Abstract
A gas turbine includes a shaft, a turbine coupled with the shaft for rotation with the shaft, and a bearing coupled with the shaft to facilitate rotation of the shaft. A bearing nut is adjacent the bearing on the shaft. The turbine has a first load path and the bearing has a second load path. The bearing nut exerts a force on the bearing such that the first load path is not aligned with the second load path relative to a central axis of the gas turbine engine. A method of assembling a gas turbine engine is also disclosed.
