Plain-English summary

North American Bus Industries (NABI) is recalling certain model year 2010 and 2011 416 transit buses manufactured between September 1, 2010, and February 28, 2011. These vehicles are equipped with a Cummins ISL diesel engine. The recall involves 87 affected units.

The defect involves the V-band clamp assembly used to connect the inlet and outlet cone sections to the diesel oxidation catalyst (DOC)/diesel particulate filter (DPF). The T-bolt in these assemblies can fracture and fail when subjected to stress or load. If the T-bolt fails, the clamp may loosen, causing the inlet or outlet sections to disconnect from the DOC/DPF housing.

If the sections disconnect, hot exhaust gases can vent before exiting the tailpipe, creating a risk of combustion and fire. In some applications, if both clamps fail, the DOC/DPF housing may detach completely, creating a road hazard. NABI is working with Cummins to identify and notify owners. Repairs will be performed by authorized Cummins dealers free of charge. The safety recall began on October 10, 2011. Owners may contact Cummins at 1-812-377-5000 or NABI at 1-256-831-4296.
