STEP 5  By now all pivot points should be moving freely    So now we will turn to the other side of the unit some steppers dont need to be pulled apart to be cleaned. But this one i find easier if apart.  If its a stepper with 2 coils step it back to the start position and mark the Wipers or disk with a mark on the frame.
