Installing Test Equipment
To install the pressure test equipment:
- Place a suitable drain tray below the power steering pump.
- Install a hose clamp on the reservoir to pump hose prior to disconnecting any hoses, to avoid unnecessary loss of fluid.
- Disconnect the hose from the power steering pump high pressure outlet.
- Install the pump outlet to hose adaptor (5). Do not omit the 'O' ring seal (9).
- Connect the power steering pump adaptor to control valve hose (6) of the test equipment.
- Install the adaptor (4) in the high pressure hose previously removed from the power steering pump outlet.
- Connect the connector (3) of the test equipment hose (2) to the adaptor (4).
- Remove the hose clamp from the reservoir hose.
- Start the engine to check the system pressure.
With the control valve (7) OPEN and the engine idling, the following system pressures may be checked:
- During turning when static (dry parking pressure).
- When the steering is held on full lock (maximum system pressure or pressure relief).
- With the steering at rest (idle pressure or back pressure).
CAUTION:
To avoid excessive heating of the power steering pump when CHECKING the pressure, do not close the valve for more than 5 seconds maximum.
CAUTION:
When CHECKING the pump pressure DO NOT drive the vehicle with the test equipment installed.
With the control valve (7) CLOSED the power steering pump maximum output pressure can be checked.
