Quarter Outer Assembly (Without Upper Trough)

Repair Information

Note

If the repair area includes any portion of the Roof Rail, do not use this procedure; instead, refer to the Body Side Outer.

Any individual section or any combination of sections of the Body Side Outer Assembly can be replaced so long as the referenced cut lines from the Quarter Outer Assembly Section Descriptions portion of this document are used.
Review all collision repair general practices and safety documentation and wear the appropriate PPE (Personal Protective Equipment) before beginning this procedure.
This procedure can be completed without using a frame bench.

Using this Document

This document contains two major parts:

Quarter Outer Assembly Section Descriptions provides information on where and how to section the Quarter Outer Assembly (or subassemblies) as necessary to replace damaged areas of the Quarter Outer assembly, or to gain access to underlying parts of the vehicle structure. Use the section descriptions to determine where to successfully section the Body Side Outer Assembly as needed for the repair being performed.
Note
Sections of the Quarter Outer Assembly can be replaced individually or in any combination of sections so long as the referenced cut locations identified in this document are used.
Note
Measurements from bolt hole locations are from the center of the referenced holes unless stated differently in the section description.
The Repair Procedure portion of this document contain the information necessary to replace the entire Quarter Outer Assembly. If replacing sections of the Quarter Outer (not the entire Quarter Outer Assembly), use the relevant portions of each step to determine which parts and fasteners are needed and the steps required to complete the repair.

Quarter Outer Assembly Section Descriptions


Quarter Outer Assembly Sectioning
The Quarter Outer Assembly is a single assembly, and can be replaced as a single repair, or instead of replacing the complete Quarter Outer Assembly, areas of the Quarter Outer can be replaced using portions of the complete Quarter Outer Assembly using the cut lines described in this document.


Quarter Outer Section Descriptions	Joint Descriptions
Quarter Outer Skin Section Reference Line/Point Cut Line A = 77 mm B = 163 mm C = 33 mm D = 146 mm Note Refer to the Body Side Outer procedure for sectioning guidelines. GMA Weld Note The gap between the adjacent panels of the butt joint for this section should be as small as possible to maximize joint strength.
Rear Sill Section Reference Line/Point Cut Line E = 165 mm F = 412 mm Note Refer to the Body Side Outer procedure for sectioning guidelines. GMA Weld Note The gap between the adjacent panels of the butt joint for this section should be as small as possible to maximize joint strength.
Dogleg Section Reference Line/Point Cut Line G = 118 mm H = 76 mm Note Refer to the Body Side Outer procedure for sectioning guidelines. GMA Weld Note The gap between the adjacent panels of the butt joint for this section should be as small as possible to maximize joint strength.
Rear Roof Rail Section Note If the repair area includes any portion of the Roof Rail, do not use this procedure; instead, refer to the Body Side Outer procedure.

Repair Procedure

Remove the Upper Trough from the Rear Quarter Outer Assembly service part.
or Factory Spot Welds
or Drill through factory spot welds
Note
When drilling out spot welds, use a drill bit that creates a hole correctly sized for the fastener that will replace the spot weld.
Remove the original component.
or Factory Spot Welds
or Factory SPRs

or Drill through factory spot welds
Note
When drilling out spot welds, use a drill bit that creates a hole correctly sized for the fastener that will replace the spot weld.
Prepare for installation.

Note
A red X indicates a location where a factory-installed fastener is not being replaced.

or Installation Spot Welds

or Steel Plug Welds

GMA Weld

or Structural Bulb Rivets, 6.5 mm

or Flow Form Rivets, S18
Apply structural adhesive to the mating surfaces on the vehicle and the new component or components.
Install the new component or components.
Perform resistance spot welding.

Warning
Failure to follow all welding safety precautions, including the use of personal protective equipment, could result in serious injury or property damage. Only technicians who have completed Tesla’s approved welding training are authorized to weld structural components on Tesla vehicles.

CAUTION
Do not weld on a Tesla vehicle before performing the Vehicle Electrical Isolation Procedure (refer to the vehicle-specific Service Manual for more information on the Vehicle Electrical Isolation Procedure). Welding on a Tesla vehicle with an energized high or low voltage system might damage vehicle components.
Perform GMA welding.
or Steel Plug Welds
GMA Weld

Warning
Failure to follow all welding safety precautions, including the use of personal protective equipment, could result in serious injury or property damage. Only technicians who have completed Tesla’s approved welding training are authorized to weld structural components on Tesla vehicles.

Warning
To maintain vehicle crash integrity, use only approved welding wire and an approved GMA welder to perform GMA welding on Tesla vehicles. Refer to Approved Gas Metal Arc (GMA) Welders and Welding Wire for information on approved GMA welders and welding wire.

CAUTION
Do not weld on a Tesla vehicle before performing the Vehicle Electrical Isolation Procedure (refer to the vehicle-specific Service Manual for more information on the Vehicle Electrical Isolation Procedure). Welding on a Tesla vehicle with an energized high or low voltage system might damage vehicle components.

Note
Before GMA welding, a test weld using material of the same gauge and type should be performed to make sure that the welding equipment settings produce a satisfactory joint.
Perform any necessary post-repair operations.
