I thought Id post sum pics of my new hitch pins, Not quite done yet. Still need to mill a square on the threaded end of the lower mount pin, Just like on the threaded end of a shock absorber to hold while you torque the nut down. Also the upper pins need the hole threw the brass bushing for the roll pin.
The Idea is to swap out the bushings instead of wearing the pin receivers. Especially the top hitch point, Thats where your your not just wearing out the pin hole on the mule, But your also wearing the pin mount holes in your tractor, these brass bushings bridge all three holes.
The brass should absorb the abuse instead of the recievers, and the pin, I dunno how long before they wear out? or if they will mushroom to the point that the pin wont slide out, (disengage). At that point bushings would need changed. Depending on what happens, I might use a harder spec of either brass or maybe even a oil enpregnated bronze, a soft aluminum, or possibably even a nylon, a composite bushing is also on the list of I wonder if- ???s
The lower hitch reciever pin is adjustable, using different sized bushings. Depending on how bad the mule is claped out. Standard 5/8, plus a 11/16 or 3/4 bushings can be used. I used a 1/4 button head socket bolt to retain the bushing. Pics of these are also in my album below. (blue button)
Iam hoping to stop the pins gettin smaller, And the holes gettin bigger issue, will see.
