For pivot pins remove grease zeros and bolts. Next screw a longer bolt in and drive the pins out. To remove the bushings I weld around the bushing to shrink them. Tilt pins are easy remove the bolts pound out the pins and drive the bushings out. Before installing bushings throw them in the freezer overnight and they will shrink making easier installIt can be a pain to get them out, but when out, you just knock the bushings out and install new ones and new pins.
