I've only had my Super-A about a week, and it's my first tractor, so I might be talking through my hat, but I'm in the middle of replacing the same seal on my pulley shaft.
I backed out those three bolts, and the cover didn't want to budge, but it had a gasket behind it that was stuck pretty fast. One medium pop with a rubber hammer broke her loose.
Again, because it's my first OLD piece of machinery, I wasn't sure what I was looking at, in regards to the seal in that cover plate. It had the rubber-with-spring I'm familiar with from more modern auto applications, but it also had a metal separator, and then a felt(?) ring, all encased in metal. At first glance, I thought I had the bearing sandwiched between separate retaining caps. But no, it was one humongous seal, fully 5/8 inch thick. Never seen anything like it. Local guy pressed it out for me, but now that I know, I could have done it with a drift and a hammer and a light touch.
What a hoot. The new seal is half the thickness, and I'm thinking, as I heard advised, of putting in two.
Weird, too, on my Super-A, the seal sits on a bushing/spacer thing, and not on the shaft itself! Don't see how it can completely seal, without a little silicone or such under that bushing/spacer, but I don't want to booger anything up. I can live with an occasional drip. The open-spigot I had BEFORE the seal replacement, I couldn't live with!

So there's my two cents. If the M and Super-A aren't comparable.....never mind!

But I'm going to keep that seal. It's as old as I am.
