I've been working on the restoration of my 1972 R/75. Tonight I was putting the left side bearing back in after it had been cleaned and greased. I ended up with a gap next to the oil seal. I don't remember there being a gap like this when I removed the back wheel. I've pulled the bearing back out and put it back in several times. Everything seems to be lined up correctly. Any insight on where I might have gone wrong would be appreciated.
