Overall walk-around of the turbopumps.

Picture 3 of 6.

The LOX turbopump is in the foreground.

The two circular red closures under the LOX turbopump cover the accessory drive adapter; these consist of two counter-rotating gears, powered by the turbopump gearbox. The main hydraulic pump (used power the gimbal actuators) connects to one of the adapters (I was unable to determine what attached to the upper, center adapter; this component is present only on early H-1 engines and is absent from later models).

Note the fuel additive blender unit (silver cylinder to the left of the accessory drive adapter).
