Abstract
A method of removing a locking ring from a component includes welding at least one sacrificial tab to the locking ring while the locking ring is within a bore of a component and axially forcing the locking ring from the bore along the axis.
Claims15
A method of removing hardware from a bore in a component, comprising:
- welding at least one sacrificial tab to the hardware while the hardware is within the bore, the bore defined along an axis;
- and
- axially forcing, by using at least the at least one sacrificial tab, the hardware from the bore along the axis.
A method of removing a locking ring which axially retains a stub within a bore in a component, comprising:
- locating an insulator about a stud retained by the locking ring;
- locating a first sacrificial tab adjacent the insulator in contact with the locking ring;
- locating a second sacrificial tab adjacent the insulator in contact with the locking ring;
- locating a first electrical contact in contact with the first sacrificial tab;
- locating a second electrical contact in contact with the second sacrificial tab;
- retaining the first electrical contact in contact with the first sacrificial tab and the second electrical contact in contact with the second sacrificial tab about the insulator with a retaining sleeve;
- passing an electrical current through the first and the second electrical contact to weld the first sacrificial tab and the second sacrificial tab to the locking ring while the locking ring is within the bore of the component, the bore defined along an axis;
- and
- axially forcing, by using at least the first and second sacrificial tabs, the locking ring from the bore along the axis.
6 more elements
A tool assembly for removing hardware from a bore in a component, comprising:
- a set of contacts which form at least a portion of an impact hammer along an axis and which are configured to contact the hardware in the bore;
- and
- a power source in communication with said set of contacts to weld said set of contacts to the hardware.
