How does this do, I didn't feel up to tripping a good dynamo just to photograph it?
The stepped and swaged washers are stepped towards the bearing inner race and clear of the balls and outer race.
The outer race should be clamped between the end cover and drive end shield, whilst the inner race is clamped by the drive gear, spacer, swaged washer and stepped washer such that the only end float is provided by the bearing. Now most dynamos I've dismantled have an alarming amount of end float and the bearing has not been trapped with wear of the end cover or a worn short spacer. So I adjust the end cover so that the bearing outer race is clamped and/or I make a new spacer to ensure the bearing inner race is trapped.
