My pickup just turned 100K the other day. I would like to do some routine maintenance, by replacing my tensioner, idler pulley and belt. I don't want this to happen:

However, when I went to the cummins shop here in Houston they told me they were not seeing an idler pulley for my pickup on their computer. So now all I have is the belt and the tensioner. I searched on Geno's Garage, but still could not find the idler pulley. Can someone point me in the right direction for a this in a quality part? Also is there anything else while I am performing this work that should be done?

Thanks for the help.

 

there is no idler pully, probably what you are calling the idler is going to be your water pump, they are not that expensive, but rarely have problems either

edit: may have spoke too soon, the one in that pic i have never seen before, maby its something different for the common rails, coal train will be here soon to let you know

 

I can see the idler pulley in all the diagrams of the pulley configuration for this motor. However, I can not find the actual part. I would post the diagram that I found here, but I do not know how to post the picture.

 

Here is the diagram I made for myself a couple weeks ago when I changed my belt. BTW, I checked the all the pulleys for free rotation and play. At 137K miles they all spun freely and had no play, so I installed the belt and a new thermostat and called it a day.

 

My idler is just starting to make some noise. Has anyone found a source for this part yet?

Can the bearing be replaced in the existing pulley?
