Drive Chain

An endless (riveted master link) chain connects the countershaft and rear
wheel sprockets. The O-ring chain uses rubber rings between the side
plates of the pin and roller links to seal in the manufacturer-installed
lubricating grease and keep out moisture and dirt.

adjustment. Poor maintenance can cause premature wear or damage to
the drive chain or sprockets.

recommended service in the Maintenance Schedule.
