Reducing Pressure

ADJUSTMENT OF REDUCING PRESSURE

1. Remove parts up to the oil filter in the same way as for adjustment of the line pressure. The valve body need not be removed.





2. Turn the adjustment screw of the lower valve body and adjust it so that the reducing pressure is within specifications. When the adjustment screw is turned to the right the reducing pressure becomes lower; when it is turned to the left, it becomes higher.

Standard value: 425 ± 10 kPa (60 ± 1 psi, 4.3 ± 1 kg/cm2)

Oil pressure change:
For each turn of adjustment screw 30 kPa (6 psi, 0.45 kg/cm2)

3. Install the oil filter and oil pan in the same way as for adjustment of the line pressure.
4. Make the oil pressure test. Readjust if necessary.
