All other locations in the manual contain the correct torque value of 65 foot-pounds (88 N•m) for these cap screws. Torquing these cap screws to 250 foot-pounds (339 N•m) can result in breaking the bolts during rotation gearbox installation or maintenance. The Maintenance Manual has been updated to show the correct torque value.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10246355-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10246355-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10246355","components":[{"id":"equipment","name":"Equipment and accessories","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"ALTEC","model":"AERIAL DEVICE","year_from":2020,"year_to":2023,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
