Abstract:
1. A method of adjusting the axial length of a shaft assembly for a gas turbine engine comprising: providing a first shaft rotatable about a central axis and having a diametrically outer surface and a diametrically inner surface with respect to said central axis, said first shaft including a radial step extending radially inwardly from said diametrically outer surface to a diametrically intermediate surface located radially between said diametrically outer surface and said diametrically inner surface, said radial step including an axially facing stop surface with a multiple of slots therethrough and an additional radial step extending radially inwardly from said diametrically intermediate surface toward said diametrically inner surface; mounting a locked spacer including a multiple of key tabs to the first shaft such that the multiple of key tabs mate with the multiple of slots, said locked spacer including an annular body having an axially facing land that abuts said additional radial step; and mounting a bearing to abut the locked spacer.
