LIQUID GASKET APPLICATION PROCEDURE

Using a scraper (A), remove old liquid gasket adhering to the liq-
uid gasket application surface and the mating surface.
• Remove liquid gasket completely from the groove of the liquid

gasket application surface, mounting bolts, and bolt holes.

Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.

Attach liquid gasket tube to the tube presser (commercial ser-
vice tool).
Use Genuine Liquid Gasket or equivalent.

Apply liquid gasket without gaps to the specified location accord-
ing to the specified dimensions.
• If there is a groove for liquid gasket application, apply liquid

gasket to the groove.

• As for bolt holes

, normally apply liquid gasket inside the

holes. Occasionally, it should be applied outside the holes.
Check to read the text of this manual.

• Within five minutes of liquid gasket application, install the mat-

ing component.

• If liquid gasket protrudes, wipe it off immediately.
