Flange Surface Installation Note
CAUTION:
- If the main silencer or TWC is reused, sand the flange surface and remove sanding residue, accumulated matter, and friction marks before installing the seal ring.
- If this work is not performed, the seal ring may not be installed correctly. When sanding the flange surface, be careful not to damage the surface.
- When sanding the flange surface, sanding residue may get into the removed part or pipe resulting in deterioration or damage the part. When sanding, make sure parts are protected from sanding residue or foreign matter penetration.
- Sand the surface shown below using sandpaper and remove the sanding residue, accumulated matter, and friction marks.
- Degrease the sanded surface.
