So I recently received a car from a lady I do yard work ford it s 2002 ford taurus dohc 3.0. Ling story short through a fuel pump in her and I drove it home. I'm needing to replace the crank seal but I cannot get the extended harmonic balancer off to save my life. I know its reverse threaded so I'm not turning it the wrong way. I've tried wedging it with a long breaker bar and turning the motor over. Ive tried an ELECTRIC AS IN PLUG IN impact wrench to no avail (makes about 230ftlbs of torque should've been plenty powerful) so I returned that and bought a compressor and a impact gun that makes 560ftlbs of torque. Is there a trick to removing this EXTENDED harmonic balancer? Or will making to swap to air get it done? I've only seen one other video on youtube with the same style harmonic and he ended up having to cut the damn thing off of there then cut the extended shaft off then was able to impact it off without an issue. But the guy literally cut it in 2 with a cutting wheel so he had to replace that whole assembly. I'm trying to find a way without destroying the harmonic?
