This is a nice complete auger set for MTD built machines including yardman. Came out of a 12/30 snowblower with ez steer. Used, as is condition. Input shaft spins gearbox smoothly. 1/2” V pulley .875x 10.12 756-0243, self aligning bearing 941-0185, impeller fan 684-0090B, input shaft 711-1133, upper worm gear 917-0299, RH housing 918-0246, LH housing 918-0247, lower worm 917-1425, worm gear shaft 738-0275, auger shaft is listed as 33” 738-0491. I do not know if that part number is correct as this came out of a 30” cut machine. Includes gearbox support and bearing retainer as well as shaft end bushings and retainers. Please use part numbers to determine fitment. Input shaft may be removed from gearbox to reduce shipping.
