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.
With the control valve (7) OPEN and the engine idling, the following system pressures may be checked:
- During turning.
- When the steering is held on full lock.
- With the steering at rest.
CAUTION:
To avoid excessive heating of the power steering pump, do not close the valve for longer than 5 seconds maximum.
CAUTION:
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.
