Position the outer drive assembly on blocks in a suitable press with the shaft facing upward

Remove the snap ring from its groove in the shaft

Press the shaft downward until the outer bearing disengages from the shaft

Remove the outer ring assembly with shaft and inner bearing attached, wave spring and outer bearing

Remove the inner bearing from the shaft with a suitable gear puller

Apply a light oil to the shaft and press the new inner bearing into the shaft. The new bearing inner race should be flush with the outer ring. Be careful to avoid disrupting the shaft position relative to the outer ring

Insert the wave spring into the inner bearing counter-bore of the magnet housing /bearing housing

Insert the outer ring/shaft/inner bearing assembly into the magnet housing/bearing housing

Press the outer bearing onto the shaft until the distance from the end of the shaft to the face of the bearing

Warning: This procedure requires trained personnel with PPE!
