If you are running an 8-rib, you might want to consider doing something more than just welding the end of the pulley. I did that on mine and this is what failed next...

The new fix was to weld the pulley at the shaft, machined all the threads off, then sleeve a piece of custom machined DOM over the pulley and welded it at the base and the end and that seems to be holding well...
