I was finishing up a John Deere 445 in the shop, and suddenly the fuel injector nozzle sprung a leak. I assumed a failed o-ring (part number M122644). No John Deere dealer around has one in stock, and I need this o-ring ASAP, as in TODAY. I removed the nozzle to inspect the o-ring, and it looked OK. So I lubed it, and put it back in the throttle body, and it's not leaking at all now. But I'm afraid to trust it. This is a long shot, but does anyone know offhand of a different OEM o-ring that matches the specs of this o-ring?
