Service bulletin SIL-3267
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.

Altec has received notification from Monarch, the cylinder manufacturer, that one upper boom drive system cylinder, which carries the boom assembly load during operation, has been identified as originating from a suspect lot. Altec determined that the cylinder from the suspect lot has reached the field on an LR8 model aerial device built between September 2025 and November 2025. Monarch has asked that this cylinder be located and replaced to remove the suspect lot.
