Paccar Inc. is recalling 4,914 Peterbilt Model 579 Class 8 tractors which have experienced six under hood fires. A misplaced fastener can chafe alternator cable insulation. No injuries or deaths have resulted.
On certain Model 579 trucks equipped with a Paccar MX-13 engine and Paccar 160-amp alternator, the alternator positive cable may chafe against the left-hand side front spring bracket top rearward fastener. The top of fastener could also be outside of the frame rail.
If the cable was routed too near the left-hand front spring bracket top rearward fastener, a hearth could result.
All recalled trucks are suspected to have the condition, for which there isn’t a warning.
Peterbilt began an investigation May 11 after learning of a customer with an underhood fire. A guaranty claim search found the opposite fires leading. The Peterbilt Safety Committee decided June 6 to conduct a recall.
Paccar dealers will replace at no charge the frame fastener and install it in the other way contained in the frame rail and secure the alternator cable, creating greater routing clearance. The Denton, Texas, plant made a running change on July 29, 2022, to show across the front of frame bracket fasteners.
Dealers and owners shall be notified of the recall Aug. 11. The National Highway Traffic Safety Administration recall number is: 23V-423.
