Hydraulic lines: Removing

WARNING: This page is about a different car, the 2011 Saab 9-3 and 2010 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

The following is a description of changing the hydraulic lines on the hydraulic unit only. Changing hydraulic lines to the hydraulic cylinder is illustrated in the instructions for the respective hydraulic cylinder. See SOFT TOP COVER HYDRAULIC CYLINDER , HYDRAULIC CYLINDERS FOR LOCKING FIRST BOW , SOFT TOP HYDRAULIC CYLINDER  or SIXTH BOW HYDRAULIC CYLINDER .

It is not always necessary to dismantle the entire hydraulic cylinder when changing its hydraulic lines.

  1. Close the soft top completely.
  2. Remove Luggage compartment side trim, CV. See LUGGAGE COMPARTMENT TRIM, CV .
  3. Undo the nuts to the hydraulic unit and lift it out somewhat to access the connections.
    IMPORTANT: Lift up the hydraulic unit carefully so that the hydraulic hoses are not damaged.

    IMPORTANT: If several hydraulic lines are being replaced, they must be marked together with their connections to the hydraulic unit and hydraulic cylinders. They must not be mixed up. The hydraulic lines are marked with the same number at both ends and are different lengths. In addition, the entries through the attaching plate are marked to avoid confusion.
  8. Pull out the hydraulic line from the attaching plate.
  9. Remove the cable tie and open the hydraulic line attachments.
  10. Detach the relevant hydraulic line from the side of the hydraulic cylinder. See SOFT TOP HYDRAULIC CYLINDER , HYDRAULIC CYLINDERS FOR LOCKING FIRST BOW , SIXTH BOW HYDRAULIC CYLINDER  or SOFT TOP COVER HYDRAULIC CYLINDER .
  11. Take out the hydraulic line.
