In days of old, many a manufacturer of automobiles, horseless carriages if you will, used this same system, however, they used a tapered pin, with a nut on one end, that pulled it thru the eye in the axle, and kept the pingpins not only tight, but kept them from turning, which is all the allens can do, keep them from turning, they are known as a push fit clearance, and unless they get really wiggely, it has the advantage of allowing you to remove them with little effort, not like the cars of old, that when it came time to replace king pin bushings, you might just as well remove the axle and replace it also, the marriage was forever. If it gets too bad, you could remove them, and knurl them where they rest in the eye, but that would mean doing it before they were hardened, assuming they are hardened to begin with. BTW, if you are thinking about the tapered pin option, Snapper mowers have them in their rear axle, about a 5/16 hole I believe. Bob
