Installing a Reinforcement Plate
- Straighten the area where the
reinforcement plate will be installed using cold methods. NoteDo not use heat methods to straighten webbing sections.
- Cut a section of
reinforcement plate to length.NoteReinforcement plates are placed on both sides of cracked or straightened webbing. Make sure that each reinforcement plate covers the maximum surface area around the repair area.
- Trim and rework the reinforcement plate as necessary to snugly fit over the area to be reinforced, and allow for any adjoining panels.
- Remove any contaminants from the mating surfaces on the repair area and the reinforcement plate by cleaning them with isopropyl alcohol (IPA) prior to applying structural adhesive.
- Apply structural adhesive.
- Fit the reinforcement plates into position and clamp them into place.
- Wipe off excess structural adhesive.
Replacing a Damaged Stud
A damaged or broken stud may be replaced using a double-ended stud (Tesla part number 1463292-00-C).
To replace a broken stud:
- Grind down the damaged stud until it is flush with the surrounding material.
- Use a center punch to mark the center of the remaining part of the stud (the location of the replacement stud).
- Drill a 5.5 mm. hole that is 22 mm. deep in the replacement stud location.
- Remove all debris from the drilled hole.
- Insert the self-tapping double ended stud and torque it to 5 Nm.
