When you install the new fan it is best to place the fan on the shaft without the woodruf key in place to see how far it goes to fit tight. Make a mark on the shaft and then install the key and reinstall the fan. If you don't get to the mark the slot in the fan is too shallow or the keyway is too shallow. You need to correct this or the fan will also work loose. This is another problem with fan installation that we covered in the Model A Times.
