    High Miles BBSHD Maintenance


    My BBSHD is starting to have two symptoms after 10,000 miles.

    1) Pedalling at mid to high power feels notchy. It sounds and feels like a bearing issue.

    2) The BBSHD isn't engaging at low power (PAS 1,2,3), but it sounds like it is skipping. Adding more PAS, or throttle forces the clutch to engage.

    This BBSHD has never been opened, and either problem might be solved with cleaning and regreasing. What would you do, and what parts could be needed?

    I would go ahead and buy the clutch-bearing and plastic primary gear. Get a tube of the right kind of grease, so...you can do the refurbish quickly.

      I can't find the nylon gear on LUNA's site. :( Must be out of stock

      There is a thrust bearing but I am not see a clutch-bearing.
