ABSTRACT:
A method and apparatus for removing a propeller hub secured by a nut to a tapered drive shaft. A puller abutment is fixed to the hub in position to engage the nut and prevent axial movement of the nut relative to the hub. Rotation of the nut against the axially immovable abutment results in axial movement of the hub, nut and abutment relative to the shaft, separating the hub from the shaft. Continued rotation of the nut separates the hub and nut from the shaft.
