Abstract

A tool system to install an interference fit component within a bore of a component, includes a guide bushing that at least partially fits within a bore of a component. A drive screw is of a length to extend through the guide bushing and the bore. A threaded insert is receivable at least partially within the bore, the threaded insert receivable at least partially within the interference fit component.

Claims (13)

1. A method for installing an interference fit component within a bore of a component, comprising:

locating an interference fit component at least partially onto a threaded insert;

locating a drive screw though a bore of the component, the drive screw defines an axis of rotation;

threading the drive screw into the threaded insert; and

rotating the drive screw about the axis of rotation, rotation of the drive screw pulling the threaded insert and the interference fit component into the bore.

2. The method as recited in claim 1 , wherein locating the interference fit component at least partially onto the threaded insert comprises abutting the interference fit component onto the threaded insert to abut a flange of the threaded insert.

3. The method as recited in claim 2 , wherein the flange is of a diameter greater than a diameter of the bore to stop against the component.

4. The method as recited in claim 2 , wherein the flange is of a diameter less than a diameter of the bore to drive the threaded insert out of the bore.

5. The method as recited in claim 1 , further comprising locating the interference fit component and the threaded insert within an installation mandrel.

6. The method as recited in claim 5 , further comprising holding the installation mandrel while rotating the drive screw.

7. The method as recited in claim 1 , wherein rotating the drive screw comprises hydro-pneumatically rotating the drive screw.

8. The method as recited in claim 1 , further comprising guiding the drive screw with a guide bushing that is at least partially receivable into the bore.

9. The method of claim 1 , wherein the step of locating the interference fit component at least partially onto a threaded insert further comprises locating the interference fit component on the threaded insert at one side of the component, and wherein the threading step comprises threading the drive screw into the threaded insert from the other side of the component.
