Repair Information
- 只要使用本文档中 后轮拱区块说明 部分指定的参考切割线，即可更换车身侧外件总成的任何一个区块或多个区块的任意组合。
- 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.
使用本文档
- 后轮拱区块说明 说明需要时分割后轮拱和位置和方法，以便更换后轮拱损坏区域，或者为车辆结构底部零件留出操作空间。对照参考区块说明判定在维修时根据需要成功分割后轮拱的位置。注对螺栓孔位置的测量应以参考孔洞的中心为起点，除非区块说明中有不同的表述。
- 本文档的“维修程序”部分提供了更换整个后轮拱所需的信息。如需更换后轮拱的某个区块（非整个后轮拱），请参考各步骤的相关部分确定需要哪些零件和紧固件以及完成维修所需的步骤。

 Cut Line
注 在车辆上切割线前方 25 毫米处切割新的后轮拱维修零件，以制作与仍在车辆上的组件有搭接接头的新组件。 注 如图所示，切割上部和下部对接接头的切口，并根据需要进行修剪，以获得良好的对接接头。 注 A red X indicates a location where
a factory-installed fastener is not being replaced.
 or SPRs, 5x6 H4
注 安装此 SPR 需要使用以下 Tesla SPR 模具：SM 085 0125。

更换后轮拱的一个区块：
采用 GMA 焊接法焊接区块之间的对接接头。
GMA Weld
警告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.警告To maintain vehicle crash integrity, use only approved welding wire and an approved GMA welder to perform GMA welding on Tesla vehicles. Refer to 已批准的气体保护金属极弧 (GMA) 焊接器和焊丝 for information on approved GMA welders and welding wire.警告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.注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. - 更换后轮拱的一个区块：将 GMA 焊缝的外表面打磨平整，使上面的组件能齐平安装。
