8.3 belt tensioner problems

[xGROMx]

It seems to never end, as I'm sure everyone knows already.

After fixing a different problem, I started to hear a knocking noise. Turns out the belt tensioner is rubbing the fan clutch. I am not 100% sure how this thing is actually supposed to be installed, and am expecting it to be the wrong part installed or installed in correctly. I am constantly going behind the last people that worked on this truck.

I have found a listing of the correct part from a different thread.

Can anyone take some photos of a correct install that I can compare to?

Has a pin in the rear of the tensioner that aligns with the hole in the bracket it bolts to.

If the pin is correct as mentioned, then they may have used the wrong belt (too long), they may have it routed incorrectly, or they may be using an accessory with non-stock pulley diameter or placement, such as an aftermarket alternator.

Thanks, I'll be digging into it later. I am sure there is something bolted on incorrect.

Jbulach, from your photos it looks like I have a different fan clutch. Mine dosnt have the spacer or distace to clear the tensioner. Thanks by the way.

Fan hub is correct. In the attached pics, OP, yours is circled in red, Jbulach is in blue. That is the tensioner stop. OP, yours is at the stop that is at the "Max Tension" or Min tension, Jbulach is where it is supposed to be, almost centered between the "Min Tension" and "Max Tension". It needs to be close to the middle so the tensioner has some give in it. Your belt is too short or too long depending on which way the tensioner works. It looks like the tension is toward the hub, if that is the case, too long of a belt.

Thanks, I hadn't noticed the stop maxed out.
