Cummins ISX Belts, Tensioners, and Idler Pulleys


Recommended Posts

I just posted a write-up with a few pictures and parts cross-references for the belts, tensioners, and pulleys I replaced on my engine Sunday afternoon. The tensioners were replaced a while ago, but I included them since it would make more sense to do everything at once. Total cost for everything is right about $400.


I was tempted to put the old belts back on--they appear to be original, and didn't show any signs of aging or wear. Both idler pulleys had a fair bit of slop, and one of them had developed a noisy squeal in wet weather.


I struggled just a little bit getting part numbers without the help of Cummins at first--but stumbled upon listings at O'Reilly--you can put in year, make, model, and engine, just like with a car. They had all of the parts in stock at their distribution center on Cherry St.
