What’s wrong with it?
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.
CUMMINS IS RECALLING CERTAIN ISB6.7, ISC8.3, ISL9, ISX11.9, AND ISX15 ENGINES SHIPPED FROM SEPTEMBER 2010 THROUGH DECEMBER 2010 TO VARIOUS VEHICLE MANUFACTURERS.
THESE ENGINES WERE INSTALLED IN RECREATIONAL VEHICLES, EMERGENCY VEHICLES, BUSES, AND CERTAIN TRUCK APPLICATIONS.
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.
