Hi again Newton, My reply was , as usual, more simple minded than what I meant. True, the contact *area* is the same up to about 20 degrees off straight, but the fore and aft *position* of the contact changes as the pin is turned. That means that the "adjustment" is more sensitive with worn bushings than with new ones. You have to turn the pin further in new, straight sided, bushings to take up the same slack. It would make no real functional difference in new bushings if the pins are exactly straight or not, so you're right there (though it seems kind of sloppy, and I know you wouldn't do it unless threatened), but if there is any wear in the bushing, it makes a big difference. With worn bushings, the contact area gets very small very quickly with a few degrees of turn. That's what I meant by turning pins as a means to milk a little more mileage out of a set of bushings. Incidently, that 20 degrees (or so) turn only amounts to about 0.010" against parallel sides. That kind of surprised me when I measured it just now. If I screwed up my explanation of what I think I meant again, I've got a drawing I can attach that makes it a little easier to visualize. Sorry about the incoherence. Ron
