Bulletin Summary
SERVICE BULLETIN M1615: 2024 REVOLUTION MAX CHARGING SYSTEM CHANGES. PURPOSE: This bulletin informs dealers of updates made to the charging system on 2024 Revolution® Max powered vehicles. For 2024, the charging system has been updated to improve electrical output at idle and low Revolutions Per Minute (rpm). Maximum output has remained the same. The following components have been changed: Stator and Stator Screws: The stator has increased in thickness, adding more wire length and longer stator screws; Cooling Manifold: The cooling manifold needed to be machined deeper to accommodate the stator size change; Alternator Cover Screws: The screws were shortened to prevent breaking through the new cooling manifold; Rotor Assembly: The magnets were moved, re-centering them over the new stator windings. NOTE: Using any of these parts in a 2021-2023 Revolution® Max motor can result in catastrophic engine failure. NOTE: All Parts Catalogs have been updated to show correct service part numbers.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
