Recalls for OEM Parts Terex Hrm

DEFECT #1 - EQUIPMENT

Posted on: 2007-01-04
Description
Certain terex telelect digger derricks and aerial devices equipped with check valves with p/nos engraved on the valve of; 1904f, 1908f, 1910f, and 1910r.  These valves can fail which can cause the parts to move through the hydraulic system or will allow a vacuum to form in hydraulic lines if the pump flow should stop.  These devices are installed on trucks to transport the aerial device or digger derrick to the work site to facilitate working on electrical power lines and communication lines or to trim trees.  

Consequence
Failure of the check valve can result in unexpected boom platform movement after the control lever is returned to the neutral position, or allow vacuum to form in hydraulic lines to the boom tip and could cause potential dielectric failure, possibly resulting in death or serious injury.

Corrective Action
Terex utilities will notify owners and replace the check valves free of charge.  The recall began on march 22, 2007.  Owners may contact terex utilities service department at 1-605-882-4000.
