    Let's play guess this noise

    About 24 sec. It has a wine/ how noise and I don't know what it is if I pull the blower belt off it goes away I've replaced both idler pulleys on the bridge so maybe the tensioner needs replaced or bearings in the blower

    take the belt off and rock the eaton pulley back and forth, if it clacks/has slop you probably need the eaton snout rebuilt.

    The snout of the eaton has gears in it that wear out, causing slop and weird noises.

    Wat "Blind" said....behind snout are helical gears that take motion from belt and pulley shaft and turn the two blower rotors
