PRECAUTIONS

Precautions for Liquid GasketEBS00MRW
REMOVAL OF LIQUID GASKET

After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter (special service tool) and remove the
old liquid gasket sealing.
CAUTION:
Be careful not to damage the mating surfaces.

In areas where seal cutter (special service tool) is difficult to use,
use a plastic hammer to lightly tap (1) seal cutter where the liq-
uid gasket is applied. Use a plastic hammer to slide seal cutter
(2) by tapping on the side.
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 liquid gasket tube to the tube presser (special service
tool).
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. Occasionally, it should be applied outside the
holes. Make sure to read the text of service 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 mounting bolts or nut after the installation.

Wait 30 minutes or more after installation before refilling
engine oil and engine coolant.
CAUTION:
If there are instructions in this manual, observe them.

TIMING CHAIN

a. Lift lever up, and release ratchet claw for return proof.
b. Push tensioner sleeve in, and hold it.
c. Matching the hole on lever with the one on body, insert a stopper
pin to secure tensioner sleeve.
NOTE:
Use approximately 1 mm (0.04 in) dia. hard metal pin as a stop-
per pin.
d. Remove balancer unit timing chain tensioner.
21. Remove balancer unit timing chain and crankshaft sprocket.
22. Loosen mounting bolts in reverse order as shown in the figure,
and remove balancer unit.
CAUTION:
Do not disassemble balancer unit.
NOTE:
Use TORX socket (size E14).
INSPECTION AFTER REMOVAL
Timing Chain
Check timing chain for cracks and any excessive wear at the roller
links of timing chain. Replace timing chain if necessary.
Balancer Unit Mounting Bolt Outer Diameter

Measure the outer diameters (“d1” , “d2” ) at two positions as
shown in the figure.

If reduction appears in “A” range, regard it as “d2 ”.

If it exceeds the limit (large difference in dimensions), replace it
with a new one.

Compress valve spring with a valve spring compressor,
attachment and adapter (special service tool). Install valve
collet with a magnet hand.
CAUTION:
When working, be careful not to damage valve lifter
holes.

Tap valve stem edge lightly with a plastic hammer after instal-
lation to check its installed condition.
8. Install valve lifter.
9. Install spark plug tube if removed.

Press-fit it into cylinder head with the following procedure:
a. Remove old liquid gasket from cylinder head side installation
hole.
b. Apply liquid gasket all round on spark plug tube within approxi-
mately 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, 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 (commercial service tool).

VALVE DIMENSIONS

Check dimensions of each valve. For dimensions, refer to EM-
11 0 , "Valve Dimensions" .

If dimensions are out of the standard, replace valve.

4. Heat cylinder head to 110 to 130°C (230 to 266°F) by soaking in
heated oil.
5. Press valve guide from camshaft side to dimensions as shown
in the figure.
CAUTION:
Cylinder head contains heat, when working, wear protective
equipment to avoid getting burned.
6. Apply reamer finish to valve guide with a valve guide reamer
(commercial service tool).
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. Refer to EM-113, "
Va l v e S e a t" .
