John,

Where on earth did that bizarre-looking thing come from?  It appears to be some sort of spacer that somebody installed for some reason? For sure it doesn't belong there (look at the exploded parts diagram). I think you found and fixed your problem!

When I asked the guy at the shop where this washer-thing goes, he said he'd never seen one and didn't know but it appeared to him that the "up" surface shown in the photo goes against the seal between the bearing and the seal, so that's what I did and got the scrape.
