Abstract

Examples of a removal tool for a two-piece guide bushing are provided. A specific example comprises a handle, a cap coupled to the handle, the cap comprising arced slots; and a raised boss coupled to the cap, the raised boss configured to fit over the stem guide of a two-piece guide bushing. The guide bushing removal tool may be coupled to a two-piece guide bushing and the guide bushing removal tool may be configured such that rotation of the handle releases the guide bushing center of the two-piece guide bushing.

First claim

What is claimed is:

1. A guide bushing removal tool comprising:
a handle,
a cap coupled to the handle, the cap comprising arced slots; and
a raised boss coupled to the cap, the raised boss configured to fit over the stem guide of a two-piece guide bushing, the raised boss comprises deformable grips.

2. The guide bushing removal tool of claim 1 , wherein the arced slots are configured to fit over the free ends of a spring clip of the two-piece guide bushing.

3. The guide bushing removal tool of claim 1 , wherein when the guide bushing removal tool is coupled to the two-piece guide bushing, the guide bushing removal tool is configured such that rotation of the handle releases the guide bushing center of the two-piece guide bushing.

4. The guide bushing removal tool of claim 1 , wherein the handle comprises a hexagonally shaped head.

5. The guide bushing removal tool of claim 1 , wherein the handle comprises a head and wherein the head comprises an insertion slot.

6. The guide bushing removal tool of claim 1 , wherein the handle and the cap are one continuous piece.

7. The guide bushing removal tool of claim 1 , wherein the cap and the raised boss are one continuous piece.

8. The guide bushing removal tool of claim 1 , wherein the cap comprises at least one installation slot.

9. The guide bushing removal tool of claim 1 , wherein the cap comprises a lip.

10. The guide bushing removal tool of claim 1 , wherein the deformable grips comprise wire springs.

11. The guide bushing removal tool of claim 1 , wherein the deformable grips comprise a steel alloy.

12. The guide bushing removal tool of claim 1 , wherein the handle comprises a steel alloy.

13. The guide bushing removal tool of claim 1 , wherein the cap comprises a steel alloy.

14. The guide bushing removal tool of claim 1 , wherein the raised boss comprises a steel alloy.

15. The guide bushing removal tool of claim 1 , wherein the handle extends away from the cap.

16. The guide bushing removal tool of claim 1 , wherein the handle comprises a handle bar having a T-shape.

17. The guide bushing removal tool of claim 1 , wherein the handle comprises a handle base adjustable in length.

18. The guide bushing removal tool of claim 8 , wherein the installation slot restricts rotational movement of a free end of a spring clip of the two-piece guide bushing.

19. The guide bushing removal tool of claim 1 , wherein the deformable grips comprise an elastomer.

20. The guide bushing removal tool of claim 1 , wherein the raised boss is coupled to the cap by welding, a threaded connection, or an adhesive.
