I'm not sure of your question so are just trying to get the pulley off?

Customer: replied 8 years ago.
yes just trying to get the pulley off because it broke in half
Expert:  ZZDaryl replied 8 years ago.

That allen bolt you are talking about is actually part of the shaft of the power steering unit, the pulley is pressed on to that shaft. It requires a special tool to pull it off but if the pulley is broken you may not be able to pull it off. Pic below

i picked up a puller when i bought the pulley and yes the collar is still there, the pulley split just to one side of the collar, when i read over the directions for the puller it said i had to use a threaded screw to install the new pulley thats why i was trying to take the allen screw out even in the picture it looked like that allen screw had to come out. will there be possibly any damage to the pump with trying to take out the allen screw?
Expert:  ZZDaryl replied 8 years ago.

There could be from the heat if you got the front seal to hot.

The threaded screw is just to install the new pulley and should fit right through the center of that allen hole and screw into the pump shaft.
