No! you should use a chain wrench to hold the pulley from turning,lefty loosy, righty tighty!
To remove a crank shaft pulley you need to first jack up the car. Next, remove the bold holding the crack shaft pulley in place and remove the unit. Reverse direction to put the new crank shaft pulley on your car.
This is normally done with an impact wrench... a type of air tool. The impact wrench can tighten the pulley without turning the crank. You can probably rent a compressor and an impact wrench with sockets from your local tool rental company.
On most newer cars, the crank pulley is one piece with the harmonic balancer.... Remove it with a harmonic balancer puller.
Directly below the alternator on the block.
No. They are a normal Righ-Hand thread: 'righty tighty/lefty loosy' :-) The Crank pulley IS very tight (hopefully) upwards of 120/ft-lbs is normal torque. Check http://www.ultimatesubaru.org/forum for info on 'how to ' remove. TD
12mm /19mm
remove all belts,tensioners etc, remove pulley bolt, use HARMONIC BALENCER PULLEY to remove - DO NOT USE NORMAL PULLEY REMOVER - must be pulled from center of pulley not from outer edge
The crank position sensor is behind the crank pulley. You need to remove the pulley, remove the plastic shield and remove two of the lower front cover bolts. Then you can remove the crank sensor. This proceedure is more complicated than it sounds. Check out the following website for a cam install and scroll down to where it talks about removing the harmonic balancer (crank pulley) http://www.mccgp.com/upgrades/caminstall/caminstall.php Hope this helps.

You have to get a pulley puller of the appropriate size. Without a pulley you have no chance safely to remove it. Be careful do not deform the pulley it's not that hard as you can think.
Loosen the 18mm bolt about 4 or 5 mm and give the bolt a good wack and the pulley should pop. Then remove the bolt and pulley.
There is a large metric bolt right (17 or 18mm) in the center of the main crank pulley. Immobilize the crank using a vise-grip equiped with a locking chain. Wrap an old fan belt (cut-to-size) around the crank and protect the serpentine gooves of the crank pulley, then wrap the vise chain and clamp onto the crank. Use a good breaker bar, or impact hammer to break the bolt torque free counter-clockwise. Note: Don't remove the four 10mm bolts on the crank pulley. The whole thing comes off as one assemble piece.
