It depends on what you're trying to accomplish, more info please.
you just need a puller to take it off, it's not a special puller.
AKA, crank pulley damper, crankshaft damper, torsional damper, or vibration damper.
The "balancer" mounted to the front of the crankshaft is also called a vibration damper.
No Because it is made out of rubber
How do I get to the crankshaft of a 1991 camero RS
The crankshaft damper is behind the crankshaft pulley.
The vibration damper pulley and the crankshaft pulley are pressed together with a rubber sleeve. They are held onto the crank by a key and keyway. I've never had to use a puller. Usually when you take the bolt out of the crank it will just wiggle off. I've never had one on their that tight that it wouldn't come off just with my hands.
Drop the engine by removing the passenger motor mount
if it has a distributor, its in the distributor, if no distributor its at the front of the engine by the crankshaft damper
Yes.
You need to use a puller tool. The trick is not to pull against the stamped center of the damper that looks like a washer. You need to thread the crankshaft bolt out a bit and push against the bolt head.
The crankshaft position sensor is located at the front of the engine close to the crankshaft damper
