Steering (11.00)
Power Steering (11.02)
Description
The power steering system comprises of a non-speed
sensitive rack and pinion steering gear together with an
engine driven vane pump, operating at a constant flow rate.
The level of assistance is co ntrolled via a rotary hydraulic
valve, integral to the steering gear assembly.
Hoses / pipe are used to transm it hydraulic fluid throughout
the steering system. The high -pressure line contains a
pressure transducer, which sends an electronic signal to the
engine management system. This ensures engine RPM is
maintained when the steering system draws higher loads
from the engine (i.e. during parking manoeuvres.) In order
to regulate system temperatures, a wire-wound cooler is
incorporated into the return line.Specifications
