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.
