This Service Bulletin describes the new belt tension specification to use for belt tension before the first service interval. Belt tension is initially set to allow for early break-in of the belt and sprockets. The break-in occurs in the first few hundred miles and even to some degree in post assembly audit. Harley-Davidson has provided an acceptable range of belt tension variation at PDI based on testing and evaluation.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10115980-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10115980-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10115980","components":[{"id":"engine","name":"Engine","parent":null},{"id":"drive-belt","name":"Drive belts","parent":"engine"}],"codes":[],"topics":["maintenance"],"vehicles":[{"make":"HARLEY-DAVIDSON","model":"HARLEY-DAVIDSON","year_from":null,"year_to":null,"match":null,"vehicle_ids":[]},{"make":"HARLEY-DAVIDSON","model":"TOURING","year_from":2017,"year_to":2017,"match":null,"vehicle_ids":[]},{"make":"HARLEY-DAVIDSON","model":"TRIKE","year_from":2017,"year_to":2017,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
