  If you are looking for a unicorn they have it. I spent hours looking for a part and was getting nowhere. I called Rocky Mtn cummins and was able to get it right away! They had 2 on the shelf! (Yes i left the other one) Went out to Job-site, cooling fan bearing mount assembly went on like a glove and the ole 12 valve was purring again. Back to work!

  I took my newly acquired Freightliner M2 with a Cummins engine to Cummins Sales and Service in Reno because I suspected the turbocharger had failed. From the beginning, Tracy at the service desk was friendly, professional, and very helpful. I explained what I thought the problem was, and he assured me they would thoroughly check it out. The very next day, right when he said he would call, Tracy contacted me with the results. The turbo was perfectly fine. Their technicians diagnosed the issue, cleared some fault codes using Cummins INSITE diagnostic software, and got me back on the road. What impressed me most was their honesty and integrity. I was preparing myself for a repair bill of $7,000 or more, but instead they fixed the actual problem for less than $500. It would have been easy to replace expensive parts I didn’t need, but they earned my trust by doing the right thing. If you’re looking for knowledgeable, honest, and efficient diesel service, I highly recommend Cummins Sales and Service in Reno. They have definitely become my go-to shop for diesel repairs.
