# Service bulletin SIL\-3214

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 the king pin towing capacity placard might not be installed on certain DL derricks built from August 2005 to October 2024. This could lead to unintentional overloading which could result in cracks or deformations to the king pin assembly. Altec has had no reports of this issue occuring. This area should be inspected regularly as outlined in the Welds and Fasteners subsections in Section 4 of the unit’s Maintenance and Parts Manual.
