VALVE GUIDE REPLACEMENT" to removal.
ASSEMBLY
1. Install valve guide if removed. Refer to EM-77, "VALVE GUIDE REPLACEMENT" .
2. Install valve seat if removed. Refer to EM-79, "
VALVE SEAT REPLACEMENT" .
3. Install valve oil seal.

Install with a valve oil seal drift (special service tool) to match
dimension in the figure.
NOTE:
Dimension “H” is height that measured before installing valve
spring (with valve spring seat).
4. Install valve.

5. Install valve spring (with valve spring seat).

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 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 thread locking sealant from cylinder head side
installation hole.
b. Apply thread locking 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 Genuine Thread Locking Sealant 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 thread locking sealant on top surface of cylinder
head.

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-121, "
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-79, "
VALVE SEAT CONTACT" .
VALVE SPRING SQUARENESS

Set try square along the side of valve spring and rotate the
spring. Measure the maximum clearance between the top of
valve 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 pressure with valve spring seat installed at
the 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).

MAIN BEARING CRUSH HEIGHT

When lower cylinder block is removed after being tightened to
the specified torque with main bearings installed, the tip end of
bearing must protrude. Refer to EM-94, "
ASSEMBLY" for the
tightening procedure.

If the standard is not met, replace main bearings.

ened to the specified torque with connecting rod bearings
installed, the tip end of bearing must protrude. Refer to EM-94,
"ASSEMBLY" for the tightening procedure.

If the standard is not met, replace connecting rod bearings.
LOWER CYLINDER BLOCK MOUNTING BOLT OUTER DIAMETER

Perform only with M10 bolts.

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 (a large difference in dimensions), replace
lower cylinder block mounting bolt with a new one.
CONNECTING ROD BOLT OUTER DIAMETER

Measure the outer diameter “d” at position as shown in the fig-
ure.

If reduction appears in a position other than “d”, regard it as “d”.

When “d ” exceeds the limit (when it becomes thinner), replace
