Early this morning I started my car and the Crankshaft Pulley in my engine got dislodged/disconnected from the engine. Not knowing that it was dislodged, I drove it for about 10 meters back to its parking place. When I checked the pulley I saw that the thread in the center hole are already worn out. Even the bolt's thread are also worn out and needs to be replaced.
What could possibly be the damage to my engine and how can this be fixed? Apart from pulley and bolt, are there any other parts that I need to check and replace?
Thanks in advance...
