PURPOSE: Revision. Updated Motorcycles Affected. This bulletin informs dealers that Harley-Davidson Revolution®Max clutches will be serviced by a clutch disc kit and not with individual plates. A new clutch disc service kit (Part No. 37000383) will be provided for making clutch repairs on all Revolution® Max powered vehicles moving forward. The procedure of replacing individual discs is no longer recommended. If one steel or fiber plate requires replacement, a clutch disc kit will need to be installed.
