5) Check relief pressure
a) Increase engine speed to about 1,500 r / min (rpm). Close
gauge valve gradually while watching pressure increase indi-
cated by gauge and take reading of relief pressure (maxi-
mum hydraulic pressure).
Relief pressure:
7650 – 8350 kPa (76.5 – 83.5 kg / cm
2
, 1088 – 1187 psi)
D
When it is higher than specified values, possible cause is
malfunction of relief valve.
D
When it is lower than specified values, possible cause is ei-
ther failure of P / S pump or settling of relief valve spring.
CAUTION:
Be sure not to close gauge valve for longer than 10 se-
conds.
b) Next, open gauge valve fully and increase engine speed to
about 1,500 r / min (rpm). Then turn steering wheel to the left
or right fully and take reading of relief pressure.
Relief pressure:
7650 – 8350 kPa (76.5 – 83.5 kg / cm
2
, 1088 – 1187 psi)
D
When it is higher than specified values, possible cause is
malfunction of relief valve.
D
When it is lower than specified values, possible cause is fail-
ure in steering gear box. Replace gear box.
CAUTION:
Be sure not to hold steering wheel at fully turned posi-
tion for longer than 10 seconds.
