The oscillator collar is broken and missing the pin,you will need a new one and the adjusting pin. There is not a spring on that model, the later fans had the spring.

The first picture is a nut that hold the rotor in, probably going to need a new leather washer. That one looks bad. The second picture are shims which centers the motor, keep those, you will need those to center the motor. NP 196? Production model?

CCW to remove the nut from the end of the rotor shaft.  My only guess on the cut rods is to stop some vibration noise??  Seating and aligning the stator in the housing would be accomplished using the four threaded rods.  I lock two hex nuts on each rod and tighten them alternately, using a feeler gauge as I do to center the rotor in the stator.

My 71666 has the same motor tag prefix of "N".  From info compiled by Bill Voight and others, the date of your fan would be circa 1924-1926.  Yours has the cage badge that preceded the Pyramid badge that appeared circa 1927.  Yours probably has the cheap looking and very low "screen door" handle that has a round base on each end where it attaches to the motor.

The "cut rods" are for centering the rotor in the stator. Also the small rod coming out of the very center is for driving the oscillator. Before you try and remove the large nut it sticks out of I would remove the oscillator box off the back of the fan and get that rod out of your way. Also it removes counter clockwise.

The brass shims are for centering the motor, the threaded rods just hold the motor to the housing.
