STEERING SYSTEM
2) Measurement of hydraulic pressure
Note: Be sure to complete all items aforementioned in article 1), prior to measuring hydraulic pressure. Otherwise, pressure can
not be measured correcdy.
Measure regular pressure
~
Flattened pipes or hoses Replace bad parts
I 1
at idling with valve opened.
J
(Refer to Fig. 11·158)
~
Leakage of fluid line Retighten or replace
Result: 981 kPa(lOkg/cm2,
142 psi) or less
Obstacle in fluid line
Replace fluid or com·
ponent of fluid line
GOOD
Measure relief pressure at
?r
Poor work of relief valve
>
Replace oil pump
assembly
idling with valve closed.
(Refer to Fig. 11·159)
Fluid leakage inside oil
Result: 4,609 to 5,884 kPa
~
pump Assy
(47 to 60 kg/ cm 2 ,
668 to 853 psi)
Excessive wear of vane
GOOD
pump mechanism
Measure working pressure at
idling with valve opened,
turning steering wheel from
stop to stop.
Poor work of control valve
Replace gear box assembly
(Refer to Fig. 11·160)
-
Result: 4,609 to 5,884 kPa
(47 to 60 kg/cm 2 ,
668 to 853 psi)
NOTE:
I.
Do not lelve the valve of pressure gauge closed or hold the steering wheel at stop end for 5 seconds or more in any case,
IS
the oil pump may be damaged due to long keep of these conditions.
b. Put cotton cloth
waste
at a place where fluid drops before pressure gauge is installed. Wipe off spilt fluid thoroughly after the
melsurement
c. Keep engine idling during the measurement.
