General Sectioning Procedure
Important: Sectioning should take place only in recommended areas. Failure to do so may
compromise the structural integrity of the vehicle.
Important: This procedure does not apply to the front hinge pillar. See front hinge pillar
sectioning procedures.
• | When sectioning the door frame opening in areas where there is no inner
reinforcement, a 100 mm (4 in) backing plate must be used behind the
joint to ensure a solid and secure weld |
• | Backing plates can be cut from the unused portion of the door frame opening
service part. |
• | The specific areas to be sectioned are determined by the extent of damage
to the vehicle. |
Removal Procedure
Caution: Refer to Approved Equipment for Collision Repair Caution in the Preface section.
- Disable the SIR system. Refer to
SIR Disabling and Enabling
in SIR.
- Disconnect the negative battery cable. Refer to
Battery Negative Cable Disconnection and Connection
in Engine Electrical.
- Remove all related panels and components.
- Visually inspect and repair as much of the damage as possible to factory
specification.
Caution: Refer to Foam Sound Deadeners Caution in the Preface section.
- Note the location and remove the sealers and anti-corrosion materials
from the repair area, as necessary. Refer to
Anti-Corrosion Treatment and Repair
in Paint and Coating.
- Measure and compare the service part with the damaged part to choose the
areas where sectioning can best be performed.
- Cut the door frame opening where sectioning is to be performed. Do not
damage the inner panels or reinforcements.
Important: Do not damage any inner panels or reinforcements.
- Locate, mark, and drill out all factory welds. Note the number and location
of welds for installation of the service part.
- Remove the damaged area of the door frame opening.
Installation Procedures
- On the service part, mark a horizontal line to leave a gap of one and
one-half times the thickness of the metal at the sectioning joint.
- Cut the outer door frame opening service part along this line.
- Cut a 100 mm (4 in) piece from the unused portion of the
service part for a backing plate.
- Remove the flange on each side of the backing plate so that it will fit
behind the sectioning joint.
- Drill 8 mm (5/16 in) holes for plug welding in the service
part in locations noted from the original panel.
- Drill holes for plug welding along the sectioning cuts on both the service
part and the original panel.
- Locate these holes approximately 25 m (1 in) from the edge
of the sectioning cuts.
- Prepare mating surfaces and position the
backing plates with 50 mm (2 in) of the backing plate exposed, and
plug weld.
- Apply 3M® Weld-Thru coating P/N 05916 or equivalent to all
mating surfaces
- Position the service part to overlap the exposed 50 mm (2 in)
of the backing plate.
- Use three-dimensional measuring equipment to inspect the fit. Refer to
Dimensions - Body
.
- Plug weld accordingly.
- Stitch weld along the sectioning joint.
- Make 25 mm (1 in) welds along the seam with 25 mm
(1 in) gaps between.
- Go back and complete the stitch weld. This will create a solid joint with
minimal heat distortion.
- Use frequent measurements to ensure accurate fit and alignment to adjacent
panels.
- Clean and prepare welded surfaces.
- Apply the sealers and anti-corrosion materials to the repair area, as
necessary. Refer to
Anti-Corrosion Treatment and Repair
in Paint and Coatings.
- Paint and repair the area. Refer to
Basecoat/Clearcoat Paint Systems
in Paint and Coatings.
- Install all related panels and components.
- Connect the negative battery cable. Refer to
Battery Negative Cable Disconnection and Connection
in Engine Electrical.
- Enable the SIR system. Refer to
SIR Disabling and Enabling
in SIR.
