Power Steering - Power-Assisted Recirculating Ball: Description

Power steering system is composed of power steering pump, steering gear and connecting hoses. All pumps have integral reservoirs. Both ZF and VT49 type pumps are used; some of these pumps are made of a light alloy material. The light alloy pumps are interchangeable with the cast iron type.

All power steering pumps are engine driven vane type with a control valve. The purpose of the power steering gear pump is to supply fluid (under pressure) to the steering gear.

Steering gear has integral piston/steering nut. Fluid pressure to each side of piston/steering nut is controlled by a control valve which is moved by a lever from steering column shaft.
