Recall 11V016 covers 138 2010-2011 Mci D4000, D4500, and D4505 coaches for detachable idler pulley covers. Repair is free at franchised Mci dealers.
Mci is recalling 138 2010-2011 D4505, D4000, and D4500 motor coaches because pulley covers lack welds needed to keep them attached to the coach structure. The covers will eventually fail from fatigue, and a detached cover can strike a person or object; the dealer repair will be free once available.

What's wrong?
The engine cooling fan system on 2010-2011 Mci D4505, D4000, and D4500 motor coaches uses pulleys to help drive the fan that moves air through the cooling system. A pulley cover sits over that moving hardware and is supposed to stay attached to the coach structure. Its job is to shield the rotating parts and remain secured while the engine and cooling fan run.
On affected coaches, the pulley cover lacks required welds. Those welds are the attachment points that help hold the cover to the coach structure. Without them, engine vibration and normal road movement leave the cover less firmly secured, so the cover can loosen or separate from its mount instead of staying in place.
There is no warning sign before failure. An owner or driver is not given a dashboard light, noise, or visible symptom that confirms the missing welds before the cover loses attachment.

What's the safety risk?
The idler pulley cover can fail from fatigue, detach from the coach, and fall. A falling cover can strike a person or object, causing personal injury or property damage. Schedule the recall inspection promptly and avoid standing near the cover area until it is checked. Repair will be free at any franchised Mci dealer once available.
