Service bulletin M1733

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

SERVICE BULLETIN M1733: COSMETIC CYLINDER STAINING (ALL MILWAUKEE-EIGHT MODELS). PURPOSE: Initial release. This bulletin informs dealers that cosmetic staining or etching on the inside of the cylinder bore does not have an impact on engine performance, oil consumption, or overall functionality. This bulletin provides example images of cylinders with cosmetic staining, and images of cases where cylinder replacement would be recommended.
