The fastener can be a HuckBolt or a hex bolt and nut. Movement of the U-bolt can possibly cause damage to the HuckBolt or hex bolt and nut resulting in the fastener being broken off. Altec requires the customer to perform an inspection of the rear shear plates on both sides of the subbase to determine if HuckBolts or hex bolts and nuts were installed and if there is interference with the U-bolts. The inspection procedure included in the SIL should be completed no later than 90 days after the receipt of the SIL.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10187972-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10187972-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10187972","components":[{"id":"suspension","name":"Suspension","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"ALTEC","model":"AERIAL DEVICE","year_from":2016,"year_to":2018,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
