I've got a '97 Sportster (bought used) and just replaced the primary cover gasket. I bought a shifter shaft oil seal (rubber) figuring I'd swap that out while I had the cover off but, I couldn't figure out how to get it out. Parts book shows a bushing and the oil seal, I figured the seal was pressed into a groove in the bushing because there was brass on either side of the seal, but I wasn't sure so I didn't mess with it. Out of curiosity I went to the dealer and they pulled a bushing off the shelf. Short, thin and no groove for a seal. We looked at a later model Sporty and you could see the seal at the outside of the primary cover. Did this design change or did someone bastardize my shifter shaft oil seal and bushing?
