I have a p600 charger that I cannot keep a belt on.It shreads the belt on one egde and it comes apart.It does not throw the belt off it just shreads it.I have changed the tenssioner,pullies,realined the pullies etc.Thanks for any help

 

check pulley alignment with a straight edge, or better yet (if you can borrow one) a laser aligner. also check for bracket flex. grab the blower and try to flex it. i have seen them move 1/2"

 

You need to make sure your blower pulley is not walking. I would remove the blower belt and make there is no play in your blower pulley. If there is then I would say it is time for a blower rebuild.

If that is not the case you may want to look at getting a SD concepts spring loaded tensioner.

 

My fan shroud would catch the edge of the belt. I took the old dremal tool out and went to town on the shroud and it now works great. It has been years since I have the problem. Hope this helps.

 

Thanks for the help guys.I think I will check the alignment again.I changed that when I put this belt on and I have just noticed the back off the belt is shreading this time.The last two belts shreaded on the front.I forgot to mention this is a 12 rib system.If that matters.Thanks again.
