This is the friction disc shaft/pinion from a Honda HS80 snowblower, also used on the other HS models such as 50, 55, 70. It is in excellent condition with lots of life left. Spline and gear teeth are in great shape. This is an important part which sometimes fails, leaving you with no usable transmission. This part has not been available from Honda for a long time and grows rarer every year. Please ask if you have any questions. I have many more parts for these machines, let me know what you need!
