The fluid reservoir (2) is shared with the main hydraulic system.
The steering wheel (3), which is mechanically linked to the main steering gear, rotates a
gear that positions a spool in the main steering gear.
This motion is hydraulically transmitted to a piston in the slave gear causing it to follow the
rotation of the main gear.
The main gear pitman arm (4) is mechanically connected to the slave gear pitman arm.
