mp122 belt tensioner alignment question
Well installed the blower few months ago, and i managed to shredded a belt -found that one of my pulley is not offset enough so the belt was hanging off a little. well i went to auto store got another pulley with 3mm more offset which its closer but the belt still hangs off like a 1/8- 1/16 . i used stock idler like the instructions said. any ideas or part numbers i can use to fix this problem? i dont want to do the same thing to the new belt. heres some pics. the pulley i have issues with is the one with the green seal.
before i changed idler
the idler that caused the damage- bad pic
new one
the offset and over hang

Sorry I was looking on my phone, and it looked like the water pump pulley. Afrer looking closer it appears to be the passenger idler. If there is the worn area in front of the belt it is telling you that at one time it was riding at the edge of that worn area. Now that the worn area is ahead of the belt it is telling you that something is moving. I would remove the belt and check all the pullies and idlers for any play. If there is play the bearings or the idlers need to be replaced. The cheapest easiest way I feel to check for alignment is with a straight edge. Place the belt on and run a straight edge across the pulley, and parallel with the belt. If it is off, it should show up pretty easily.

Thanks for the replies!! Yes the pulley needs to move back towards the motor. I was also wondering about having to mill the bracket. I was just hoping for a pulley swap! Is this a common issue? Blown06 thanks for the offer I'm going to check with a neighbor that has a Bridgeport first.

So took the truck out today, the pulley looked worse than before I loosened set bolt the pulley had some play in it. Reset it and now it's straight. So took it out for the Woodward dream cruise put about 60 miles on it and rechecked it everything is still straight. Just have to see how long this lasts.
Thanks for the help again guys
