## NHTSA's summary

SERVICE BULLETIN M1571: REVOLUTION MAX CLUTCH PART AND SERVICE PROCEDURE CHANGE. PURPOSE: 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. Online Service Manuals located in Service Information Portal \(SIP\) and future printed copies will reflect this information. See https://serviceinfo.harley\-davidson.com for the latest electronic version of the service manual.
