On my 1966(?) Cub cadet 123 I am swapping out my axle for an axle with beefier spindles (putting a front loader on my 123). I lifted up the tractor, and the axle pivot bolt looks more like a pin. It definitely is not a bolt. And the ends of the pin are flush with frame pivot brace. I cannot see for the life of me how to remove it. It does not budge trying to drive it a little from front to back and I am afraid to try to press it out rear-to-front using the oil pan as a brace.

Is my parts diagram lying (it shows a shouldered bolt)? Or is this an owner mod? Any idea how to remove it?

Its dark in that are of the shop, the pin area is full of grease and a old sloppy re-paint job so it is hard to see. But I will try to get a picture.

Thanks in advance!
