First the failures: I made a puller out of square tubing with a keyway slot consisting of a 1/2" hole and a 3/4" hole. I filed out the material between with the resulting opening looking like a key opening for a skeleton key. Two 1/2"-20 bolts were threaded though the ends of the tubing to press against the axle flange. This worked on the right side pin, but tore the head most of the way off the left side pin. Next the left side pin was drilled and tapped 3/8"-16. Ran a 6" piece of hardware store threaded rod through a 3/4" deep well socket. Added a few washers, then a long coupling nut. The cheap theaded rod broke, but I was able to get the broken piece out of the pin. Bought some grade 8 threaded rod. It held out a long time, but eventually failed and didn't budge the pin. Tried the suggested method of loosening all the axle flange bolts and jacking up the tractor by the axle. Since the pin was not stuck in the outer hole, this did nothing. (The pin would have to be stuck in both the outer and inner holes for this to accomplish anything!). What finally worked was to use a long piece of grade 8 threaded rod, through the deep well socket with a washer and nut tightened to near the breaking point. On the end of the long threaed rod, I placed an old 3 lb. hammer head, some large washers and a nut. Repeated slide-hammering with occasional tightening of the nut on the socket got it out, but not without a helluva fight. My hand is tremoring as I write this!
