Pic. 12.10. Adjustment screw location (1) pressure in the control system
2. The pressure in the underdrive clutch line is adjusted using the adjusting screw shown in fig. 12.10. Turning the adjusting screw to the left increases the pressure. One turn of the adjusting screw changes the pressure by 35 kPa.
Adjust the pressure in the underdrive clutch line so that it corresponds to the average value of the nominal range.
The nominal pressure range is 1010–1050 kPa.
3. Reinstall the control valve block cover and fill the gearbox with fluid.
4. Check the pressure.
5. Re-adjust system pressure if necessary.
