Hydraulic unit pressure switch (ABS) - removal and refitting

Note: To remove the pressure switch from the hydraulic unit in situ, Ford tool No 12-008 or a locally made equivalent will be required. The switch may be removed without special tools after removing the hydraulic unit complete or the pump above. A new O-ring must be used when refitting the switch.

See why preventative maintenance is recommended after our washing machine repair services.

Caution: Refer to the
precautions in Section 1.
