PACCAR issued a recall on the T800 and W900 models

On certain vehicles the Power Distribution Box was manufactured with insufficient torque applied to the nut of the main power feed-through stud. Insufficient torque on the subject nut could lead to: 1) electrical arcing of wires inside of the PD Box or, 2) an interrupted power supply to the vehicle's electrical system. Either of which could lead to a loss of vehicle electrical power and possibly vehicle control without warning. Correction: The vehicles will be inspected and the nut on the main power feed-through stud will be tightened to the proper specification.
