Abstract

Various embodiments include a method of displacing a turbomachine component from position in a first slot of a turbomachine spacer disk. The method can include detachably affixing a mounting member of a displacement apparatus to a second slot in the gas turbomachine spacer disk using an attachment device, rotating a displacement arm of the displacement apparatus until the displacement arm contacts the turbomachine component, and displacing the turbomachine component from the position within the first slot by linearly actuating the displacement arm with a linear actuator.

First claim

What is claimed is:

1. A method of displacing a turbomachine component from a position in a first slot of a turbomachine spacer disk, the method comprising:
detachably affixing a mounting member of a displacement apparatus to a second slot in the turbomachine spacer disk using an attachment device;
rotating a displacement arm of the displacement apparatus until the displacement arm contacts the turbomachine component; and
displacing the turbomachine component from the position within the first slot by linearly actuating the displacement arm with a linear actuator.

2. The method of claim 1 , wherein linearly actuating the displacement arm comprises actuating the displacement arm in a first axial direction.

3. The method of claim 2 , wherein the linear actuator actuates the displacement arm in the first axial direction a distance at least equal to an axial length of the second slot.

4. The method of claim 2 , wherein the first axial direction coincides with an axial direction of the first slot.

5. The method of claim 1 , wherein the linear actuator includes a double acting hydraulic ram, the method further comprising:
actuating the displacement arm in a second axial direction, opposite the first axial direction after displacing the turbomachine component.

6. The method of claim 1 , wherein the linear actuator and the mounting member are coupled to a body.

7. The method of claim 1 , wherein the displacement arm is coupled to the linear actuator.

8. The method of claim 1 , wherein the first slot is adjacent the second slot.

9. The method of claim 1 , wherein rotating the displacement arm of the displacement apparatus until the displacement arm contacts the turbomachine component includes contacting a contact material of the displacement arm against the component.

10. The method of claim 1 , wherein rotating the displacement arm of the displacement apparatus until the displacement arm contacts the turbomachine component includes rotating the displacement arm about the linear actuator from a first position to a second position, the first position radially offset from the second position relative to an axis of the linear actuator.
