I bought this snow blower a while back and when I connected it to my 1450, I thought it had bad U-Joints. I bought them "Very Pricey" and took the shaft out and I have discovered that the output shaft on the right angle gear has the key way wallered out. Is it worth taking to a machine shop to fill it in and machine it back to new, buying a good used gearbox "if I can find one," or try to find another snow blower?
