PRECAUTIONS
Precautions For Liquid Gasket
EBS00MRW
REMOVAL OF LIQUID GASKET
●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-blade
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 the liquid gasket to the tube presser.
Use Genuine Liquid Gasket or equivalent.
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. If specified, it should be applied outside the holes.
Make sure to read the instruction in 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 instructions in this manual, observe them.

5. Install valve spring.
●Install smaller pitch (valve spring seat side) to cylinder head
side.
●Confirm identification color of valve spring.
6. Install valve spring retainer.
7. Install valve collet.
●Compress valve spring with valve spring compressor. Install
valve collet with magnet hand.
●Tap stem edge lightly with plastic hammer after installation to check its installed condition.
8. Install valve lifter.
9. Install spark plug tube.
●Press fit it into cylinder head as follows.
a. Remove old liquid gasket from cylinder head side mounting
hole.
b. Apply liquid gasket all round on spark plug tube with a 12 mm
(0.47 in) width from edge of spark plug tube on the press fit side.
Use Genuine Liquid gasket or equivalent.
c. Using a drift (commercial service tool), press fit spark plug tube
so that height is as same as H shown in figure.
CAUTION:
●When press fitting be careful not to deform spark plug tube.
●After press fitting, wipe off any protruding liquid gasket on top surface of cylinder head.
10. Install spark plug with spark plug wrench.

CYLINDER HEAD DISTORTION
1. Wipe off engine oil and remove water scale (like deposit), gas-
ket, sealer, carbon, etc with scraper.
CAUTION:
Use utmost care not to allow gasket debris to enter pas-
sages for engine oil or water.
2. At each of several locations on bottom surface of cylinder head,
measure distortion in six directions.
VALVE DIMENSIONS
Check dimensions of each valve. For dimensions, refer to SDS, EM-
99, "Valve Dimensions" . Intake : Blue
Exhaust : Yellow

5. Press valve guide from camshaft side to dimensions as in illus-
tration.
CAUTION:
Cylinder head contains heat, when working, wear protective
equipment to avoid getting burned.
6. Using valve guide reamer, apply reamer finish to valve guide.
VALVE SEAT CONTACT
●After confirming that the dimensions of valve guides and valves
are within specifications, perform this procedure.
●Apply prussian blue (or white lead) onto contacting surface of
valve seat to check the condition of the valve contact on the sur-
face.
●Check if the contact area band is continuous all around the cir-
cumference.
●If not, grind to adjust valve fitting and check again. If the contact-
ing surface still has NG conditions even after the re-check,
replace valve seat.
VALVE SEAT REPLACEMENT
When valve seat is removed, replace with oversized [0.5 mm (0.020 in)] valve seat.
1. Bore out old seat until it collapses. Boring should not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this.
2. Ream cylinder head recess diameter for service valve seat.
●Be sure to ream in circles concentric to the valve guide center.
This will enable valve seat to fit correctly.

3. Heat cylinder head to 110 to 130°C (230 to 266°F) by soaking in
heated oil.
4. Provide valve seats cooled well with dry ice. Force fit valve seat
into cylinder head.
CAUTION:
●Avoid directly to touching cold valve seats.
●Cylinder head contains heat, when working, wear protec-
tive equipment to avoid getting burned.
5. Using valve seat cutter set or valve seat grinder, finish the seat
to the specified dimensions.
CAUTION:
When using valve seat cutter, firmly grip the cutter handle
with both hands. Then, press on the contacting surface all
around the circumference to cut in a single drive. Improper
pressure on with the cutter or cutting many different times
may result in stage valve seat.
●Grind to obtain the dimensions indicated in figure.
6. Using compound, grind to adjust valve fitting.
7. Check again for normal contact.
VALVE SPRING SQUARENESS
Set try square along the side of valve spring and rotate the spring.
Measure the maximum clearance between the top face of spring and
try square.
