3. Attach liquid gasket tube to the tube presser (SST).
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 5 minutes of liquid gasket application, install the mating
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 specific instructions in this manual, observe
them.

20. 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 for cracks and any excessive wear at link plates and roller
links of timing chain. Replace timing chain as 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
balancer unit mounting bolt with a new one.

Compress valve spring with valve spring compressor, attach-
ment and adapter (SST). Install valve collet with magnet
hand.
CAUTION:
When working, be careful not to damage valve lifter
holes.

Tap valve stem edge lightly with plastic hammer after installa-
tion to check its installed condition.
8. Install valve lifter.

Install it in the original position.
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 sealant all round on spark plug tube within approximately
12 mm (0.47 in) width from edge of spark plug tube on the
press-fit side.
Use Thread Locking Sealant or equivalent.
c. Using drift, press-fit spark plug tube so that height is as same as
“H” shown in the figure.
CAUTION:

When press-fitting, be careful not to deform spark plug tube.

After press-fitting, wipe off any protruding thread locking sealant 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-
109, "Valve Dimensions" .

If dimensions are out of the standard, replace valve.

2. Drive out valve guide with a press [under a 20 kN (2 ton, 2.2 US
ton, 2.0 lmp ton) force] or hammer and valve guide drift (com-
mercial service tool).
CAUTION:
Cylinder head contains heat, when working, wear protective
equipment to avoid getting burned.
3. Ream cylinder head valve guide hole with valve guide reamer
(commercial service tool).
4. Heat cylinder head to 110 to 130°C (230 to 266°F) by soaking in
heated oil.
5. Using valve guide drift (commercial service tool), 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 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. Refer to EM-75, "
VALVE SEAT REPLACE-
MENT" .
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-112, "
Va l v e S e a t" .
CAUTION:
Prevent to scratch cylinder head by excessive boring.
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 seat cooled well with dry ice. Press-fit valve seat into cylinder head.
CAUTION:

Avoid directly to touching cold valve seats.Standard

Cylinder head contains heat, when working, wear protective equipment to avoid getting burned.
5. Using valve seat cutter set (commercial service tool) or valve
seat grinder, finish valve seat to the specified dimensions. For
dimensions, refer to EM-112, "
Va l v e S e a t" .
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.
6. Using compound, grind to adjust valve fitting.
7. Check again for normal contact. Refer to EM-75, "
VALVE SEAT CONTACT" .
VALVE SPRING SQUARENESS

Set try square along the side of valve spring and rotate spring.
Measure the maximum clearance between the top face of spring
and try square.
CAUTION:
Do not remove valve spring seat from valve spring.

If it exceeds the limit, replace valve spring (with valve spring
seat).
VALVE SPRING DIMENSIONS AND VALVE SPRING PRESSURE LOAD

Check valve spring each load at specified spring height.
CAUTION:
Do not remove valve spring seat from valve spring.
Standard:

If the installation load or load with valve open is out of the standard, replace valve spring (with valve spring
seat).
