!!
Now the wheel is on but a pole is slightly in the way of the electrically connection when I attach to the helm. Off hte two location plugs, only one can be used. Today I solve that problem.
