Beschreibung
Zusammenfassung:	An assembly (20) includes a hydrostatic non-contact seal device (32) having a plurality of seal shoes (76) arranged about an axial centerline (22) in an annular array. The assembly (20) also includes a seal base (74) and a plurality of spring elements (78). The seal base (74) circumscribes the annular array of the seal shoes (76). A threaded base aperture (84) extends axially through the seal base (74). Each of the spring elements (78) is radially between and connects a respective one of the seal shoes (76) with the seal base (74). The spring elements (78) are formed integral with the seal base (74) and the seal shoes (76) as a unitary body. A method includes providing a tool (116) and mating a threaded shaft (118) of the tool (116) with the threaded base aperture (84), and using the tool (116) to remove the hydrostatic non-contact seal device (32).
