POWER STEERING HYDRAULIC SYSTEM - Continued
The fluid reservoir (3) is shared with the main hydraulic system.
The steering wheel (4) rotates a gear that positions a spool in the main steering gear. This
motion is hydraulically sent to a piston in the slave gear (5) causing it to follow the rotation
of the main steering gear.
The main gear pitman arm (6) is mechanically connected to the slave gear pitman arm (7).
These pitman arms move the steering mechanism on the front axles (8) left or right causing
the vehicle to steer left or right.
On M984A4 wrecker, the power is supplied to the main steering gear by an engine drive
steering/tensioner pump.
