  3. Place distributor in Axle Bearing Remover (T75L-1165-B). Press off gear using arbor press and Pinion Bearing Cone Remover (D79L-4621-A). Using emery cloth, remove burrs from distributor shaft. Remove shaft from distributor assembly.
  4. Remove thrust washer from distributor and save for installation. Remove screw and octane rod assembly. Save octane rod and screw for installation. Remove stator assembly screws and stator.
