Help with welding crankshaft

Another alternative would be to build it up with bronze brazing. Its easy to work with and machine and the heat won't be so localized or intense. Let it air cool slowly.

Mill it out oversize, and make a step key, did it all the time on other application

That works good too. Ray

When a key way is worn it can only be due to the pulley being loose(loose nut,bolt). When the pulley is loose it wears the inside of the pulley as well as the outside of the crankshaft. It does not help to cut another key way opposite as the key does not secure the pulley,it is only for timing marks to be in the right position. You have to replace the pulley and braze weld the crank point and cut the key way in the correct position.

If the pulley is worn just make a over size key for both the pulley and the crank, if only the crank is worn make the step key, no brainier, why weld something and take a chance of it warping.

What about just reducing the end a little to clean it up & make a new pulley. If you do this first you can still try & get the crank welded if it does not work.:thinking:
