Tried looking up belt/tensioner on cummins quickserve, doesn't list them for my engine for some reason.

Current tensioner is marked Dayco 2351230 / 3976832, gonna try and replace with same dayco pn. Might have to do some digging around on the belt #.

For some reason it seems not every part is in customer version of quickserve, If you call any Cummins dealer with Engine s/n you'll get correct part number as well....

Is your coach a side or rear radiator? Your engine S/N in quickserve shows a engine mounted fan drive....
Probably best to call Cummins dealer in your area and get part numbers for belts and tensioner......

EDIT: I found it, using your engine S/N
Belt # 3926866
Tensioner # 3922901

I'd say those numbers are correct from Cummins, the ones in quickserve often get updated

Edit- using quickserve cross reference the belt are same....

Got a Gates Tensioner and Serpentine Belt on order, be here tomorrow. I did pickup the pulley for the AC idler, it's Gates PN 38015, it looks correct but haven't bolted it on yet. I'll swap this stuff out tomorrow night and see if I've got the right PN's.

Finally found the Idler and belt info, was under "Electrics", Alternator Drive. Shows OE# 3926866 for the belt which crosses over to Gates K080638HD and OE#3922901 for Tensioner which has two PN's, the HD tensioner is Gates 38513

Success!

No more noisy belt... Nice and quiet now.

I did find out the replacement pulley for the AC compressor V-belt wasn't the same as what was on there. The old one was a v-belt pulley, the new Gates 38015 is a flat pulley that runs on the outside of the belt. It interchanged, and seems to work fine.

I have tried to create a QuickServe account but have not gotten the temp password mailed back to me. An hour has passed. Is this what your setup looks like?

Part numbers?

Stuff I used is posted above... Note the AC tensioner replacement I got works on the other side of the belt, see video.
