Abstract
A fan drive gear system for a turbine engine includes a carrier that supports rotation of a plurality of planet gears and is rotatable about an engine longitudinal axis. The carrier includes an axially facing seal plate that defines a lubricant passage to the carrier. A transfer bearing assembly has a seal member that defines a lubricant supply path to the seal plate and at least one biasing member that biases the seal member against the seal plate.
