NHTSA Service Bulletin 10172174: Altec Altec
Official manufacturer communication context for model years not specified Altec Altec, with affected products, buyer checks and links into Carchieve recall, problem and VIN research.
Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
Altec has discovered that the serial number placard at the lower controls was stamped with incorrect slope limit values for Crane Mode. The slope limit placard at the tail-shelf was stamped correctly. The discrepancy between these placards could cause confusion for the operator when setting up the unit for crane operation. Altec has created the Crane Slope Limit Correction Kit, part number 991011668, containing steel stamps to correctly re-stamp the placard. Altec requires that the kit be used to make this correction no later than the next regular maintenance interval or 60 days from the receipt of this SIL, whichever comes first.
