C Failing to purge the system of air.

D Having both hydraulic pumps running at the same time.

Питання 5

Which of the following statements best describes the importance of the purity of the hydraulic oil used in steering gear?

A Even small solid particles will cause wear, whilst moisture will cause corrosion.

B Provided the oil remains incompressible, the steering gear will continue to work correctly.

C Provided the oil viscosity remains within acceptable limits, the steering gear will continue to work correctly.

D Steering gear power actuators are very robust and therefore a degree of oil contamination can be tolerated.
