Precautions For Liquid Gasket
EBS00SJK
REMOVAL AND LIQUID GASKET
●
After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter and remove the liquid gasket.
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 gasket applied area.
CAUTION:
If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating sur-
faces.
LIQUID GASKET APPLICATION PROCEDURE
1.
Using a scraper, remove the old liquid gasket adhering to the
gasket application surface and the mating surface.
●
Remove the liquid gasket completely from the groove of the
gasket application surface, mounting bolts, and bolt holes.
2.
Wipe the gasket application surface and the mating surface with
white gasoline (lighting and heating use) to remove adhering
moisture, grease and foreign materials.
3.
Attach the liquid gasket to the tube presser.
Use Genuine Liquid Gasket or equivalent.
4.
Apply the gasket without breaks to the specified location with the
specified dimensions.
●
If there is a groove for the liquid gasket application, apply the
gasket to the groove.
●
As for the bolt holes, normally apply the gasket inside the
holes. Occasionally, it should be applied outside the holes.
Make sure to read this service manual.
●
Within five minutes of gasket application, install the mating
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 coolant.
CAUTION:
If there are specific instructions in this service manual, observe
them.
