There are pulleys around that use a tapered collar to fasten onto a shaft at any point chosen by the installer but I seriously doubt that anyone would have fitted one to an engine.
In the first instance, if the pulley is that far from the normal position it is unlikely that the oil seal journal will reach to the seal and you would be pumping engine oil out of the front of the engine.
In the second instance, the crank pulley normally serves the function of clamping the crankshaft timing sprocket in position. Without this function it would not be long before the sprocket eats away the key and causes a major calamity inside the timing cover
Niether of these functions would be served by the type of pulley described above. Those taper-clamp types are normally used on accessory shafts or electric motors. I've never seen one used on an engine.
Having said all that, I can't offer any advice on why the pulley would be that far out of position. Can you get the pulley assembly off? The solution may then be plain to see.
