Abstract
A disclosed intershaft seal assembly for a gas turbine engine includes a support fixed to a static structure. A first seal housing is supported radially outboard of the support for holding a first seal. A second seal housing is supported radially inboard of the support and supports a second seal. A first biasing member is provided between the support and the first seal housing that biases the first seal housing in a first direction away from the support. A second biasing member between the support and the second seal housing biases the second seal housing in a second direction away from the support.
