[Speedjester]

Does anyone happen to know the part number for the ribbed serpentine belt on my 2004 Mountain Aire wih the ISL 400 ( mm spartan chassis)

Any help would be appreciated..

Thanks in advance..

It might be in your Cummins manual or you could contact the regional Cummins office for the number. There is a ton of belts out there as we found out when we had to replace all three this year. The one that broke was the one that Cummins didn't have in stock and had to order.

Quickserve.cummins.com can give you the cummins part number. Then you will be able to cross over to other brands. I purchased ours from rvchassisparts.com.

Steve, thanks for the information regarding the Quickserve.cummins.com. I remember the manager telling us about it in Florida. Age and memory don't always work together the right way. Thanks for the jog.

Glad to help.
Anyone that does any work on their Cummins should sign up and enter their Serial number. Has all the parts diagrams service manuals etc.... Pretty much all the documentation to work on your motor.

I believe this is your part number:
-Engine Serpentine belt 3289279, A/C belt 17475 (or 17474)

I don't know if they were that different from coach to coach. If HHIDan's number is not correct, here is the number I had for my 05 ISL - 3972263. It's also the same number as my 2014 ISL 450.


Here is Napa's Number is 080830.
