Default crank shaft sprocket

Im trying to remove the crank shaft sprocket and it isnt budging. I did a timing belt change for a friends twin turbo motor and the sprocket slide off with the help of two screwdrivers. The one on my car doesnt seem to move at all. If anyone has some suggestions on how to remove this thing that would be awsome. Thanks.

drill 2 holes in it, tap them and use a crows foot puller

thats a great idea. Thanks for the info. Man this timing belt and seal replacement job would have been easy if it wasnt for that sprocket. Changing the timing belt and cam/crank seals on the vg30dett was a bitch.

why drill, use a gear puller. they will hook over the rear belt splines. be easy and steady. works great.
When you reinstall put some lithium grease on it.

So I drilled some holes and tapped them.. unfortunately when I used the puller on the sprocket its on there so tight it pulled the heads off the bolts I was using. Im gonna try it with grade 8's tommorow but jeez man should it be fused on there that tight?

you should soak the pi$$ out of it with PB blaster, over and over and over... then if it's still won't come out then tourch it(not too much, just heat it up) and then try to pull it

After soaking thourghly with PB Blaster. Strike around the crank sprockett with a one inch or larger diameter brass punch and hammer. The shock will usely loosen the sprockett for easy removal. Before reinstall polish crank and inner sprockett with emory cloth and lightly apply anti-seize compound.
