Steering system
N-2
3. Exhaust the air from the system.
4. Fully open the pressure gauge valve.
5. Start the engine and back and forth several
times the steering wheel to the maximum
wheel, increasing the temperature of steering
liquid up to 50°-60°C{122-140°F}.
Caution:
● If the valve is closed more than 5s, the
temperature of power steering fluid will raise
very high and result in adverse effect on the
power steering pump.
6. Completely close the pressure gauge valve.
7. Increase the engine speed up to 1000-1500rpm
and measure the pressure of power steering
liquid.
● If the hydraulic pressure is not within the
specified range, repair or replace the
components of power steering pump.
Hydraulic pressure of power steering oil pump:
9.85-10.35Mpa
Caution
● If the steering wheel holds its maximum
steering position for more than 5s, the
temperature of power steering liquid will
increase very slow and have adverse effect on
the oil pump of power steering oil pump.
8. Fully open the pressure gauge valve and
increase the engine speed up to 1, 000-
1,500rpm;
9. Turn back and forth several times the steering
wheel to the maximum the steering wheel and
measure the hydraulic pressure produced in the
steering casing.
● If the pressure is not within the specified range,
repair or replace the steering components.
Pressure of steering liquid: 9.85-10.35Mpa
10. Remove the special tool
11. Install and screw in the HP tube and have the
tightening torque stay within the defined scope.
Tightening torque: 30-44N.m {3.0-4.5kgf.m ,
22-32ft1·lbf}
12. Exhaust the air from the system.
Check of steering wheel and steering
column
Check of steering wheel “run-out”
1. Stop the wheels in a position facing the front,
and slightly turn around the steering wheel to
confirm whether the amplitude of run-out is in
the specified range.
● if the amplitude of run-out is not within the
specified range, it is possible that the steering
knuckle is worn or the clearance of steering
gear excessive, the correction has to be made
as necessary.
Oscillation amplitude: 0-30mm {0-1.18in}
Check of steering wheel looseness
1. Swing the steering wheel in the direction as
shown in Fig..Check the swings of bearing
sleeve of steering column and steering shaft
hinge, the looseness of steering wheel and
steering column etc.,
