NHTSA's recall notice
As NHTSA's recall record states it for campaign 12V572000.
Defect description
Daimler Trucks North America (DTNA) is recalling certain model year 2011 through 2013 Thomas Built non-school buses manufactured from March 2010 through July 2012, equipped with Cummins ISB6.7 diesel engines manufactured from February 16, 2010, through May 4, 2012, containing a fan pulley, part number 3914462. The subject fan pulley is part of the accessory drive system on the front of the engine. This system is used to drive such components as the refrigerant compressors, the radiator fan, and the engine water pump. The web of the pulley can fatigue over time, causing the pulley to fail.
Safety consequence
If this occurs, the fan belt may lose engagement of the water pump, allowing the cooling system to overheat. This may result in exceeding temperature limits, potentially disabling the school bus. If the school bus is occupied when it becomes disabled, the occupants would need to exit the vehicle and be transferred to another vehicle, putting them at risk of injury.
Manufacturer remedy
Cummins will notify owners of the recall. Repairs will be performed by Cummins authorized service facilities. A new fan drive pulley will be installed free of charge. The safety recall began on January 4, 2013. Owners may contact Cummins at 1-812-377-5000 or DTNA at 1-800-547-0712.
Notes
DTNA's recall campaign number is FL-635.Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
