Seal Ring Installation Note

CAUTION:

If the TWC or main silencer 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.
If installation is performed without using the SST, the seal ring will be damaged and deformed, resulting in an incorrect installation. Always use the SST to install the seal ring.

Temporarily install the seal ring to the pipe so that the seal ring is even with the flange.
