Side to side belt deflection 2 stage blower

[Hydro 130]

I was noticing there was a fair bit of belt residue on the belt cover of my 2 stage. Considering I haven't used it this much I found that a bit odd. In looking over the belt configuration I noticed the top idler pully is out of alignment as is the steel plate it's anchored to. When you look at the photos you will see the belt running off the left side of the pully.

Is this a problem? Looks like it came that way from the factory. I would appreciate anyone's thoughts on whether it should be corrected and how to go about it if necessary.

Thanks Guys.

Definitely isn't running true, is it Gary?

Other than shimming the pulley or tweaking it's mount, how could you correct that?

Yeah Craig. I'm thinking the plate could be heated or a special shim could be machined but I guess before I go to a whole lot of trouble and expense...does it really matter is the question? I think it does I'm hopin the experts will tell us.

well as you stated its gonna be hard on the belt,it will over heat it and shorten its life and probally pop off when it gets older,i had thid on my tiller,i had to bend the bar and shim the idler,i have a single that is crooked like that too and it wore the belt in no time,cant be good for the pulley either

Hi there, I've been watching this sight for a couple of years and a fairly new member and this my first reply. My 2 stage had the same problem and a couple others. That plate will bend pretty easy, try a 12 or 15 inch cresent wrench, adjust to fit the thickness and push the upper corner inward. If it still doesn't look quite right pull the plate outward between the pulley and tractor the same way or with a large dead blow hammer. It might take a few back and forths. Essentially all your trying to do is get the small mounting surface of the pulley parallel and square with the drive line. Your idler tension and gearbox pulleys look real good in line with the set up, both of mine were really bad. Hope this helps Hydro.

Thanks Craig for your input, don't be shy...with advice like that I hope you participate more often! I wondered about bending the metal, I also wondered about some type of a wedge shim. On a brighter note I guess that big 16 Kohler single just yanked that pulley right out of alignment :laughing-rolling:
