Description
Genuine Harley-Davidson cylindrical roller bearing (equivalent to RNU205E) that fits in the inner primary housing and supports the transmission mainshaft. A worn bearing causes primary noise and mainshaft play, so replace it during any primary or transmission rebuild.
Sold individually. Retaining rings are available separately.
Fitment: 1985-2006 Big Twin models (Evolution and Twin Cam with the late-style inner primary). Confirm fitment with our parts team.
