Residual Pressure Retaining Valve

Residual Pressure Retaining Valve

Special tools, testers and auxiliary items required

• Socket (T10158/1)

• Insert Tool (T10212)

• Residual pressure retaining valve must only be replaced if it was damaged during removal and installation or servicing of suspension strut (air suspension) or if air is not released from it anymore (it sticks).

• With suspension strut (air suspension) removed, no further preparation is needed to replace residual pressure retaining valve.

• If residual pressure retaining valve sticks, the vehicle must be on a hoist and the wheels must rotate freely in order to replace the valve..

• When removing air line, there is the possibility that the residual pressure retaining valve will also be removed.

• If vehicle is not raised with a hoist, vehicle sinks immediately on side where residual pressure retaining valve was removed. There is a strong risk of injury because the arms are clamped.

• Vehicle must remain on hoist until a new residual pressure retaining valve is installed and suspension strut (air suspension) is refilled.

Removing

• This procedure applies to replacement of residual pressure retaining valve with suspension strut (air suspension) installed.

- Position the vehicle on the lifting platform and raise it until the wheels rotate freely.

- Clean area around wiring connection.

- Remove air supply line and seal off connectors.






- Remove residual pressure retaining valve - 1 - with (T10158/1) - 2 - from suspension strut (air suspension).






Installing

Install in reverse order of removal.

- Tighten the residual pressure valve to 10 Nm using a (T10158/1).

- Fill suspension strut (air suspension) using vehicle diagnostic tester. Refer to => [ System, Venting or Filling ] System, Venting or Filling.
