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 seal installation tool set comprising: a tool case having a support fixture provided by a fixed, non-adjustable shaped groove configured to receive a flange of a component with the support fixture remaining inside the tool case, wherein the shaped groove extends longitudinally between facing lateral surfaces, and the flange is configured to be in the shaped groove while the flange is longitudinally retained by the facing lateral surfaces, and the shaped groove and the flange being of complimentary shape such that the component may be rotated with its flange moving within the shaped groove; a base plate having a hole, the base plate having a window adjoining the hole; a pusher having first and second diameter portions that form a shoulder, the first diameter portion configured to carry a seal against the shoulder, the pusher arranged in the hole in a slip fit relationship; a hub removably 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; wherein the component is subject to a seal installation procedure using the seal installation tool set.

2. The tool set of claim 1 , comprising a tool tray arranged in the tool case over the support fixture, the tool tray having cut-outs that removably hold the base plate and an assembly comprising the pusher, the hub and the rod.

3. The tool set of claim 1 , wherein the pusher includes a pocket that receives an end of the rod in a slip fit relationship.

4. The tool set of claim 1 , wherein the seal is aligned with the window in an uninstalled seal position.

5. The tool set of claim 1 , wherein the seal is aligned with and visible through the window in an uninstalled seal position.

6. The tool set of claim 1 , wherein the base plate includes threaded holes configured to receive bolts that clamp the base plate to the component having a bore receiving the seal.

7. The tool set of claim 6 , wherein base plate includes a collar, and the hub is threadingly secured to the collar.

8. The tool set of claim 1 , 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.

9. The tool set of claim 8 , 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, wherein the first and second pusher portions are different materials.

10. A seal installation tool set comprising: a tool case having a support fixture provided by a fixed, non-adjustable shaped groove configured to receive a flange of a component with the support fixture remaining inside the tool case, wherein the shaped groove extends longitudinally between facing lateral surfaces, and the flange is configured to be in the shaped groove while the flange is longitudinally retained by the facing lateral surfaces, and the shaped groove and the flange being of complimentary shape such that the component may be rotated with its flange moving within the shaped groove; a base plate having a hole, the base plate having a window adjoining the hole; a pusher having first and second diameter portions that form a shoulder, the first diameter portion configured to carry a 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 removably 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; wherein the component is subject to a seal installation procedure using the seal installation tool set.
