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.

Incident: December 12, 2012 · Filed: February 27, 2013

THOMAS BUILT BUS - SAFE-T-LINER C-2: TWO INSTANCES IN LAST 4 MONTHS OF CHILDREN SLIDING FORWARD OUT OF THEIR SEATS AND BECOMING WEDGED ON THE FLOOR BETWEEN THE BOTTOM OF THE SEAT SUPPORTS. EACH INCIDENCE REQUIRED APPROXIMATELY 3 MINUTES TO EXTRICATE THE TRAPPED ELEMENTARY SCHOOL CHILD. I BELIEVE THAT FRONT TO BACK SEAT SPACING IS TOO TIGHT. IN AN EMERGENCY, THIS COULD BE A CONCERN. *TR
