Thanks for the suggestions on dealing with the implement shaft. I am a believer in the magic powers of both Kroil and PB Blaster, but I am not always a patient man. When it comes to cautiously heating, tapping, apply oil and repeating the process until the part is free again, I usually get carried away with the tapping part. So knowing my limits, I took the whole frame to work and used the hydraulic press and some very good blocking to support everything while I applied some pressure on the shaft. A little heat and 11 TONS of pressure and it finally came free. After cleaning all the pieces, they slip fit within each other again. Given that there already were two holes in the bushing section of the J arm, I tapped one to 1/8" NPT and installed a grease fitting. It won't seize again!
Onward to sanding the frame and some high build primer! I need to see RED!
