Remove the screw you can see from the front and then rock the stepper motor down which will loosen the side bolt and allow access. Do the same in reverse and rocking the stepper back up will tighten the side bolt if done just right.

That's pretty high. The unit will need to be torn down to access the brushes and slip rings and the slip rings should be cleaned and tested at the rotor.
