But looking through my box and notes I find the FW side seal that you came up with is wrong, the Dichtomatic 056081TC is only for a .500 shaft. I recently came across a bag full of NOS 1986 seals and they are for a bigger shaft. The SKF 5523 is the correct seal for the fw side.
So let me say the seals for a 360-451 are
SKF 5523 FW side and SKF 7414 for the PTO side.
Randy these are the seals I think I originally came up with and had in that list that I gave you to go over. The Dichtomatic 07111TB appears to be correct for the PTO, I don't know, never tried one.
I do at this point know that the Dichtomatic 056081TC that you came up with is not correct for the FW side. It's maybe my fault I didn't catch that sooner. I actually bought a couple of those and just threw them in my seal box, but again I didn't have a NOS seal here to compare to and wasn't tearing them back out of my saw that already had the SKF seals in it.
I think you got caught up in trying to find the "improved" seals with the double lip on them, which is fine but I do not go out of my way to find double lip seals to replace a OEM single lip seal.
The outer lips most the time are just a dust seal and when on the FW side on like a 361 that used a closed point box on top of that seal, I find a double lip seal to be of little advantage.
If I remember right the original PTO side seal was single lip as well and those have lasted for many years
