Detail of the accessory drive adapter, on the gearbox below the LOX turbopump.

The accessory drive adapter consists of two counter-rotating gears, powered by the turbopump gearbox. The main hydraulic pump (used power the gimbal actuators) connects to the left-hand adapter (I was unable to determine what attached to the other adapter).
