Seal Ring Removal Note

1. Remove the seal ring using a flathead screwdriver being careful not to damage the pipe.

A/F sensor, HO2S Removal Note

1. Remove the A/F sensor, HO2S using the SST.

Engine Mount Bracket (RH) Removal Note

1. Attach the SST and support the engine.

2. Remove the engine mount rubber (LH) installation nut.

Engine Mount Rubber (RH) Removal Note

1. Tighten the A part indicated in the figure, and then pull up the engine to remove the engine mount rubber (RH).

Main Silencer Installation Note

Caution

• If the main silencer and middle pipe are reused after being separated once, exhaust gas leakage will occur. When replacing the main silencer or middle pipe, always replace the main silencer and middle pipe at the same time.

1. Install the main silencer so that the stopper is at the position shown in the figure.

Exhaust Manifold Installation Note

Caution

• Do not reuse the gasket and self-lock nuts on the joint area between the engine and exhaust manifold.

• If a gasket with detached crimps is used on the joint area between the engine and exhaust manifold, exhaust gas will leak. Be careful not to allow the crimps to detach from the gasket. Do not use a gasket if any crimps are detached.

Seal Ring Installation Note

Caution

• 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.

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

2. Install the SST to the seal ring so that the SST is even with the flange.

3. Press in the seal ring by tapping the SST using a plastic hammer until the seal ring contacts the flange.
