Took a trip today about 120 miles round trip. About a mile from home the pulley gave way and took out the belt. I didn't see any mangled wires or anything but it sounded bad until I got the engine shut down(turbo timer slowed that process).
Had the stereo cranked up so hadn't heard any noise.
Looks like it's been wearing for awhile but I just checked the belt this weekend when I was doing the oil and transmission fluid change. It looked fine and I haven't noticed any unusual noise.
Here it is.



Guess I will figure out what to do in the morning.
Hate to use my warranty for this at 80K.

 

looks like the bearing might of been a little hot huh?? I wouldnt take it to dealership i would just go buy a new one and slap it on there and run it, should be fine

 

Oh yeah that baby was cooked

 

they are an easy change out..........the sheeve is actually plastic

when ya get the new one installed check the allignment

 

It's a shame that ya can't get the Heavy duty steel sealed bearing ones from Practical solutions any more

 

How many miles do you have on your truck?

Hey Whit where is a good place to look for these? NAPA, Dealer or Cummins? It looks like I will need the whole thing. pulley, mandrel, and possibly the bracket.

 

I got mine at the Cummins store

 

Thanks you're right looks easy to swap out the mandrel/ shaft is just threaded into the cast iron bracket.
