9999 CUMMINS ISB6.7 Recalls (5)

Campaign:
11E031000 on 08/08/2011
Component:
Engine and engine cooling
Affected:
11,860
Defect:
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.
Consequence:
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.
Correction:
Cummins is working with the vehicle manufacturers to identify and notify owners. the safety recall began on october 10, 2011. owners may contact cummins at 1-812-377-5000 or their vehicle manufacturer.
Notes:
Cummins' recall campaign number is c1154.owners may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (tty 1-800-424-9153), or go to <a href=http://www.safercar.gov>http://www.safercar.gov</a> .
Campaign:
12E054000 on 11/28/2012
Component:
Engine and engine cooling:engine:diesel
Affected:
7,040
Defect:
Cummins is recalling certain model isb6.7 diesel engines manufactured from february 16, 2010, through may 4, 2012, equipped with fan pulley part number 3914462 and installed on certain thomas built buses, inc. school buses. the subject fan pulley is part of the accessory drive system on the front of the engine. this system is used to drive such components as the refrigerant compressors, the radiator fan, and the engine water pump. the web of the pulley can fatigue over time, causing the pulley to fail.
Consequence:
If this occurs, the fan belt may lose engagement of the water pump, allowing the cooling system to overheat. this may result in exceeding temperature limits, potentially disabling the school bus. if the school bus is occupied when it becomes disabled, the occupants would need to exit the vehicle and be transferred to another vehicle, putting them at risk of injury.
Correction:
Cummins will notify thomas built of this defect and the potential safety consequences, and will work with them to identify and notify the affected owners. cummins will install a new fan drive pulley, without charge, through cummins' service network. the recall began on november 27, 2012. notification to owners began on january 4, 2013. owners may contact cummins at 1-812-377-5000.
Notes:
Cummins' recall campaign number is c1296.owners may also contact the national highway traffic safety administration vehicle safety hotline at 1-888-327-4236 (tty 1-800-424-9153), or go to www.safercar.gov.

Defect:
Cummins inc. (cummins) is recalling certain isb6.7, isl9, isx12 and isx15 engines. the affected engines have an engine control module (ecm) that may short circuit and blow a fuse resulting in the engine stalling without warning.
Consequence:
An engine that stalls without warning increases the risk of a crash.
Correction:
Cummins will notify owners, and dealers will replace any defective ecm with a remedy part, free of charge. the recall began on october 22, 2015. owners may contact cummins customer service at 1-800-343-7357. cummins' number for this recall is c1698.
