Overall view of the forward end of the engine.

Picture 1 of 2.

At the top of the engine (as it rests on its dolly) is the LOX turbopump. Directly under the LOX TP are the two accessory drive adapters; the one at left has the main hydraulic pump mounted on it and the one at right has a circular, white closure.

Below and to the left of the main hydraulic pump is the fuel additive blender unit (FABU) in its red heater assembly. Directly below that is the dark grey auxiliary hydraulic pump, with the larger, silver hydraulic system accumulator/reservoir below that.

At the extreme right of the engine is the gimbal bearing.
