Unless the chassis has been modified (drilled more holes) it isn't necessary. The center axle on the AM14U2 is only dropped 1/8". Since the corner wheels are 2" larger diameter, the 4" center wheels float 7/8" off the carpet. In effect, the 4" wheels are just a spacer for the belt sheaves.
We did something similar with our H-drive, though since we used 4" wheels on the corners, we cut the rubber off the center wheels so they would float.
