I am amazed at the obvious intelligence, of the old engineers, that designed the older AC tractors, and equipment. The way they were able to make things work, with linkages, and metal straps. At the same time WHY would they design the brake pins, on the small Allis's, to fit in blind holes, with no provisions to punch them out, when you needed to replace the worn brakes. At the very least, they could have provided heads on the pins, so they could have been spun in the holes, to looseon them up. I lose a boxend wrench, each time I weld a wrench to them, to use as a handle, and I don't keep cheap wrenches. I know they have all died off, but I still would like to slap the guy, upside the head. The old C that I brought home yesterday has the right wheel frozen, and wont break loose, and I am reasonably sure, that the brake is frozen to the drum. It is now soaking in an ATF and diesel mixture. WHY do I continue to buy these things? Not real smart!
