Abstract
A pulley pulling device for removing a harmonic damper pulley having at least two spoke portions from a crankshaft comprises a hub including at least two clevis portions. A plurality of legs are pivotably connected to respective ones of the clevis portions, with the legs each including a body portion and a foot portion protruding laterally therefrom. The body and foot portions are contoured and oriented relative to each other such that the foot portion is adapted to engage a corresponding one of the spoke portions and to selectively pivot relative thereto as achieves optimized contact therebetween.

A pulley pulling device for removing a harmonic damper pulley from a crankshaft, the harmonic damper pulley having at least two spoke portions, the device comprising:
- a hub including at least two clevis portions, the hub being disposed about a central axis;
- and
- a plurality of legs pivotably connected to respective ones of the clevis portions, the legs each including a body portion and a foot portion protruding from the body portion, the body portion having a first face facing away from the central axis, a second face opposite the first face and facing toward the central axis, and a side surface extending between the first and second faces, the foot portion extending from the side surface;
- wherein the body and foot portions are contoured and oriented relative to each other such that the foot portion is adapted to engage a corresponding one of the spoke portions and to selectively pivot relative thereto as achieves optimized contact therebetween.
A pulley pulling device for removing a harmonic damper pulley from a crankshaft, the harmonic damper pulley having at least two spoke portions, the device comprising:
- a hub including at least two clevis portions, the hub being disposed about a central axis;
- a shaft coupled to the hub such that the hub is selectively translatable relative to the shaft;
- and
- a plurality of legs pivotably connected to respective ones of the clevis portions, the legs each including a body portion and a foot portion protruding from the body portion, the body portion having a first face facing away from the central axis, a second face opposite the first face and facing toward the central axis, and a side surface extending between the first and second faces, the foot portion extending from the side surface, each leg being pivotal relative to the hub between a first position and a second position, the foot portion of the leg moving toward the shaft as the leg transitions from the first position toward the second position;
- wherein the body and foot portions are contoured and oriented relative to each other such that the foot portion is adapted to engage a corresponding one of the spoke portions.
