I understand what you’re tying to explain.
So that we are 100% totally clear on what we’re talking about, there are two pulleys.
The pulley on the OUTSIDE of the engine, aka harmonic balancer. You can see this by looking at the bottom front of the engine. It turns the drive belts (alternator, water pump, power steering, air conditioning).
The pulley on the INSIDE of the engine, aka crankshaft gear pulley, is behind the harmonic balancer and drives the cam belt and you cannot see it unless you remove the harmonic balancer.
If the pulley on the inside is damaged, it is removable and replaceable for a couple of hundred dollars. It should not have done any damage to the crankshaft.
That’s why it would be ideal to see pictures showing where in fact the actual damage is
