Don’t let a frozen crank pulley bolt stop your timing belt change in its tracks.

Loop the old accessory belt around the crank pulley.
Run both sides of the belt over an available accessory pulley.
Anchor the other end of the loop on a third pulley.
Rotate the crank pulley and take up the belt slack by letting the crank pulley end pinch the belt under itself.
When the last of the slack is gone, the belt should immobilize the crank pulley completely, allowing you to apply gobs of bolt-loosening torque.

Dang that's handy. But anyone got a crude diagram?

Take a closer look at the picture, I think you'll see it.

4th gear works well too

So, I guess taking out a spark plug and jamming a large screw driver against the piston is a bad idea

BTW this is more removing the stuck crank pulley bolt rather than the pulley its self.

Some times getting the pulley off the end of the crank shaft is a hole nother thing!
