Recently I was told I would need a chain wrench in order to remove my crankshaft pulley along with the vibration damper. Is this true or is there a way around this?

What engine and trans? Generally a large bolt will just turn the engine - air tools defeat that, standard trans in gear or whatever to hold damper in place while removing the large bolt,

Ive had it to where the damper wasnt moving at all. and used breaker bar. the socket snapped before anything. Then I used an impact wrench only at 130 psi but I thought it should be enough. Should I try a large compressor?

Try a socket made for impact wrench! What is this vehicle? Do you know that threads are standard or could this be some left handed job? Most are regular. You'll be in deep sneaker if that bolt breaks!

Maybe not. You have two threads going on this - what is this vehicle or just stick with one of them now as it's too late to keep up with both,

I don't know for certain about anything, but this should be standard counter clockwise is removal NOT LEFT threaded. Just in general, watch out for fasteners on anything that turns in unknown cases.
Notes from the past and present: Left hand threads are found on MANY older cars left side wheel lugs - some foriegn cars used left hand threads on axle bearing nuts (VW bug orig version) ---- fans for heater, cooling system radiator fans and who knows with some of the cars now with names I can't even recall sold to the US and some that never were which I would know little about.
Seems most "American" stuff avoids using left handed threaded anything unless absolutely necessary and instead on pulleys and things that would matter used pressed on things and avoid that altogether as it was an era of confusion back when....
