Abstract
The support structure for the bearing compartment for a gas turbine engine includes eight radial tie bolts connected with the clevis wherein the outer diameter clevis is connected to the mount ring with an accessible bolt for easy assembly and disassembly. The tie bolts, while preloaded in tension, can accept compressive loads during severe loading operation conditions. The turbine exhaust case housing the tie bolts and bearing compartment are designed to facilitate cooling and maintainability at reduced costs.
