Use a wrench to install the new rectifier, tightening it as much as possible without breaking the insulator, and add the new voltage regulator and brush holder. Next, screw in the diode, ensuring you match up the insulator with your mark. Then reinstall the stator ring. (If the stator is new, you may need to bend the terminals a bit to fit.) Finally, find the clock positions and bolt the front and rear halves of the case back together.
