But the more I think about it, the more I've come to the conclusion that you are playing with fire if using this recommended skf 22030 seal. This is NOT a direct cross-reference replacement. Not sure about the National seal, but I bet it's similar to the SKF in that it is a single-lip and only 8mm wide.
On the original "wear sleeve" (where this seal rides), there are TWO (2) lines worn into it from where the original John Deere (pt# JDCH14691) 12mm seal rode on it. Yanmar/John Deere used a double-lip seal for a reason, and while the thinner 8mm/single-lip seal might have lasted for a while, there is no way it would have lasted as long....
Moral to the story is sometimes you have to "suck it up" and pay John Deeres extortionate prices as they are the only game in town. I've looked and cannot find the AE7450F at a lesser price than JD.
