Engine component removal tool
A removal tool configured for removing an insertable engine component from an engine assembly. In the removal tool may include a coupling device, a drive member, and a lifting member attached to a main shaft. The coupling device is mounted onto a retainer securing an engine component, and the lifting member is positioned against the underside of a flange of the engine component. A rotational force applied against the drive member is transferred to the coupling device and causes the retainer to be unscrewed. As the retainer is unscrewed, this causes a lifting force from the retainer pushing against the coupling device, which causes the lifting member to be pushed upward, and further causing the engine component to be pushed upward and away from the engine assembly. This facilitates removal of the engine component concurrently with the removal of the retainer (e.g., in a single operation).
1. A removal tool for removing an insertable engine component from a slot of an engine frame, comprising:
a main shaft having a distal end, a proximate end, and an intermediate section;
a coupling device coupled to the distal end of the main shaft, wherein the coupling device is configured to be coupled to a retaining component securing the insertable engine component to the engine frame;
a drive member coupled to the proximal end of the main shaft, wherein the drive member is configured to receive a rotational force;
a lifting member directly attached to the intermediate section of the main shaft, wherein the lifting member is configured to be releasably coupled to at least a portion of the insertable engine component, wherein the main shaft is configured to transfer the rotational force from the drive member to the coupling device to cause the retaining component to rotate about a longitudinal axis of the main shaft and to move in a vertical direction applying an upward force against the main shaft; and
a detent member in direct contact with the intermediate section and configured to:
resist, via the direct contact with the intermediate section, a sliding movement of the lifting member in a downward direction along the longitudinal axis of the main shaft; and
receive the upward force from the main shaft and to move in the upward direction in response to the upward force to lift the insertable engine component out of the engine frame, wherein the main shaft, the lifting member, and the detent member concurrently move in the vertical direction in response to the upward force applied against the main shaft without the main shaft passing through the detent member.

5. The removal tool of claim 4 , wherein the upper section includes the drive member and a distal end configured to be coupled to a proximate end of the lower section.
6. The removal tool of claim 4 , wherein the lower section includes the coupling device and a proximal end configured to be coupled to a distal end of the upper section.
7. The removal tool of claim 1 , wherein the lifting member includes an opening configured to receive the main shaft and configured to enable the lifting member to slide along a longitudinal axis of the main shaft and to freely rotate about the longitudinal axis of the main shaft.
8. The removal tool of claim 1 , wherein the retaining component is loosened and separated from the bore concurrently with the lifting of the insertable engine component out of the slot of the engine frame in response to the rotational force applied to the drive member, representing a single-step operation to remove the retaining component and the insertable engine component.
9. A vehicle engine component removal tool, comprising:
a main shaft having a first and second end;
a coupling device coupled to a first end of the main shaft, wherein the coupling device is configured to releasably engage a retaining component operably coupled to an engine frame;
a lifting member directly attached to a portion of the main shaft, wherein the lifting member is configured to receive at least a portion of an insertable engine component;
a drive member coupled to the proximal end of the main shaft, wherein the drive member is configured to receive a rotational force to withdraw the retaining component from the engine frame while withdrawing the insertable engine component from an engine, by operation of an upward force applied against the main shaft by the retaining component; and
a detent member in direct contact with an intermediate section and configured to:
resist a sliding movement of the lifting member in a downward direction along the longitudinal axis of the main shaft; and
receive the upward force from the main shaft and to move in the upward direction in response to the upward force to withdraw the insertable engine component from the engine, wherein the main shaft, the lifting member, and the detent member concurrently move in the vertical direction in response to the upward force applied against the main shaft without the main shaft passing through the detent member.
