Abstract

A tool for seating a wear liner into a first groove of a fan case of a gas turbine engine includes a body, a handle, and a first guide foot. The body includes a first end and a second end. The handle is connected to and extends from the body. The first guide foot is connected to and extends from the first end of the body. The first guide foot includes a first end connected to the body and a second end opposite from the first end of the first guide foot. The second end of the first guide foot is rounded and includes a chamfered portion.

First claim

The invention claimed is:

1. A tool for seating a wear liner into a first groove of a fan case of a gas turbine engine, the tool comprising:
a body with a first end and a second end, the first end and second end defining a longitudinal body axis;
a handle connected to and extending from the body; and
a first guide foot connected to and extending from the first end of the body, the first guide foot having a first end connected to the body and a second end extending radially away, with respect to the longitudinal body axis, from the first end of the first guide foot;
wherein the second end of the first guide foot is defined by parallel, opposing first and second sides; and
wherein the second end of the first guide foot has a rounded edge at a radially outermost extent that is rounded along an axial cross-section, with respect to the longitudinal body axis.

2. The tool of claim 1 , further comprising:
a first face extending along a first side of the body; and
a second face extending along a second side of the body, wherein the second face is on an opposite side of the body from the first face, wherein the first and second faces are flat.

3. The tool of claim 1 , wherein a shape of the rounded edge of the second end of the first guide foot through the axial cross-section follows a first curvature that is configured to match a curvature of the first groove of the fan case.

4. The tool of claim 3 , wherein a longitudinal handle axis is perpendicular to the first curvature of the first guide foot.

5. The tool of claim 1 , further comprising:
a second guide foot connected to and extending from the first end of the body in a radial direction opposite that of the first guide foot;
wherein the second guide foot is configured to insert into a second groove of the fan case.

6. The tool of claim 5 , wherein:
the first guide foot extends along a first plane;
the second guide foot extends along a second plane; and
the first plane and the second plane are parallel and nonidentical.

7. The tool of claim 1 , wherein the first guide foot includes a first thickness, wherein the first thickness of the first guide foot is less than a width of the first groove of the fan case.
