Service bulletin SIL-859

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 on AH75/85/100, AH75A/85A/100A, and HL125 aerial devices built from November 2003 to January 2021, there is potential for the jib rotational positioning pin to disengage when the platform is tilted down 90 degrees or more from the level working position. This is due to the combination of wear to the edges of the jib indexing plate pinning holes during use and vertical clearance in the jib pivot due to manufacturing tolerances. Altec has developed a kit which provides a new jib rotational positioning pin with greater engagement and adds spacers to limit the vertical clearance in the jib pivot, for use if inspection shows it is required.

The document

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.
