Sectioning Guidelines

General sectioning guidelines:
  • It is allowable to cut through a clearance hole or a non functional hole (exterior trim hole).
  • Do not cut within 25 mm. of the center of a bolt hole or stud.
  • Seal all open seams after structural adhesive has cured.
  • Sections do not require fasteners at butt joints unless specifically indicated.
  • A backing plate may be installed at a butt joint between sections (as described in create and install backing plates).
  • GMA weld section butt joints.
  • If a butt joint includes a flange, do not weld on the flange (flanges are secured using only structural adhesive).

The image below shows the Wheelhouse Outer (complete). The colored areas indicate if sectioning is allowed. Compare the damaged area of the vehicle's Wheelhouse Outer to the image below, then use the repair criteria corresponding to the color of the highlighted area to find the criteria to use to determine if the damaged area of the component can be sectioned.

Wheelhouse Outer Sectioning

Based on the colors used in the image above, the allowed repairs are as follows:

Table 1. Allowed Sectioning
Area Color Area Repairability
Green areas: Sectioning is allowed in these areas.

Overlap joints must have at least a 25 mm. of overlap that is secured with structural adhesive. When using an overlap joint between a red zone area and a green zone area, the red zone area must overlap into the green zone area 25 mm. or more (do not overlap into the red zone).

Yellow areas: Sectioning is allowed in these areas.
Informational PurposesAn informational icon, calling your attention
Note
Sectioning in these areas requires the component be returned to its original geometry for proper function.

Overlap joints must have at least a 25 mm. of overlap that is secured with structural adhesive. When using an overlap joint between a red zone area and a yellow zone area, the red zone area must overlap into the yellow zone area 25 mm. or more (do not overlap into the red zone).

Areas shown in yellow include areas that:

  • Allow water ingress, so use special care to make sure that seals fit correctly in all repaired areas.
