(4A-FE, 5A-FE, 2C)
A) Unscrew the nipple bolt and remove the gasket.
- Tightening torque - 52 Nm
(3S-FE, 4S-FE)
A) Using the special tool, disconnect the discharge line from the pump housing.
- Tightening torque - 45 Nm
b) Using adapters, connect the pressure gauge as shown in the figure.
Attention: during installation, the pressure gauge valve must be open.
2. Bleed the power steering system.
3. Warm up the working fluid.
A) Start the engine and set the idle speed.
b) Turn the steering wheel from lock to lock two or three times to warm up the fluid.
- Fluid temperature - 75-80°C
4. Check the pressure of the working fluid with the pressure gauge valve closed. Close the pressure gauge valve and measure the pressure.
Minimum allowable pressure:
- 4A-FE, 5A-FE, 7A-FE - 6500-7000 kPa
- 3S-FE, 4S-FE - 7000-7500 kPa
- 2C - 7500-8000 kPa
Attention:
- - Do not keep the tap closed for more than 10 seconds.
- - Do not let the operating fluid temperature become too high.
5. Check fluid pressure with gauge valve open.
A) With the engine idling, open the tap fully.
b) Measure fluid pressure at engine speeds of 1000 rpm and 3000 rpm.
- The maximum allowable pressure difference is 500 kPa
Note: Do not turn the steering wheel.
6. Check the fluid pressure when the steering wheel is turned to the extreme position.
With the engine idling and the valve fully open, turn the steering wheel to the maximum angle.
Minimum allowable pressure:
- 4A-FE, 5A-FE, 7A-FE - 6500-7000 kPa
- 3S-FE, 4S-FE - 7000-7500 kPa
- 2C - 7500-8000 kPa
Attention:
- - Do not hold the steering wheel in the end position for more than 10 seconds.
- - Do not let the operating fluid temperature become too high.
7. Disconnect the pressure gauge and connect the discharge line to the pump body.
8. Bleed the power steering system.
