1) Put Armature through Yoke unit.
    Note 1. Yoke unit is not reversible when assembled to Armature.  Be sure to assemble so that the notch in Yoke unit is
    positioned on the drive-end of Armature as illustrated to left in Fig. 28.   If assembled wrong, Motor assembly cannot 
    be assembled to Housing L.
    Note 2.
