Never tried but does it need special tools like these? http://www.ecstuning.com/ES11415/

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

It came with a single tool just a17mm to the big splines in the center and instructions that's how I got it off but no go tightening it down ,now it's ruined and won't go back on at all

Would it be safe to fix the thread on the shaft with a die the part on the end is gone?

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.

How big is the hole on the double tool 1/2 in or less thanks

The inner diameter of the larger tool section is 1 cm or about 7/16 inch.

I had to use a die on the shaft thread while holding with a10 mm triple square hard to keep it straight. I made a double tool I have a mini lathe then I wrenched it tight.
