The curve spring washer is just like Don describes it, a round washer of springy steel with a curve in one plain (thing of a washer bent around the outside of a rod. It exerts a relatively light thrust. The Belleville Spring is more heavy duty, formed in sort of a cone shape and can be stacked together for more thrust.
Small Parts, Inc is a good source for both of these http://www.smallparts.com they also have a great catalog for the asking and a lot of 304 and 314 Stainless hardware that might interest a boatowner.

| Don,
I may be wrong but I think you are referring to a washer that is called a Bellview washer.

My M-18 had a bungee cord to hold the throttle when I got her. I tried to tighten the friction screw under the compass, but it was tight as it would go. The fix. On the front starboard side of the engine there is a throttle bell crank. It is located on the forward end on the high pressure fuel pump. It has a screw with a smooth shank and threads on the end. The nut does not compress the bell crank so it can rotate. I removed the nut and added a spring washer over the smooth part. The spring washer gives it a little friction, but still allows smooth movement. A spring washer is very thin spring steel that has a slight curve. They are very common on aircraft, but I don't know if a hardware store would carry them. You could probably use a split washer and maybe some thin flat washers to do the same thing. It may take a few combinations to get it right. It has been several yea! rs since I did this and it works great. The throttle is easy to move and stay put.

Presently, it always drops to about 1200 RPM unless I hold the throttle. I looked in the Edson manual which suggested that there is a tension adjustment for the throttle. I inspected the innards of the Edson dual control assembly this afternoon and found NO tension adjustment. There is a self tapping screw holding the nylon bushing in place but no tension adjustment. Has anyone else had this problem and have a fix? John C27 #5956 Austin, TX |
