| Date filed | November 13, 2012 |

Defect
On large touring buses, the lower bracket securing the hydraulic fan drive oil reservoir tank was incorrectly manufactured using material that is thinner than specified. Vibration during driving causes cracks to develop in the upper bracket. Continued operation progresses the cracking to the lower bracket and the oil reservoir tank itself and, in the worst case, the oil reservoir tank may detach from the vehicle.
Corrective action
On all vehicles, replace the lower bracket with a conforming part and the upper bracket with a new part, and replace all associated bolts and nuts with new hardware.
