Actually it's a very smart thing to set a time when an engine reaches a given mileage and start taking things apart. In the aircraft world these items are called time change items. When they reach a certain hour flight time they are automatically changed. Also the aircraft is involved in Phase dock where deer crab goes in the face. And all the components the large components are taken apart and inspected for corrosion and cracks and so on. Also do a spin test on all the bearings such as idle tensioner. Water pump. I wouldn't use the test for the alternator because rotor has mass behind it so it's really hard to tell if the bearing is dry or not. But if the tensioner rotates more than three-quarters or just spins freely in the bearings are dry there's no grease dragging the ball bearings.
Point taken...but in the aircraft world IF something critical fails you don't get to call a tow truck. Hence the stricter need for maintenance/inspections.
