Service bulletin SIL 3123

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Altec has learned that Section 9 of the Maintenance and Parts Manual for Certain AC45E cranes built from September 2020 to November 2023 contains an incorrect torque value of 250 foot-pounds (339 N•m) for the rotation gearbox mounting cap screws. 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.
