Posted on: 2015-05-11
Description
Mack trucks, inc. (mack) is recalling certain model year 2011-2016 mack mru and leu trucks manufactured june 25, 2010, to april 30, 2015, and 2015-2016 lr6 trucks manufactured from december 18, 2014 through march 6, 2015. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.
Consequence
If engine oil comes into contact with a hot surface, there could be an increased risk of a fire.
Corrective Action
Cummins will notify owners on behalf of mack, and cummins service centers will administer the repairs which include securing the ends of the 90-degree elbow and reprogramming the electronic control module (ecm) with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on june 12, 2015. Owners may contact mack customer service at 1-800-528-6586 or cummins inc. At 1-800-343-7357.

DEFECT #5 - PARKING BRAKE:DRIVELINE:HYDRAULIC:ACTUATOR
Posted on: 2015-01-22
Description
Mack trucks, inc. (mack) is recalling certain model year 2015 and 2016 cxu and leu trucks manufactured may 20, 2014, to march 24, 2015, equipped with certain haldex life seal type 30/30 long stroke air brake actuators manufactured from january 9, 2014, through february 3, 2015. The affected actuators may have an incomplete attachment of the internal rubber diaphragm to the actuation mechanism of the parking brake section of the life seal actuator.
Consequence
If the diaphragm is not completely attached, there may be internal leakage from the service section past the diaphragm, potentially trapping air pressure in the parking brake section. This air pressure in turn, if not vented, may prevent full release of the actuator unit, and may induce brake drag and may result in overheated wheelend service brakes, increasing the risk of a fire.
Corrective Action
Mack will notify owners, and dealers will inspect the brake actuator and replace, as necessary, free of charge. The recall began march 20, 2015. Owners may contact mack customer service at 1-610-709-2131. Mack's number for this recall is sc0387.
