So it didn't stay on with electric impact wrench now what . I'm gonna try to torque it by hand if I can get it back on same part number as what came off 5 th revision looks messed up inside compared to the old one ouch


Unless you torque it with the tool Ahsai mentioned, it is never going to stay tight.  You need the double tool:

Both the alternator shaft and the declutching pulley assembly are internally splined, hence the special tool, which holds the shaft still while the other part of the tool tightens the pulley in place.


This is what the pulley should look like, and the tip of the shaft should be a similar but smaller internal spline as well:




If the treads on the shaft are buggered, you could use a die to clean them up (I have no idea of the size or pitch however), but if either internal spline is damaged, I don't know how you are going to repair them.
