Removing Outer Hinge Pillar

Information 

Possible separation points on the outer hinge pillar.

• The possible separation points on the outer hinge pillar can only be at the marked area -A-  and -B-  .
• If it is certain that there has been no deformation of the roof area structure, the upper separation point in area -C-  can be used for the following repair work.

1. 2.1. Position the side member separation point -A-  so that the outer hinge pillar spare part overlaps by approx. 40 mm. Mark the separation point.
2. 2.2. Determine the separation point on the C-pillar -B-  to the dimension -X= 18 mm-  . Mark the separation point.

→ Only separate parts using the oscillating body saw.

→ In the event of damage: Repair affected area by applying inert-gas welds.

1. 3.1. Cut through the outer hinge pillar at the marked separation point -A-  in the side member using the oscillating body saw. Do not damage the internal components.
2. 3.2. Cut through the outer hinge pillar at the marked separation point -B-  in the C-pillar using the oscillating body saw. Do not damage the internal components.

Information 

Separating body parts

• In the case of bonded panel joints with a hardened bonded layer on the outer panel, apply a generous amount of heat to heat up the outer panel in the area of the spotwelds.→  Diagram Of Body Bonding Points And Sealing Elements 
• After removing the loosened body part, old adhesive must be removed and any uneven spots sanded down. The flange area must then be pre-treated for bonding. For the procedure see: Information on the use of structural adhesive in vehicle manufacturing →  Information On The Use Of Structural Adhesives In Vehicle Construction 

1. 10.1. Heat up bonded joints between outer hinge pillar and hinge pillar reinforcement using the Leister Elektron hot-air gun   and remove outer hinge pillar.
