Hi Jim,
You are on the right track. Once you pull the screw out you will see how it works. You put the spring washer between the flat bar piece and the bushing. The screw has a slightly larger shank, so when the nut is tightened, the bar does not bind. If one spring washer does not give enough tension, then add a thin flat washer to the spring washer. Let me know how it goes.

My 1986 Catalina Tall Rig has this same problem. I have just returned from examining the mechanism on the boat. Although I can see clearly all of the parts, after identifying the cable coming from the Edson pedestal! , I do not know the correct names of the subsequent parts. Therefore, it is not entirely clear to me where to put the spring washer or Bellview washer that I will buy. Is there a picture somewhere on the net?It appears to me that the washer would be placed where a 2 1/2 inch piece of flat metal (that is attached on one end to the cable) pivots in the middle. The point of pivot has a 1/4--1/2 inch thick washer (bushing?) between the pivoting metal strip and the body of the engine. Would I put the spring washer between the strip and the current washer-bushing? Does this make sense?Jim Barham----- Origi! nal Message -----From: [EMAIL PROTECTED]Sent: Tuesday, January 03, 2006 1:52 PMSubject: Re: catalina27-talk: Universal Diesel throttle tension
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. (not sure of the spelling)

Yup. 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, b! ut 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.

My 1985 C-27's, with factory Edson wheel steering, Universal diesel
throttle does not have enough tension to maintain RPM. 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?
