A bearing assembly includes a first gear shaft aligned with a first axis and a second gear shaft aligned with a second axis. The second axis is oriented parallel to the first axis. A first bearing is supported on the first gear shaft and a second bearing is supported on the second gear shaft. A coupling mechanism extends between and radially clamps the first bearing to the second bearing. The coupling mechanism is operable to restrict relative radial movement between the first bearing and the second bearing.

A two stage fuel delivery system for an aircraft includes a first stage pump including an inlet connected to a source of fuel and an outlet connected to a combustor assembly, and a second stage pump including an inlet portion connected to the source of fuel and an outlet portion connected to the combustor assembly. A bypass valve is connected between the source of fuel, the inlet, and the inlet portion. The bypass valve selectively disconnects the second stage pump from the source of fuel. A metering valve is connected to the inlet and the inlet portion. The metering valve includes a metering valve inlet and a metering valve outlet. A pressure regulating valve is connected to the metering valve. A stage monitoring system is configured to detect a change in operation of the second stage and control the bypass valve.
