There was actually a bulletin about the loose pulley nut causing the keyway to elongate.
20 years ago I bought a reasonably new van from the BSM of the artillery battery was attached to. It had a knocking engine. I negotiated the price based on that. Went to pull the engine and yep...loose pulley. The pair of artillery guys he had do some engine work did not torque the nut. It was still early enough in the wear that I was able to cut a new keyway in the pulley and the van continued on for another decade.
