All the pistons and rods are out of the engine?
That makes things a lot easier.
The crank is just stuck now because you had caps off and torqued on it.
Its wedged on the thrust I suppose. See if you can turn it back the other way it should fall back into place.
When you get the caps back on there use a 2x4 block of wood between the counterweight and pan rail to keep it from rotating when youre removing the damper.
Use some kind of washer on end of crank snout so it doent get damaged and make sure threads on puller are oiled up good.
