I'm in need of a drive pulley.  2300 series Peerless transaxle, 4 speed.  Pulley OD 7", Shaft size 3/4" (measures 0.740")  Front face to back face 3 1/2", cast iron.  Mounted on the input shaft of the rotation reverser gearbox on LH side of transaxle.  Mine loosened up and tapered the shaft bore.  Temporary "shim" made from a piece of hose clamp which took out almost all of the wobble.
Cheers,
