Hi Mary Ferrulli Barker,

    To remove the armature in a Foredom R motor, remove sheath and
    shaft,  remove motor brush caps and brushes, remove the two screws
    on the motor front  end (the end that the shaft and sheath were
    attached), pull motor front end off  then remove the armature. To
    install new armature be careful to not touch the  commutator (smooth
    copper part) and if you do you can clean finger dirt off with 
    alcohol and a lint free cloth. Add a drop of oil to the shaft ends
    near the spacers ONLY if it is the older sleeve bearing version, the
    newer ball  bearing version will have new bearings and does not
    require oil. Install  armature and reassemble the motor. Install NEW
    brushes. Run the motor at low  speed for a few minutes to "seat the
    new brushes in". Call us if you have  questions.
