Bulletin Summary
SERVICE BULLETIN M1492: 2017 - 2019 TOURING - MILWAUKEE EIGHT - INNER PRIMARY VENT. PURPOSE: REVISION. Harley-Davidson has learned that a small percentage of dealers and customers are finding low transmission oil levels and high primary oil levels during normal maintenance intervals. This could indicate that oil is transferring from the transmission case to the primary housing through the transmission mainshaft. A inner primary vent service kit (Part No. 26500027) is now available to address this issue. The kit allows the primary to breath and prevents excessive pressure. Do not install inner primary vent as a preventative action. Dealer must verify the motorcycle is experiencing significant oil transfer prior to installation. This kit is reserved for vehicles experiencing this uncommon issue.
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.
