3. With engine idling, turn steering wheel and warm up engine till temperature of fluid in tank rises to 50 - 60° C (122 - 140° F).
4. Check back pressure by measuring hydraulic pressure with engine idling and hands off steering wheel.
Back pressure: Lower than 980 kPa (10 kg/cm2, 142 psi)
When back pressure is higher than 980 kPa (10 kg/cm2, 142 psi), check control valve and piping for clogging.
5. Relief pressure check
^
Increase engine speed to about 1,500 r/min (rpm). Close gauge valve gradually while watching pressure increase indicated by gauge and take
reading of relief pressure (maximum hydraulic pressure).
Relief pressure: 5700 - 6400 kPa (58 - 65 kg/cm2, 825 - 924 psi)
^
When it is higher than 6400 kPa (65 kg/cm2, 924 psi), possible cause is malfunction of relief valve.
^
When it is lower than 5700 kPa (58 kg/cm2, 825 psi), possible cause is either failure of P/S pump or settling of relief valve spring.
CAUTION: Be sure not to close gauge valve for longer than 10 seconds.
