Can someone tell me what the difference is between these two crankshafts? 493362 and 797018. I think 797018 replaces 493362, does anyone know what was changed? Thanks
 
give us the engine model and code it is going in.

Amazon has a listing for the 797018 part and it is sold by the Briggs and Stratton Store. They are a retailer whom Briggs and Stratton uses to sell their parts. Says it fits most 122000 and 126000 series engines.
 
Maybe this will clear the air.

Main difference is the key way and key slots. Key way changes from 1/4" [493362] to 3/16" [797018]

Looks like I would have to get a different adaptor to hold the blade since the key ways are different sizes. Thanks for the information.
 
some say crankshaft gear. My 120000 series mower has a crankshaft, and a slide on gear that has its own key. Some may have the gear cast into the crankshaft, or perhaps a different way to mount the gear based on the list above. Need to look it over carefully.
