Next, remove the collet from the shaft. Using a rag, or a thick glove, tightly hold on to one end of the armature shaft, as you use an impact wrench to remove the chuck. Use a rubber mallet to tap the armature free from the housing. For units with bearings mounted in the housing – opposed to on the armature shaft – use retaining ring pliers to remove the ring holding the bearing in place, inside the housing.
Next, use a socket that only makes contact with the inner race of the bearing and tap it free from the housing. Now, flip the housing over and insert the new bearing in place and use a socket that only makes contact with the outer race. Tap the bearing in place.
Reinstall the retaining ring. Install the armature back in the housing and tap in place with a rubber mallet. To replace the bottom bearing, you can leave the armature in the housing. Use a bearing puller to remove the bearing. Apply a small amount of grease to the shaft and install the bearing on the shaft. Place a socket on the bearing that only makes contact with the inner race to avoid damage to the bearing. Tap the bearing into place with a mallet.
Reinstall the chuck with the impact wrench, as you hold onto the opposite end. Reinstall the collet. Rejoin the two halves of the motor housing. Make sure the reference marks are lined up. Reinstall the tension on the brushes and reattach the motor cover. Reattach the base.
Install a new fan onto the shaft then reinstall the clip to secure it in place. Install the bearing with a press or put the shaft in a bench vice with the soft jaws attached, to avoid damage to the armature. Use a socket big enough that only makes contact with the inner race of the bearing and tap it into place with a hammer. Put the wave washer back in. Reinsert the armature in the housing and use a mallet to tap it in place. Reinstall the chuck with the impact wrench as you hold on to the opposite end. Rejoin the two halves of the motor housing, making sure the reference marks are lined up. Reinstall the tension on the brushes and reattach the motor cover. Reattach the base.
