STEERING
INSPECTION
Visual check
Check the following parts:
•
Oil leakage.
•
Steering system for looseness or damage.
•
Steering function
•
Joint ball for oil leakage or damage.
•
Joint ball rubber boot for damage.
MAINTENANCE
The hydraulic system should be kept clean and fluid level
in the reservoir should be checked at regular intervals and
fluid added when required. Refer to "MAINTENANCE AND
LUBRICATION" in section 0B of the manual for type of
fluid to be used and intervals for filling.
If the system contains some dirt, flush it as detailed later
in this section. If it is exceptionally dirty, both the pump
and the gear must be completely disassembled before
further usage.
All tubes, hoses, and fittings should be inspected for
leakage at regular intervals. Fittings must be tight. Make
sure the clips, clamps and supporting tubes and hoses are
in place and properly secured.
Power steering hoses and lines must not be twisted,
kinked or tightly bent. Air in the system will cause spongy
action and noisy operation. When a hose is disconnected
or when fluid is lost, for any reason, the system must be
bled after refilling. Refer to "Bleeding the Power Steering
System" in this section.
FLUID LEVEL
1.
Run the engine until the power steering fluid reaches
normal operating temperature, about 55°C (130°F),
then shut the engine off.
2.
Check the level of fluid in the reservoir.
3.
If the fluid level is low, add power steering fluid as
specified in "MAINTENANCE AND LUBRICATION" in
section 0B to the proper level and install the receiver
cap.
4.
When checking the fluid level after the steering
system has been serviced, air must be bled from the
system. Refer to "Bleeding the Power Steering
System" in this section.
