POSITION OF SHAPED PARTS FOR CAVITY SEALING

Cavity sealing is carried out in specific body areas in order to reduce interior noise and to reduce condensation.

To do this, shaped parts are inserted in the cavities. These shaped parts adapt themselves optimally due to heating of the body to approx. 180ºC by expansion to the shape of the cavities.

Because it is not possible to heat the body to this extent for a body repair, a different procedure has been specified for this situation.

Punch Rivets

The "Bonding and Riveting" repair method involves the use for the first time of punch rivets in the repair. This requires new tools and procedures.

The punch rivets are matched in size to the material thickness and quality used at the respective connection point.

1.0 Recommended tools and equipment

• Punch rivet tool (see Service Information 05 03 09 (535) )

Setting punch rivets

• Refer to the vehicle-specific repair instructions for the punch rivet size.
• Mark the positions of the rivets on the vehicle. Set punch rivets at roughly equal spacings.

  Punch rivets do not require a predrilled hole. They are pressed directly into the full material.

• Insert punch rivet in riveting die. Position punch rivet tool on sheet metal parts to be riveted.

  Riveting direction:
  Always from new part to used part.

  Deviations are specified in the vehicle-specific repair instructions.

• Rivet punch rivets with punch rivet tool. In the meantime clean riveting die and matrix if fouled with adhesive.
• Seal punch rivets in moist area (e.g. wheel arch or carrier support) on both sides with SEALANTD1 (risk of corrosion).
• Seal cavities after painting vehicle with CAVITY SEALANT (risk of corrosion).

QUALITY STANDARD

• The overall requirements relating to a vehicle can only be implemented by including "all" components.

  This applies in particular to the body. With regard to an optimum crash result, it is necessary to maintain the structural measures.

  It is absolutely essential to observe the procedures set out in the repair instructions. Any deviation from these procedures will only be permitted after prior consultation with and approval by BMW. Should you have any questions, please contact the country-specific Hotline.

  The use of non-approved repair steps or tools may have serious consequences for the structure of the vehicle (e.g. in the event of a crash). In the end, this can result in safety and product liability risks which cannot be calculated.

  Corrosion protection measures during and after repairs are absolutely essential to maintain the value of the vehicle.

• Use only genuine BMW parts and approved auxiliary devices, materials and operating fluids when carrying out repairs.
