There may not be diagrams available.  The idea of fiber washers/spacers is to center up the rotor laminations
to the stator laminations.  Put washers on the back end  of the rotor to do this.  Eyeball the rotor placement by
looking through the back vent holes and compare with the front.  Most efficient magnetic transfer occurs when
rotor is centered.  Add washers to the front of rotor shaft to give about 1/16" front to back play when putting
front bell cover back on.  Keep in mind that fan blade running pushes the rotor towards the back of the motor
from air pressure.
Happy fanning!
