Mci recall: Engine and engine cooling
What is wrong
Motor coach industries, inc. (mci) is recalling certain model year 2011 e4500 and j4500 motor coaches manufactured from december 2010 through january 2011, equipped with a cummins isx 11.9 diesel engine. The v-band clamp assembly, part numbers q187684, q187685, and q187686, used to connect the inlet and outlet cone sections to the diesel oxidation catalyst (doc)/diesel particulate filter (dpf) include a t-bolt which can fracture and fail when subjected to stress or load. A fracture or failure of the t-bolt may cause the clamp to loosen and the inlet or outlet sections attached to the doc/dpf housing to disconnect.
What could happen
If the inlet or outlet sections disconnect, hot exhaust gases can vent prior to exiting the tailpipe, creating the risk of combustion and a fire. If both clamps fail, there is a risk in some applications that the doc/dpf housing may detach completely, creating a road hazard.
The fix
Mci will notify owners, and repairs will be performed by authorized cummins dealers free of charge. The safety recall began on september 19, 2011. Owners may contact mci at 1-800-241-2947 or cummins at 1-812-377-5000 for more information.
