Precautions for Liquid GasketEBS011SZ
LIQUID GASKET APPLICATION PROCEDURE
1. Remove the old liquid gasket adhering to the gasket application surface and the mating surface.

Remove the liquid gasket completely from the gasket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating
use) to remove adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to the tube presser (special service
tool).
Use Genuine Liquid Gasket or equivalent.

Within five minutes of gasket application, install the mating com-
ponent.

If the liquid gasket protrudes, wipe it off immediately.

Do not retighten mounting bolts and nuts after the installation.

Wait 30 minutes or more after installation before filling the
