REDUCING PRESSURE ADJUSTMENT (WITHOUT SCAN TOOL)
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 so that the reducing pressure is the standard value. When the adjustment screw is turned to the right, the reducing pressure becomes lower; when it is turned to the left,it becomes higher.

NOTE: When adjusting the reducing pressure, aim for the center value (425 kPa, 60 psi) of the standard value allowance.

Standard value:
425±10 kPa (60±1 psi, 4.3±1 kg/cm2)
Oil pressure change for each turn of adjustment screw:
30 kPa (4.3 psi, 0.3 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.

CAUTION: This adjustment should be made at an oil temperature of 70-80°C (158-176°F). If the adjustment is made at a temperature that is too high, the line pressure will drop during idling, with the result that is might not be possible to make the correct adjustment.
