Defect
On large tour buses, the lower bracket securing the hydraulic fan drive oil reservoir tank was manufactured using material with an incorrectly thin plate thickness. This causes cracks to develop in the upper bracket due to vibration during driving. Continued use can then cause cracks to propagate into 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. Replace all associated bolts and nuts with new hardware.
