Anyone have the correct part number for the tensioner pulley on a 2002 F250 with 7.3 diesel (single alternator if it matters).

Replacing my serp belt soon and thought I should replace this too.

 

Readily available at Autozone for ~$25...either smooth or grooved depending on what you need. I used a Duralast on my 94.5 PSD when it broke....lasted ~4 yrs and was still fine when I sold it. I'd put one on my '02 if I needed one.

....and I just realized you said TENSIONER, not Idler ;-) Idler is what I was referring to, my bad ;-) But for what its worth they show the Tensioner Pully for ~$65.

 

a lot of us use parts from some of FTE's sponsor's

The link worked when I tried it, but try this one if you need. If not the are under the OEM section.

Thanks for the link... good price.

 

So does the spring wear out or just the bearings? I pressed new bearings into mine a couple years ago as a preventative measure and everything seems to be fine.

 

Some of the youtube videos show that the unit "separates" somehow. I wanted to get a new one in there along with the serp belt so I'd have a baseline going forward.

 

Just pressing in new bearings is cheaper, and if I know how to check if my tensioner isn't separating I'll do just that.
