NHTSA recall 11V411000
Engine and engine cooling
Gillig Low Floor
The defect
Gillig IS recalling certain model year 2010-2011 lowfloor buses equipped with cummins engines. the v-band clamp assembly 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.
The risk
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 remedy
Gillig IS working with cummins to identify owners. cummins IS handling the owner notification and remedy for this campaign please see nhtsa recall 11e-031. owners may contact cummins at 1-812-377-5000.
