Hi John, Use your "key spacer" to rotate the pin (under the punching to prevent scoring) and visually compare the angle of the tool to the front rail at the point before the pin turns to the left and at the point where it will turn to the right. Average the angle to get the pin turned right (and left) side to. This should be done before reinstalling the keys so that is one problem you need not have to deal with. Next polish the keys (I prefer FLITZ) and lubricate the pins AND the bushings with a dry teflon spray lubricant. Install one key at a time and carefully fit the bushings AND the bottom of the key before going on to the next. When this is all done you have a perfectly functioning set of keys ready for leveling.
