Autohelm ST5000 Bracket

I have an Autopilot ST5000 that works very well, but at the end of my circumnavigation of Vancouver Island last summer I noticed a small amount of play in the bracket mounting the linear drive unit to the boat. I took it apart and I can see that there's a circular retaining clip on the end of the stainless shaft that goes through the bracket.

The area I'm talking about is in the underside of the bracket where I have drawn the arrow. I've also included an overview of the bracket as installed.

There seems to be a manufactured (not worn) recess in there between the retaining clip and the casting of the bracket body where some type of washer would fit. I'm wonderiung what material of washer/spacer would be appropriate. It has to be soft enough that it is the object that wears and not the retaining clip, nor the braket body. But it will have to deal with the linear drive's up to 550 lbs of thrust, so maybe nylon is too soft? Brass?

Any suggestions? Anyone know what the OEM arrangement was?

Thanks,

Craig

It is a small plastic washer. 0.625" ID; 0.7" OD; 0.03" thick and 0.07" wide.
It does not fit down into the deeper groove but rests on the small bevel edge.

Because of the way your drive is mounted, as shown in the pic, the force is going to act on the washer and retaining ring and probably wear out a plastic washer.

If your drive was mounted in the position as shown in the posted diagram, the force would be on the swivel pin and mount body, not the washer.
