LUBRICANTS DESCRIPTION

CHECKING STEERING WHEEL RETURN

Check the steering wheel return and confirm the following points

Scheme 22

1. The force required to turn the steering wheel and the wheel return should be the same for both left and right in case of moderate or sharp turns.
2. When the steering wheel is turned 90° and held for a couple of seconds while the vehicle is being driven at 35 kph, the steering wheel should return 70° or more. NOTE: If the steering wheel is turned very quickly, steering may be momentarily difficult. This is not a malfunction because the oil pump output will be somewhat-decreased.

Scheme 23

Scheme 24

Scheme 25

1. Press the V belt, applying a pressure of 98 N (10kg, 22lb) at the specified point and measure the deflection to confirm that it is within the standard value. Standard value New belt: 8.8 ~ 11.0 mm (0.04 ~ 0.43 in.) Used belt: 12.5 ~ 14.3 mm (0.49 ~ 0.56 in.)
2. If the belt deflection is beyond the standard value, adjust the belt tension as follows. Loosen the bolt adjusting (A) the power steering "V" belt tension. Put a bar (A) or equivalent, between the bracket (B) and the oil pump (C) and adjust the tension so that the belt deflection is within the standard value. Tighten the bolt adjusting the power steering "V" belt tension. Check the belt deflection and adjust it again if necessary. CAUTION: After turning the V belt in the normal rotation direction more than once, recheck the belt deflection.

Scheme 26

1. Position the vehicle on a level surface.
2. Start the engine. With the vehicle kept stationary, turn the steering wheel several times continuously to raise the fluid temperature to 50 - 60°C (122 to 140°F).
3. With the engine at idle, turn the steering wheel fully clockwise and counterclockwise several times.
4. Make sure there is no foaming or cloudiness in the reservoir fluid.
5. Stop the engine to check for any difference in fluid level between a stationary and a running engine. NOTE: If the fluid level varies 5 mm (0.2 in.) or more, bleed the system again. If the fluid level suddenly rises after stopping the engine, further bleeding is required. Incomplete bleeding will produce a chattering sound in the pump and noise in the flow control valve, and lead to decreased durability of the pump.

AIR BLEEDING

1. Fill the power steering fluid reservoir up to the "MAX" position with specified fluid.
2. Jack up the front wheels.
3. Disconnect the ignition coil high tension cable, and then, while operating the starter motor intermittently (for 15 to 20 seconds), turn the steering wheel all the way to the left and then to the right five or six times. NOTE: When bleeding fluid, replenish with the fluid so that the level does not fall below the bottom of the filter. If air bleeding is done while the vehicle is idling, the air will be broken up and absorbed into the fluid. Be sure to do the bleeding only while cranking.
4. Connect the high tension cable, and then start the engine (idling).
5. Turn the steering wheel to the left and then to the right, until there are no air bubbles in the oil reservoir. NOTE: Do not hold the steering wheel turned all the way to either side for more than ten seconds.
6. Confirm that the fluid is not milky and that the level is between "MAX" and "MIN" mark on the reservoir.
7. Check that there is a little change in the fluid level when the steering wheel is turned left and right. NOTE: If the fluid level varies 5mm (0.2 in.) or more, bleed the system again. If the fluid level suddenly rises after stopping the engine, further bleeding is required. Incomplete bleeding will produce a chattering sound in the pump and noise in the flow control valve, and lead to decreased durability of the pump.

Scheme 27

1. Disconnect the pressure hose (B) from the pump (A). Connect the special tool between the pump and the pressure hose as illustrated.
2. Bleed the air, and then start the engine and turn the steering wheel several times, measure the fluid temperature by Temperature gauge so that the fluid temperature can rise to approximately 50°C (122°F).
3. Increase the engine speed to 1,000 RPM.
4. Close the shut-off valve of the special tool and measure the fluid pressure to confirm that it is within the standard value range. Standard value Oil pump pressure Relief pressure: 8.6~9.1 MPa (88~93 kg.cm 2 , 1251~1322 psi) CAUTION: Do not keep the shut-off valve on the pressure gauge closed for more than ten seconds.
5. Remove the special tools, and tighten the pressure hose (B) against the oil pump (A) using the specified torque. Tightening torque 65~75 Nm (650~750 kgf.cm, 47.9~54.2 lbf.ft)
6. Air bleed the system. (see «AIR BLEEDING»(ref-276681-S15870432632008011000000) )
