Steering wheel play
1. Check steering wheel play.
A) Set the wheels to the straight ahead position.
b) Measure the steering wheel play on the rim, the wheels do not turn when the steering wheel is turned lightly in both directions.
Maximum backlash - 40 mm
V) If the play exceeds the maximum value, then adjust or repair the steering gear.
2. Set wheels to straight ahead.
3. Steering adjustment
A) Loosen the locknut.
b) Turn the adjusting screw clockwise to decrease the play.
Note: turn the adjusting screw a little and check the play after each turn of the screw.
4. Check for steering gear sticking.
A) Turn the steering wheel half way in both directions.
b) Check the amount of play, the smoothness of the steering wheel and the absence of jamming.
5. While holding the adjusting screw, tighten the locknut.
Fluid level
1. Place the car on a level surface.
2. With the engine stopped, check the fluid level in the reservoir. Add if necessary.
Attention: if the working fluid is heated, then measure the level on the scale "NOT", if cold - on a scale "COLD".
3. Run the engine to idle.
4. Turn the steering wheel from lock to lock several times to warm up the working fluid to a temperature of 80°C.
5. Check up absence of foam and turbidity of a liquid in a tank. If necessary, bleed the system.
6. With the engine running, measure the fluid level.
7. Stop the engine and check the difference in fluid levels in the reservoir with the engine running and stopped. If the fluid level has changed noticeably, then the system should be bled.
Maximum level rise - 5 mm
Changing the working fluid
1. Hang the front wheels of the car.
2. Disconnect the return hose and drain the fluid into a suitable container.
Note: Turn the steering wheel from lock to lock to drain the working fluid.
3. Fill reservoir with fresh fluid. Working fluid: DEXRONII
4. Run the engine to idle. After 1-2 seconds, liquid will begin to flow from the return hose. At this point, stop the engine immediately.
Note: Keep some fluid left in the reservoir.
5. Repeat steps 3-4 several times to remove air from the liquid.
6. Connect the return hose and bleed the system.
Bleeding the system
1. Check the liquid level in the tank, add if necessary
2. Start the engine and turn the steering wheel from lock to lock several times.
3. With the engine running at a speed of no more than 1000 rpm, turn the steering wheel all the way to the right or left and hold it in this position for 2-3 seconds, then turn the steering wheel in the opposite direction, again holding it in this position 2-3 seconds.
4. Check up absence of foam and turbidity of a liquid in a tank.
5. Make sure that the fluid level does not rise above the maximum level when the engine is stopped.
6. Stop the engine and check the difference in fluid levels in the reservoir with the engine running and stopped.
Maximum level rise - 5 mm
7. If foaming or turbidity of the liquid is observed, the increase in the level of the working fluid exceeds 5 mm, then repeat the operations in steps 1-3.
Fluid pressure test
1. Connecting a pressure gauge.
A) Disconnect the pressure line fitting.
b) Connect the test gauge adapter inlet to the power steering pump and the outlet (after valve) - to the discharge line.
V) Pump the system. Start the engine and turn the steering wheel from lock to lock 2 or 3 times,
G) Check fluid level.
2. Check that the fluid temperature is at least 80°C.
3. Run the engine to idle.
4. Check the pressure of the working fluid with the pressure gauge valve closed and, if the pressure is low, repair or replace the pump.
Minimum pressure:
- models LJ - 75 kgf / cm2 (7.355 kPa)
- models KZJ — 85 - 90 kgf/cm2 (8.336 - 8.826 kPa)
Note:
- The pressure gauge valve must not remain closed for more than 10 seconds.
- Do not allow excessive temperature rise of the working fluid.
5. Check the pressure of the working fluid with the pressure gauge valve open, when the engine is running at 1000 rpm and 3000 rpm.
If the difference between readings at 1000 rpm and 3000 rpm is greater than the maximum, repair or replace the pump valve or power steering pump.
Maximum difference - 5 kgf / cm2 (490 kPa)
6. Checking the pressure when turning the steering wheel all the way.
A) With the engine idling, fully open the pressure gauge valve and turn the steering wheel fully left or right. Measure the pressure.
Minimum pressure:
models LJ - 75 kgf / cm2 (7.355 kPa)
models KZJ - 85-90 kgf / cm2 (8.336 - 8.826 kPa)
b) If the pressure is low, the steering gear is leaking and should be repaired or replaced.
Steering wheel force check
Note: Before checking, check the tire pressure, tire type and contact surface.
1. Stop the vehicle on a level surface and turn the steering wheel to the center position.
2. Run the engine to idle.
3. Using a dynamometer, measure the force on the steering wheel in both directions.
Maximum allowable force - 39 N
4. If the force on the steering wheel exceeds the maximum allowable value, repair the steering mechanism.
Checking the tension of the pump drive belt (LJ models)
1. Press the drive belt with a force of 98 N (10 kgf) at the point shown in the figure and measure the deflection of the belt.
Drive Belt Deflection:
new 8-12 mm
located
in operation 10 -15 mm
Note: A belt is considered new if it has been on the engine for less than 5 minutes.
2. Using a special tool, check the tension of the drive belt. Drive Belt Tension:
- new - 45 - 55 kgf
- in operation - 20 - 35 kgf
