I bielieve your right...Never had to do mine since greased it yearly and replaced as a assembly at 8000mi. It's pressed on shaft and also into the aluminum frame member so I believe you have to drive it out from chaincase side and then press it off shaft.
For now I did clean and grease, seemed good. Definatly a yearly think to do for sure.
