STRAIGHTENING ALUMINUM COMPONENTS IN STRUCTURE REP-ALG-RAGRP41-4105101_STRUKTUR - V.4 (Countryman 2017-2023, except PHEV)

• Reshaping or heating extruded profiles and cast parts is not permitted! 

  Failure to comply with this requirement would have the following results:

  In the case of reshaping, weld seams or bonded connections tear in the surrounding area.

  In the case of reshaping, the material loses up to 40 % of its original strength.

  In the case of heating, the material loses up to 40 % of its original strength.

  The adhesive is destroyed at temperatures ≥120 °C.

  Extruded profiles and cast parts which show visible or measurable signs of deformation must be replaced.

  Perform the check for deformation with the aid of the straightening system.

  For optical testing, strip adjoining components in cases of doubt.

  Extruded profiles are used as engine mounts, door pillars, side members, etc.

  Cast parts are used as spring supports or rear side members.

• Reshaping of extruded profiles and cast parts may only be used to achieve optimum joining of connection areas (e.g. when bulkhead is damaged). Reshaped parts must be replaced.
• Repairs which affect the attachment points of mechanical assemblies and chassis/suspension components must be carried out on the straightening bench. Use the vehicle-specific set of attachments set or vehicle-specific data sheet.

  Straightening attachment supports and data sheets are also available for the top section, e.g.: door pillars, soft top mounts, windshield panel, tailgate hinges, etc.

• Check windshield and rear window apertures for curvature by inserting the original glass.
• Take the gap dimensions for doors, hood and trunk lid from the vehicle-specific gap dimension diagram.
• Exceptions on the E60, E61, E63, E64:

  Carrier support and bulkhead may be straightened if they do not have any cracks, sharp-edged damage or holes. After repair work, check parts again for cracks.

  Examine adjoining adhesive flanges for peeling off. If necessary, seal and preserve with SEALANT .

  Observe the frame reference dimension for the carrier support.

Any repairs to the bulkhead if cracked outside the approved scope of repair work are only permitted after consultation with and approval by BMW. Should you have any questions, please contact the country-specific BMW hotline.
