The brush holders and brushes needing to be held back against their springs was an issue when we were putting the motor back together. It really took two of us (four hands) to do it, so it wasn't a one person job. The way the factory quickly assembled these I'm told was similar to how many electronic devices come today with batteries pre-installed. They have a pull-tab that you yank out in order to allow electrical connection. So the new brushes would be assembled in their holders pushing back the springs with some kind of tape or string retracting them. Once the holder was in position, you could yank out the tensioner, allowing the brushes to contact the commutator. But when you're rebuilding the motor, you have to do that manually and it's pain.
