Abstract
A tool for removing a propeller from a drive shaft having a damaged shear pin. The tool has a plurality of fingers for engaging the blades of the propeller and an advancement member for leveraging against the distal end of the shaft. The advancement member leverages against the drive shaft to cause the tool to pull the propeller assembly from the drive shaft to facilitate the replacement of the damaged shear pin. The tool fingers engage and restrict the rotation of the propeller blades with respect to the tool as the advancement member is leveraged against the drive shaft.
Claims16
A tool for assisting the removal of a propeller having a propeller face and a plurality of blades from a rotatable drive shaft, comprising:
- a) a body member comprising an enlongated major surface having a configuration adapted to lie juxtaposed to said propeller face and a securing means extending substantially perpendicular from the elongated major surface, the body member having a central axis, the securing means coupled to said body member and adapted to engage the blades of the propeller and to prevent rotation of said propeller with respect to said body member;
- and
- b) advancement means disposed proximate said body member central axis and adapted to leverage against the drive shaft to cause said securing means to remove the propeller from the drive shaft.
A method using a tool to remove a propeller having a plurality of blades from a rotatable drive shaft, said tool comprising:
- a) an enlongated body member major surface having a securing means extending substantially perpendicular from the elongated body member major surface, the elongated body member having a central axis;
- b) securing means coupled to said elongated body member major surface adapted to engage the blades of the propeller and to prevent rotation of said propeller with respect to said elongated body member major surface;
- c) advancement means disposed proximate said central axis and adapted to leverage against the drive shaft to cause said securing means to remove the propeller from the drive shaft,
- comprising the steps of:
- disposing the tool about the propeller such that the securing means engages the propeller blades and restricts rotation of the elongated body member major surface with respect to the propeller;
- and
- advancing the advancement means against the drive shaft to apply leverage to cause the tool to remove the propeller from the drive shaft.
