INSPECTION

BASIC INSPECTION

Perform the following inspection procedures and repair or replace defective parts.

No.

Parts

Inspection

Corrective action

1

Oil pump (Exterior)



Replace the oil pump with a new one.



Measure the radial play and axial play.

If any of these exceeds the service limit, replace the oil pump with a new one.

2

Pulley



Replace it with a new one.



Measure the V ditch deflection.

If it exceeds the service limit, replace the pulley with a new one.

3

Oil pump (Interior)



Check the resistance to rotation of pulley.

If it is past the service limit, replace the oil pump with a new one.



Oil pump emits a noise that is markedly different in tone and loudness from a sound of a new oil pump when turning with a string put around its pulley, replace the oil pump with a new one.

4

O-ring

Crack or deterioration

Replace it with a new one.

5

Bracket

Crack

Replace it with a new one.



SERVICE LIMIT

Make a measurement as follows. If it exceeds the specified service limit, replace the parts with new ones.

Important
• Fix the oil pump on a vise to make a measurement. At this time, hold the oil pump with least possible force between two wood pieces.

• Do not set outside of flow control valve or pulley on a vise; otherwise outside or pulley might be deformed. Select properly sized wood pieces.


Play of the pulley shaft

Condition:

P: When applying the force of 9.8 N (1.0 kgf, 2.2 lb)

Service limit:

Radial play (Direction )

0.4 mm (0.016 in) or less


(1)

Dial indicator



Axial play (Direction )

0.9 mm (0.035 in) or less


(1)

Dial indicator



Ditch deflection of pulley

Service limit:

1.0 mm (0.039 in) or less

Note

Read the value for one surface of V ditch, and then the value for another off the dial.

Dial indicator



Resistance to rotation of pulley

Service limit:

Maximum load; 9.22 N (0.94 kgf, 2.07 lb) or less


Note
• A rather higher value may be indicated when pulley starts turning.

• Measure the load during rotation and make a judgment.

Spring balance




HYDRAULIC PRESSURE

Note
• Be sure to complete all items aforementioned in “INSPECTION”, prior to measuring hydraulic pressure. Otherwise, pressure can not be measured correctly.

• Do not leave the valve of pressure gauge closed or hold the steering wheel at stop end for 5 seconds or more in any case, as the oil pump may be damaged due to long keep of these conditions.

• Put a cotton cloth waste at a place where fluid drops before the pressure gauge is installed. Wipe off split fluid thoroughly after the measurement.


REGULAR PRESSURE MEASUREMENT

Connect the ST1, ST2 and ST3.

ST1 32005189 PRESSURE GAUGE

ST2 32005042 ADAPTER HOSE B

ST3 32005041 ADAPTER HOSE A

Remove the air intake duct.

Disconnect the pipe C from the pump.

Using the gasket (Part No. 32006872) and bolt (Part No. 32006871), install the ST2 to the pump instead of pipe C.


(1)

Bolt A

(2)

Pipe C

(3)

Pipe D



Install the ST3 to end of pipe C removed from pump.

Replenish power steering fluid up to the specified level.

Open the valve, and start the engine.

Measure the regular pressure.

ST1 32005189 PRESSURE GAUGE

ST2 32005042 ADAPTER HOSE B

ST3 32005041 ADAPTER HOSE A


Service limit:

981 kPa (10 kg/cm 2 , 142 psi) or less

If it is not within the specified value, replace the troubled part caused by the following symptoms; pipe or hose clogged, leaks from fluid line, and mix of foreign objects in fluid line.

Measure the relief pressure.

Using the STs, measure the relief pressure.

Close the valve.

Measure the relief pressure.

ST1 32005189 PRESSURE GAUGE

ST2 32005042 ADAPTER HOSE B

ST3 32005041 ADAPTER HOSE A


Service limit:

Saab 9-2X 2.5i Linear:

6,767 — 7,453 kPa (69 — 76 kg/cm 2 , 981 — 1,081 psi)

Saab 9-2X 2.0T Aero:

7,350 — 8,036 kPa (75 — 82 kg/cm 2 , 1,067 — 1,165 psi)

If it is not within the specified value, replace the oil pump.

Measure the working pressure.

Using the STs, measure the working pressure.

Open the valve.

Measure the working pressure of control valve by turning wheel from stop to stop.

ST1 32005189 PRESSURE GAUGE

ST2 32005042 ADAPTER HOSE B

ST3 32005041 ADAPTER HOSE A


Service limit:

Saab 9-2X 2.5i Linear:

6,767 — 7,453 kPa (69 — 76 kg/cm 2 , 981 — 1,081 psi)

Saab 9-2X 2.0T Aero:

7,350 — 8,036 kPa (75 — 82 kg/cm 2 , 1,067 — 1,165 psi)

If it is within the specified value, measure the steering effort. If it is not within specified value, replace the control valve itself or control valve and pinion as a single unit with new ones.
