Service bulletin SIL 844

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 there could be loose, missing, or incorrectly installed mounting fasteners on the electric power take-off (ePTO) on certain aerial devices built from 2015 to 2020 and equipped with a JEMS 18E20 hybrid system. This can cause the ePTO to become loose from its mounting bracket, resulting in excessive vibration. The fasteners may need to be replaced with new, correctly installed fasteners. Customers should inspect the ePTO mounting fasteners no later than the next preventive maintenance interval or 120 days from the receipt of this SIL, whichever comes first. If repair is required, order and install the specified mounting kit or schedule the installation of the kit by Altec. If cap screw(s) are missing, take the unit out of service until the kit has been installed.
