Probably some "mechanic" tightening them by "feel" instead of using a torque wrench.
Maybe not- if they were installed 30 years ago with the tapers cleaned of any grease at the specified 300 to 400 inch-pounds of torque... they won't come off without a bunch of force. I've resorted to hammering on the handle of the crank puller a few times.
