Have Truck Repair Questions? Ask an Expert
Hello! I will be glad to assist you with this question, I believe this is an NTC290 correct? Have you called Cummins directly? I am not sure where you are located but you can go to www.cummins.com and search for a distributor in your area. My local Cummins facilities phone number is(###) ###-#### ***** are open until 10pm here in California. This particular engine may no longer be listed in the Quickserve system however the Cummins facilities do have parts book that they can look thru to find your part numbers. Also, these parts manuals may be available for purchase thru Cummins directly. Otherwise any Cummins dealer (such as Freightliner, Peterbuilt etc) should have access to older Cummins part information in their systems. If not they too will know who to call. You also have the option of calling 1 800 DIESELS as they have a technical line as well. I hope that this helps! If I can be of further assistance please let me know. Thank you
