- Summary
- E-ONE IS RECALLING CERTAIN MODEL YEAR 2010 AND 2011 TYPHOON AND CYCLONE II AND MODEL YEAR 2011 TRADITION AND QUEST FIRE FIGHTING CHASSIS MANUFACTURED FROM NOVEMBER 24, 2010, THROUGH JULY 13, 2011, EQUIPPED WITH A CUMMINS ISB, ISL, ISC, or ISX 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.
- Consequence
- This could result in asphyxiation or carbon monoxide poisoning. The heat build up from the exhaust can also result in 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.

Has your E-One been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A E-One dealer can also check your VIN. Recall repairs are free.
