Replacing broken a/c belt on Kubota M8200 Tractor

[DouglasPruett]

There are 4 pulleys, drive pulley, A/C pulley, tension pulley & a small idler pulley. I do not now which side to put the belt on this pulley.

Something close to this.

I would think if the idler pulley is a v pulley, the v part of the belt would run on it. If the idler pulley has a flat surface the back side of the belt would run on the flat side of the pulley.
