Replacing Crankshaft Pulley Harmonic Balancer on 1991 Saab 900 Turbo?

If you have done this than what I'm really trying to figure out is how to get the socket in that 1 inch space and replace the pulley without removing the engine. Or any good way you may have done it.

Need a special tool that does this job. WIthout it you will not be able to loosen and tighten the bolt to 150-160 ft-lb. There is also a engine locking tool to keep the engine from turning. Check with Snap on for the tools. It is not cheap, try about $100 or more. Remember to use a new pulley and change all the seals including the oil pump seals, when you replace this pulley.

I've seen a car that the owner put a whole in the fire wall to be able to use impact socket. To lock the engine use the flywheel area.

Auto trans: use a 16-17 mm socket on torque converter bolt.

Manual trans: use a large screwdriver from underneath access hole and lock the flywheel tooth.
