1-27.1. STEERING CONTROL SYSTEM OPERATION (SERIAL NUMBERS 300000 AND ABOVE)
Major components of the steering system are:
A
OIL RESERVOIR
– The oil reservoir serves as an oil filling point.
B
HYDRO-BOOSTER
– Converts hydraulic power from the steering pump to mechanical power to
the master cylinder, providing power assist during braking.
C
STEERING GEAR
– Converts hydraulic power from steering pump to mechanical power at
pitman arm.
D
POWER STEERING COOLER
– Directs power steering fluid through a series of fins or baffles so
outside air can dissipate excess heat before the fluid is recirculated through the steering system.
E
SERPENTINE BELT
– Transmits mechanical driving power from crankshaft drive pulley to
steering pump pulley which drives the steering pump.
F
STEERING PUMP
– Supplies the oil under pressure throughout the steering system.
