The part sticking out of the cogged pulley? Grab it with a pair of vice grips, and then try and hammer it out. I am going to guess that the threads in there are trashed though, so, before you try and run a bolt into that, I would run a bottoming tap into it first.

 

Ok.i guess hit it from underneath is my best bet.i was thinking the threads r messed up.how do u get that collar off.the shinier looking one

 

Isn't that the crank snout? The pulley should just slide on over it..... Of course, if it has been there a while, it'll be reluctant to come off.

 

The pulley came off but those 2 pieces r not moving.that cog looking piece just breaks when i try to use a puller

 

Why does it need to come off?

 

We r changing the timing belt

 

Leave it there then. If the seal behind it isn't leaking, don't worry about it.

 

Should i cut the extension closer to the chrome piece

 

No. Don't cut it at all. Grab it as far out as you can, set the vice grips as tight as you can, then try tapping it with a hammer such that it is trying to knock it as straight out as possible.
