An oil leak that poses a fire risk prompted Cummins Westport to issue a recall that is scheduled to begin Nov. 20 for certain ISL G engines which are found in some Mack and Navistar medium duty trucks, according to the National Highway Traffic Safety Administration (NHTSA).
These natural gas engines, manufactured between Sept. 13, 2007 and September 23, 2015, have a turbocharger oil supply line that may contact or interfere with the turbocharger inlet elbow, clean air intake clamp, or the air fuel control tube, and result in an oil leak in the proximity of the engine exhaust manifold which poses an increased risk for fire.
Mack Trucks that are effected include certain models of Granite (GU), LR and TerraPro (LEU, MRU) trucks manufactured between Nov. 17, 2009 and Oct. 17, 2015.
Effected Navistar trucks include certain model year 2013 to 2015 International TranStar trucks manufactured between April 10, 2012 and Dec. 12, 2014.
The affected engines were sold for use in Mack Trucks and Navistar vehicles, both as original and replacement equipment.
Cummins will notify owners on, and dealers will inspect oil supply line interference or damage, eliminating the interference and replacing the oil supply line, as necessary, free of charge. The recall is expected to begin Nov. 20, 2015.
Owners may contact Cummins at 1-800-343-7357. Cummins’ number for this recall is C1673.
The Cummins Westport NHTSA campaign number for this recall is 15E085000; Mack NHTSA campaign number 15V702000; and Navistar NHTSA campaign number 15V438000.
