=== Installation and inspection === * Install your new bearing, but before you do, get a SMALL sharp punch and carefully put a dimple in the race each 1/3 rd the way around. One may use a dab (small dab) of epoxy to accomplish locking the bearing race. This will prevent the race from spinning in the case. It will be a tiny bit harder to put the cases back together, you might have to tap the halves with a rubber mallet. * Install the bushing (if applicable). Lubricate the bushing as required. * Where the brushes are, at the rear end bell, there should be a small hole that goes through to them. Insert a #40 drill bit or heavy paper clip with the brushes fully compressed into their holder. This will hold them off the slip rings while you insert the rotor into the end bell. Remember to remove the paper clip or drill before reinstalling the battery or a short could occur while removing the drill or paper clip. * Before reassembling the end bells to the body, inspect the stator windings. You are looking to make sure there is no worn insulating paint, aka [http://www.glyptal.com/ "Glyptal"]. Also, where the windings terminate, check that there is no melted or splattered solder, and no cracked solder joints. If needed, ohcheck the resistance with an ohm meter, but these usually last practically forever. * Align the witness mark you scribed into the body during dis-assembly, install the end bells to the body and properly 'clock' it for your application. Be sure the end bells are straight, and (if needed) gently tap the bearing half end-bell with a mallet. Secure with the bolts. * Lastly, spin it up by hand, in both directions, and ensure it spins free and quiet. Inspect the front fan blade for damage, and reinstall on the car. * Check your wiring to assure correctness and reconnect the battery. Start the car and using a digital voltmeter check the voltage at the battery terminals. It should be about 13.6 - 14.0 volts with headlights on. [[Image:image03.jpg]]
