Precautions For Liquid GasketEBS009S9
REMOVAL OF LIQUID GASKET
lAfter removing the mounting bolts and nuts, disconnect and
remove the liquid gasket using a seal cutter.
CAUTION:
Be careful not to damage the mating surfaces.
lIn areas where the cutter is difficult to use, use a plastic hammer
to lightly tap the gasket applied area.
CAUTION:
Ifforsomeunavoidablereasonatoolsuchasaflat-blade
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.
lRemove the liquid gasket completely from the groove of the gas-
ket 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.
lIf there is a groove for the liquid gasket application, apply the
gasket to the groove.
lAs for the bolt holes, normally apply the gasket inside the holes.
Occasionally, it should be applied outside the holes. Make sure
to read the instruction in this manual.
lWithin five minutes of gasket application, install the mating com-
ponent.
lIf the liquid gasket protrudes, wipe it off immediately.
lDo not retighten after the installation.
lAfter 30 minutes or more have passed from the installation, fill
the engine oil and coolant.
CAUTION:
If there are instructions in this manual, observe them.
