B. Steering Wheel and Column
C. HFB 70 Steering Gear
D. Steering Linkage consisting of a Pitman arm. drag link,
steering arm and tie rod.

ment. These items are covered in their respective sections of

SYSTEM OPERATION
Power steering is accomplished by hydraulic pressure.
Steering fluid is supplied by a vane-type hydraulic pump,
mounted at the left rear of the engine. Hydraulic fluid lines
(figure 11-2) are mounted fre>m the power steering reservoir to ·
the pump. Fluid displaced by the pump circulates through flexi-
ble lines to the power steering gear. A return line is connected
from the steering gear back to the reservoir.
