Loose Edson Steering Pully Reprised

On January 5 I posted a question about how best to fix a loose horizontal steering pully on the Edson steering system for my 79 H33. . (I called it steering pully, some respondants called it quadrant and the Edson catalog I now know calls it a Radial Drive Wheel.) This wheel was so loose on the rudder shaft that it was kept from sliding down the shaft only through the supporting action of the steering cables which in turn had worn the softer aluminum pully to a knife edge in the impinging areas. Steering was still maintained but lots of slop since all the contact was being taken by the connecting bronze key which in turn was being forged ever smaller by the repetitive shearing. Recommendations received included replacement (a sound but expensive option), JB Weld, loctite, and shimming. I took it apart planning to shim since Sam Lust's recommendation of beer can shim stock sounded sound and economical. The Rainbow Chaser site has a good discussion of the difficulties of removing the drive wheel since the galvanic corrosion between stainless bolt and aluminum wheel is an evil combination. Gene's experience related there was pretty much exactly what I ran into also. Anybody planning on taking that wheel off should check out his site for sure. I ended up simply machining both wheel halves probably 1/16" on a wood working jointer. Oh well my knives needed sharpening anyway and it fixed the wheel probably better than new for it was probably loose from the time of manufacture. I would recommend anyone with Edson of this vintage to check this wheel for play for if there is any at all, it will only get worse as the key is worked on.

Neat solution!

Simple is better. I'm sure the sound of that jointer on the aluminum was impressive! I've found that good penetrating oil and patience work on those corrosion problems. For the record, I mixed up my own penetrating oil out of equal parts old diesel fuel, old 2-stroke gas mix, Marvel Mystery oil, engine oil (doesn't have to be old) and paint thinner. So far it has been effective in un-sticking the rusted piston in a friend's Atomic 4, and several corroded fasteners. And it is cheap. Cheap is just about as good as simple.
