Abstract

System for reducing friction during gas turbine engine assembly comprising a rear hub (230) having a conical web (236), a horizontal arm (234) coupled to the conical web (236) and a hub kickstand (232) coupled to the conical web (236). The conical web (236), horizontal arm (234), and hub kickstand (232) converge at a pivot point (235). The hub kickstand (232) is coupled to a tie shaft snap (212) of the tie shaft (210) via hub foot (233). The invention is based on the concept that in addition to applying a stretch force (204) to the tie shaft (210) a compressive force (206) is applied to the horizontal arm (234). Thus, pivot point (235) is moved from a first position (235A) to a second position (235B). Thus, hub foot (233) is lifted/ detached from tie shaft snap (212) substantially reducing frictional force between rear hub (230) and tie shaft (210).
