Precautions for Liquid Gasket
EBS0024R
REMOVAL OF LIQUID GASKET SEALING
●
After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter and remove the old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.
●
In areas where the cutter is difficult to use, use a plastic hammer
to lightly tap the areas where the liquid gasket is applied.
CAUTION:
If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating
surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1.
Using a scraper, remove the old liquid gasket adhering to the liq-
uid gasket application surface and the mating surface.
●
Remove the liquid gasket completely from the groove of the
liquid gasket application surface, mounting bolts, and bolt
holes.
2.
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.
3.
Attach genuine liquid gasket tube to the tube presser.
Use Genuine Thread sealant or equivalent. Refer to
"RECOMMENDED CHEMICAL PRODUCTS AND SEAL-
ANTS"
4.
Apply the liquid gasket without breaks to the specified location
with the specified dimensions.
●
If there is a groove for the liquid gasket application, apply the
liquid gasket to the groove.
●
As for the bolt holes, normally apply the liquid gasket inside
the holes. Occasionally, it should be applied outside the
holes. Make sure to read the text of this manual.
●
Within five minutes of liquid gasket application, install the mat-
ing component.
●
If the liquid gasket protrudes, wipe it off immediately.
●
Do not retighten after the installation.
●
After 30 minutes or more have passed from the installation, fill
the engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe
them.
