Service bulletin SIL-3209

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 velocity fuse, part of the HOP plumbing on the lower boom lift cylinder, may close and fail to open due to air in the circuit during normal operation on certain D3000H, DT65H, and DT85H series derricks built from July 2022 to May 2025. This can prevent the hydraulic overload protection system from operating properly to prevent a structural overload of the boom.

The document

• NHTSA's copy of the document (PDF)
• If that address does not open, try this one

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
