Cast Rear Under Body Repair Guidelines
Explains how to determine if the cast Rear Under Body can be repaired or if replacement is required.
The criteria to determine if a cast Rear Under Body component is repairable or if the Rear Under Body must be replaced are based on both the severity and the location of the damage. Use the images and information below to determine if the Rear Under Body component may be repaired or if replacement is required.
Based on the colors used in the images above, the allowed repairs are as follows:
Area Color | Allowed Repairs |
---|---|
Blue areas: |
|
Green areas: |
Note
Contact Tesla Collision Repair if there
are concerns about the number or width of discontinuities in the
component. |
Yellow areas: |
|
Orange areas: |
|
Red areas: |
None; if the Rear Under Body is damaged in these areas, contact Tesla Collision Repair for assistance. Note A broken
stud may replaced with a double ended stud. See Replacing a Damaged Stud for more
information. Warning Welding is
not allowed in this area. |
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:
- Cut the self tapping portion of the replacement stud to 11 mm. and remove any burrs from the cut end.
- 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 12 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. (The collar should be flush with the surface of the Rear Under Body.)
- Cut the protruding portion of the stud to approximately 11 mm. in height to properly fit the clip.
