Here's a good Craftsman auger box 22 tooth brass gear that came off a 1979 Craftsman 5/22 two stage snowblower.  This assembly fits many other Craftsman and Dynamark 5/22 and 4/20 models as well, so please check your applications. See pic. 14 for model id. This auger gear still worked well on the blower.  It installs tightly to the auger axle and securely positions with the included key.  The gear will engage the steel worm the and spin out round with some light normal run-out common to these. The gear box shows some normal wear, but is evenly distributed on all the teeth.  No cracks or missing teeth. These gears are nice to have as a spare in a pinch when one is needed!  These OEM units are getting difficult to find anymore in good working condition. Look for other good parts from this vintage Craftsman 5/22 blower as well.  Please thoroughly clean and lube prior to use.  Look for more good snowblower parts in my other auctions.  Please look at the pictures.  Ask any questions that you might have.  Paypal payment due within 48 hrs of auction ending.  Securely packaged and quickly shipped.  Thanks for looking.
