  • Engine component removal tool
    Patent number: 12269149
    Abstract: 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).
