Abstract

A method of installing a seal in a bore of a component includes securing a base plate to a 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:
securing a base plate to the component, wherein the securing step includes abutting a boss of the component with the base plate, the bore is arranged in the boss;
clamping the base plate to the boss by securing bolts to the base plate;
arranging the seal onto a pusher;
inserting the pusher into a hole in the base plate, 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;
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 clamping step includes inserting the bolts from a side opposite the boss at an interior of the component.

3. The method of claim 1 , comprising the step of observing longitudinal movement of the seal past the window toward the bore.

4. A method of installing a seal in a bore of a component, comprising:
securing a base plate to the component;
arranging the seal onto a pusher, wherein the pusher includes first and second diameter portions that form a first shoulder, the arranging step includes sliding the seal onto the first diameter portion and into abutment with the first shoulder, wherein the pusher includes a third diameter portion forming a second shoulder with the second diameter portion;
inserting the pusher into a hole in the base plate, and the hole includes a stop that abuts the second shoulder in a fully installed seal position;
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.

5. The method of claim 4 , 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.

6. The method of claim 4 , wherein the rotating step slides the first diameter portion into the bore in a slip fit relationship.

7. The method of claim 4 , wherein the rotating step includes tightening the rod until the second shoulder contacts the stop.

8. A method of installing a seal in a bore of a component, comprising:
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, wherein the installing step includes threading the hub onto a collar of the base plate; and
rotating a rod relative to the hub to advance the pusher and seat the seal in the bore.

9. The method of claim 8 , wherein the installing step includes receiving an end of the rod in a pocket of the pusher in a slip fit relationship.

10. The method of claim 9 , wherein the rotating step includes threadingly rotating the rod relative to the hub.

11. A seal installation tool for installing a seal in a boss of a component having a bore, the tool comprising:
a base plate having a hole, the base plate having a window adjoining the hole, wherein the base plate is configured to be clamped and secured to the component with bolts such that the base plate is in abutment with the boss;
a pusher having first and second diameter portions that form a shoulder, the first diameter portion configured to carry the seal against the shoulder, wherein the seal is aligned with and visible through the window in an uninstalled seal position, the pusher arranged in the hole in a slip fit relationship;
a hub removeably secured to the base plate over the pusher; and
a rod threadingly received by the hub for relative rotation thereto, an end of the rod cooperating with the pusher, the rod configured to longitudinally slide the pusher relative to the base plate and seat the seal in the bore.

12. The tool of claim 11 , wherein the base plate includes threaded holes configured to receive the bolts that clamp the base plate to the component having the bore receiving the seal.

13. The tool of claim 11 , 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.

14. The tool of claim 11 , 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.

15. The tool of claim 14 , wherein the first and second pusher portions are different materials.

16. The tool of claim 11 , wherein the pusher includes a pocket that receives an end of the rod in a slip fit relationship.

17. The tool of claim 11 , wherein base plate includes a collar, and the hub is threadingly secured to the collar.
