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.
CONNECTING ROD BEARING CRUSH HEIGHT

When connecting rod bearing cap is removed after being tight-
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
connecting rod bolt with a new one.Standard: There must be crush height.

CAUTION:

When removing or installing, do not use such tools as an air impact wrench.

Handle it carefully without giving any impact, even after removal. [As a guide, if it drops from
height of 10 cm (3.94 in) or higher, always replace it.]
INSTALLATION
1. Remove adhered carbon from glow plug installation hole with a reamer.
2. Install glow plug.
3. Install remaining parts in the reverse order of removal.

Loosen the camshaft sprocket mounting bolt by fixing the hex-
agonal portion of camshaft.
10.11. Remove camshaft as follows:
a. Loosen and remove the camshaft sprocket bolts in reverse order
shown in the figure.
b. Place distinguishing marks on the right and left sides with paint.
12. Remove adjusting shim and valve lifter.

Remove by taking notice of the installation position, and place outside engine in order to prevent confu-
sion.
INSPECTION AFTER REMOVAL
Visual Check of Camshaft

Check the camshaft for one sided wear or scratches.

Replace the camshaft if there are abnormalities.
Camshaft Runout

Prepare V-block on a flat surface and secure camshaft journals
No. 2 and No. 5.

Set the dial indicator vertically on journal No. 3.

Rotate camshaft in one direction by hand, then read needle
movement on dial indicator (total indicator reading).

If it exceeds the limit, replace camshaft.
Camshaft Cam Height

Measure the height of camshaft cam using the micrometer.

If out of the standard, replace camshaft.

Remove cylinder head bolts in reverse order as shown in the
figure with the cylinder head bolt wrench (commercial service
tool).

Lift up cylinder head assembly to avoid interference with
dowel pins located between the cylinder block and cylinder
head, and remove cylinder head assembly.
CAUTION:
Remove glow plug in advance to avoid damage as the tip
of the glow plug projects from the bottom of cylinder
head, or, place wood blocks beneath both ends of cylin-
der head to keep the cylinder bottom from any contact.

For glow plug removal, the following shall be noted.
CAUTION:

To avoid breakage, do not remove glow plug unless necessary.

Perform continuity test with glow plug installed.

Keep glow plug from any impact. [Replace if dropped from a height 10 cm (3.94 in) or higher.]

Do not use air impact wrench.
4. Remove cylinder head gasket.
INSPECTION AFTER REMOVAL
Cylinder Head Bolt Deformation

Using micrometer, measure the outer diameters “d1” and “d2” of
bolt thread as shown in the figure.

If the necking point can be identified, set it as measuring point
“d1”.

Calculate the difference between “d1” and “d2”.

If it exceeds the limit, replace cylinder head bolt.
Cylinder Head Distortion
NOTE:
When performing this inspection, cylinder block distortion should be also checked. Refer to EM-249, "
CYLIN-
DER BLOCK TOP SURFACE DISTORTION" .
1. Wipe off oil and remove water scale (like deposit), gasket, sealer, carbon, etc. with scraper.
CAUTION:
Use utmost care not to allow gasket debris to enter passages for oil or water.
2. At each of several locations on bottom surface of cylinder head,
measure distortion in six directions.

If it exceeds the limit, replace cylinder head.
