ABSTRACT:
Apparatus is disclosed to remove a propeller force fit upon a tapered shaft having screw threads projecting from the propeller hub. A cylindrical nut with an inner flange is screwed on the threads. The flange provides a stop located a short distance from the propeller hub thereby limiting movement of the propeller down the tapered shaft at the instant it is broken free. A cylindrical jack is placed about the nut and adjacent an outermost puller plate which is stud bolted to the propeller hub. Thus, the jack can move the plate in a direction pulling said propeller down the tapered shaft until it contacts the stop.
