on the Chrysler engine (420a) you do need a puller and installer to deal with the crankshaft dampener pulley.
if its sohc it doesnt have , if its dohc its behind the lower damper i think
AKA, crank pulley damper, crankshaft damper, torsional damper, or vibration damper.
you just need a puller to take it off, it's not a special puller.
The "balancer" mounted to the front of the crankshaft is also called a vibration damper.
No Because it is made out of rubber
The crankshaft damper is behind the crankshaft pulley.
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
You need a special harmonic damper puller. It's a variant of a basic 3-jaw puller that it made stronger so that it wont break.
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
