I just changed the rollers on my 2009 Silver Wing with 30k miles on it and cleaned everything up. I put the stock rollers in. I checked the drive face boss for wear and it's still within tollerences. I'm ready to put it back together and am wondering if I need to use grease on the boss? The service manual makes no mention of it. I'm thinking white lithium or Molly grease. Just a light coating. What do you guys think?
