Abstract

A method of installing a seal in a bore of a component includes, among other things, slidably orienting the component in a support fixture. The method includes securing a base plate to the component. The method includes arranging the seal onto a pusher. The method also includes inserting the pusher into a hole in the base plate. The method further includes installing a hub onto the base plate and over the pusher. The method further includes rotating a rod relative to the hub to advance the pusher and seat the seal in the bore.

First claim

What is claimed is:

1. A method of installing a seal in a bore of a component, comprising:
providing a tool case to reveal a support fixture with a shaped groove configured to receive a component flange, wherein the shaped groove extends longitudinally between facing lateral surfaces;
slidably orienting the component in the shaped groove while the component is longitudinally retained by the facing lateral surfaces;
securing a base plate to the component;
arranging the seal onto a pusher;
inserting the pusher into a hole in the base plate;
installing a hub onto the base plate and over the pusher; and
rotating a rod relative to the hub to advance the pusher and seat the seal in the bore.

2. The method of claim 1 , wherein the installing step includes threading the hub onto a collar of the base plate and receiving an end of the rod in a pocket of the pusher in a slip fit relationship.

3. The method of claim 1 , comprising the step of opening a tool case and placing the component in the support fixture, and the orienting step includes rotating the component about its axis to position the bore generally vertically.

4. The method of claim 3 , wherein the component includes a perimeter flange, and the orienting step includes sliding the flange within complementarily shaped groove in the support fixture.

5. The method of claim 1 , wherein the securing step includes abutting a boss of the component with the base plate, wherein the bore is arranged in the boss, and comprising a step of clamping the base plate to the boss by securing bolts to the base plate.

6. The method of claim 5 , wherein the clamping step includes inserting the bolts from a side opposite the boss at an interior of the component.

7. The method of claim 5 , wherein the securing step includes providing a window in the base plate that leaves the seal visible through the window subsequent to the inserting step.

8. The method of claim 7 , comprising the step of observing longitudinal movement of the seal past the window toward the bore.

9. The method of claim 1 , wherein the pusher includes first and second diameter portions that form a first shoulder, and the arranging step includes sliding the seal onto the first diameter portion and into abutment with the first shoulder.

10. The method of claim 9 , wherein the pusher includes a third diameter portion forming a second shoulder with the second diameter portion, and the hole includes a stop that abuts the second shoulder in a fully installed seal position.

11. The method of claim 10 , wherein the pusher includes first and second pusher portions, the first and second diameter portions provided on the first pusher portion, and the third diameter portion provided on the second pusher portion, the first and second pusher portions secured to one another by a fastener.

12. The method of claim 10 , wherein the rotating step slides the first diameter portion into the bore in a slip fit relationship.

13. The method of claim 10 , wherein the rotating step includes threadingly rotating the rod relative to the hub and tightening the rod until the second shoulder contacts the stop.
