Summary: Sutphen corporation (sutphen) is recalling certain model year 2010 SL75 and model year 2010-2011 pumpers and rescue firefighting vehicles, equipped with a cummins isb, isx, or 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: 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.
Remedy: Sutphen is working with cummins to identify and notify owners of the recall campaign. Repairs will be performed by authorized cummins dealers, free of charge. The safety recall began during October 2011. Owners may contact cummins at 1-812-377-5000 or sutphen at 1-866-287-5549.
Notes: Cummins recall campaign number is C1154. Customers may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-423 (TTY 1-800-424-9153), or go to http://www.safercar.gov.

Has your Sutphen 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.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Sutphen dealer can also check your VIN. Recall repairs are free.
