Service bulletin CSR 510

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Cummins Inc. has decided that a defect that relates to motor vehicle safety exists in certain B6.7 diesel engines manufactured between December 16, 2015, and March 24, 2020, and equipped with fuel module option FS90301 or FS90453. Cummins has released field Safety Campaign #C2302 "86.7 Engine-Mounted Fuel Heater Safety Campaign" to correct the condition detailed in the attached Cummins communication. This safety recall addresses the potential safety defect for your engine. However, this repair will disable the fuel heater. Cummins is currently working to determine an appropriate cold-weather starting aid for customers that require it. Cummins Distributors and Dealers will be notified when a separate field action is available. Contact the nearest Cummins Distributor or authorized warranty dealer to arrange to have this campaign performed on your engine. In the meantime, to mitigate the safety risk, Cummins has advised action. Altec is not able to complete this repair. All work must be completed by an authorized Cummins Distributor or authorized warranty dealer.
