I own a 1956 WD45 gas that has a trans. leak that is steadily going back. From what I can tell, I think it's from the first PTO shaft seal; can't really tell. Anyone got any advice or tips for repair/replace? Can I just delete the PTO in general from the trans. or hydro. pump?

Help needed, please.

Get some towels and break clean and clean everything up and find where the leak is coming from. You can drop off the bottom PO gearbox and delete if you want. It's not hard to put a couple gaskets and a seal into it and fix the leaks.

Ok thank you. But I have bigger fish to fry first; my entire left rim is basically non-existent.

How hard are seals to find for that spot if I had time to replace?

I don't remember where I got mine 10 years ago. You'd need the gasket for that 2 bolt flange and hte seal. It's also likely your leaking old between the PTO box and the upper torque tube. Check that and It's not hard to do that gasket at the same time.

I think AGCO has them, Steiner, DJ's tractor and probably other here on the site.
They are very available
