The 708 Series
Saginaw power steering gear has a recirculating ball system. The ball system
acts as a rolling thread between the worm shaft and the rack piston. The
following items support the worm shaft:
The rack piston moves up in the gear when the worm shaft turns right.
The rack piston moves down in the gear when the worm shaft turns left. The
rack piston teeth mesh with the sector. The sector is a part of the pitman
shaft. Turning the worm shaft turns the pitman shaft. The pitman shaft
turns the wheels through the steering linkage.
The control valve in the steering gear directs the power steering fluid
to either side of the rack piston. The rack piston converts the hydraulic
pressure into a mechanical force. If the steering system becomes damages
and loses the hydraulic pressure, the vehicle can be controlled manually.
