NOTES Make sure that the repair work is performed carefully. Otherwise renewed leaks may occur.

IMPORTANT In the event of damage to compressed-air terminals (1a) and pressure lines (4) a compressed-air connector (3) or a repair screwed connection (1) can be mounted.

  1. Unscrew compressed-air line connection (1a) from affected component part (e.g. suspension strut).
  2. Cut off pressure line (4) using an isolating bladeSPECIAL TOOL at a suitable point.

    NOTES Special care must be taken to ensure that the cut is exactly at right angles to the pressure line (4).

    Otherwise the pressure line (4) may suffer more leaks.

  3. Insert pressure line (4) into pressure line connector (3) up to end stop or to at least 19.5 mm.
  4. Pull back pressure line (4) slightly, to enable the surrounding retaining edges inside the clamping ring (1b) to engage in the outer surface of the pressure line (4).
  5. Cut repair line (2) so that the original length and form (straight end or 90° curved section) of the pressure line (4) to be repaired is reached again.

    NOTES When cutting off the repair line (2) take into account the insertion depths in the repair screwed connection (1) and pressure line connector (3). Leaks can occur otherwise.

    NOTES Special care must be taken to ensure that the cut is exactly at right angles to the repair line (2). Otherwise renewed leaks may occur.

  6. Insert repair line (2) into pressure line connector (3) up to end stop or to at least 19.5 mm.

    NOTES Do not kink pressure line (4) and repair line (2).

    Otherwise the pressure line (4) or the repair line may be damaged (2).

    IMPORTANT A repair line (2) with a straight and a curved section is available as replacement part.

  7. Pull back repair line (2) slightly, to enable the surrounding retaining edges inside the clamping ring (1b) to engage in the outer surface of the repair line (2).
  8. Screw repair connection (1) into the affected component. Model 257

    IMPORTANT Depending on the size of the repair threaded connection (1), use the SPECIAL TOOL box wrench bit (140 589 00 03 00) or the SPECIAL TOOL box wrench bit (001 589 00 03 00).

  9. Pull plastic guard (1c) out of repair connection (1).
  10. Insert repair line (2) into repair threaded connection (1) up to end stop or to at least to 19.5 mm.
  11. Pull back repair line (2) slightly, to enable the surrounding retaining edges inside the clamping ring (1b) to engage in the outer surface of the repair line (2).
  12. Route pressure line (4) on vehicle.

    NOTES When pulling in or routing the pressure line (4) on the vehicle make sure that the pressure line (4) cannot be twisted once fastened. A twisted pressure line (4) can be damaged and consequently be leaky.
