An assembly for use with a gas turbine engine includes a tie rod and a connector. The tie rod, which is for extending radially outwardly from a latitudinal axis of the gas turbine engine, has a hollow length having a longitudinal axis and a base having a width in parallel to the latitudinal axis. The base has a counterbore disposed therein and is wider than a width of the length. The connector, for attaching the base of the tie rod to a bearing assembly of the gas turbine engine, has a hollow body having a shaft removably attaching, at a first end portion thereof, to the counterbore. The shaft and the counterbore are disposed in parallel with the longitudinal axis.

An assembly for use with a gas turbine engine, said assembly comprising: a bearing assembly;a tie rod for extending radially outwardly from said bearing assembly along a central longitudinal axis, said tie rod having: a body including a hollow length extending along said longitudinal axis said longitudinal axis extends through a cooling passage in said tie rod,a base having a width normal to said longitudinal axis, said base having a counterbore disposed therein, wherein said base is wider than a width of said body and the counterbore is not coaxial with said longitudinal axis, anda first connector attaching said base of said tie rod to said bearing assembly, said connector having: a hollow body having a shaft removably attaching, at a first end portion thereof, to said counterbore,wherein said shaft and said counterbore are disposed in parallel with said longitudinal axis. 11. The assembly of claim 10 wherein a ratio of said base of said tie rod to a length of said tie rod is greater than 0.25:1. 12. The assembly of claim 10 wherein said width parallel to a latitudinal axis of said base is bisected by said longitudinal axis. 13. The assembly of claim 10 wherein said width of said base is offset from said longitudinal axis and has a thicker portion to offset a bending moment on said tie rod. 14. The assembly of claim 10, wherein said longitudinal axis extends through a cooling passage in said tie rod and said counter bore is offset with said longitudinal axis of said cooling passage in an axial direction of said gas turbine engine. 15. The assembly of claim 10, wherein said base includes an eccentric portion at least partially defined by said counterbore. 16. The assembly of claim 10, wherein said first connector includes a bolt having a head for engaging said bearing assembly and said bolt includes a threaded portion spaced from said head by a narrowed neck. 17. The assembly of claim 10, wherein said first connector includes a bolt having a head located on a first side of said bearing assembly and said tie rod is located on a second side of the bearing assembly from said head of said bolt.
