CAMSHAFT
 Make sure that there is no foreign material on the oil filter (1) and
check it for clogging.
 Check the oil filter for damage.
 If there is some damage, replace the oil filter, the plug, and the
washer as a set.
Camshaft Runout
1. Put V-block on a precise flat table, and support No. 2 and 5 jour-
nals of camshaft.
CAUTION:
Never support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
four locations.
2. Set a dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the
camshaft runout on the dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.
Camshaft Cam Height
1. Measure the camshaft cam height with a micrometer (A).
2. If wear exceeds the limit, replace camshaft.

Be careful not to damage valve lifter holes.
5. Remove valve spring retainer, valve spring and valve spring seat. Refer to EM-82, "
Disassembly and
Assembly".
6. Remove valve oil seal with the valve oil seal puller [SST:
KV10107902] (A).
INSTALLATION
1. Apply new engine oil to valve oil seal joint surface and seal lip.
2. Press in valve oil seal to the height “H” shown with the valve oil
seal drift [SST: KV10115600] (A).

 Measure the diameter of valve stem with micrometer (A).
Valve Guide Inner Diameter Measure the inner diameter of valve guide with bore gauge.
Valve Guide Clearance (Valve guide clearance) = (Valve guide inner diameter) – (Valve
stem diameter)
 If the calculated value exceeds the limit, replace valve and/or valve guide. When valve guide must be
replaced, use “VALVE GUIDE REPLACEMENT”.
Valve Seat Contact
 After confirming that the dimensions of valve guides and valves are
within the 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 surface.
 Check if the contact area band is continuous all around the circum-
ference.
 If not, grind to adjust valve fitting and check again. If the contacting
surface still has “NG” conditions even after the re-check, replace
valve seat. Refer to EM-82, "
Disassembly and Assembly".
Valve Spring Squareness
 Set a try square (A) along the side of valve spring and rotate
spring. Measure the maximum clearance between the top of spring
and try square.
 If it exceeds the limit, replace valve spring.
Valve Spring Dimensions and Valve Spring Pressure Load
 Check the valve spring pressure at specified spring height.
 If the installation load or load with valve open is out of the stan-
dard, replace valve spring.
ASSEMBLY
1. When valve guide is removed, install it.
CAUTION:
Replace with oversize [0.2 mm (0.008 in)] valve guide.Standard : Refer to EM-125, "

a. Ream cylinder head recess diameter (a) for service valve seat.
 Be sure to ream in circles concentric to valve guide center.
This will enable valve to fit correctly.
b. Heat cylinder head to 110 to 130°C (230 to 266°F) by soaking in
heated oil (A).
c. Provide valve seats cooled well with dry ice. Force fit valve seat into cylinder head.
WARNING:
Cylinder head contains heat. Wear protective equipment to avoid getting burned.
CAUTION:
Avoid directly touching cold valve seats.
d. Using the valve seat cutter set (commercial service tool) or valve
seat grinder, finish seat to the specified dimensions. Refer to
EM-125, "
Cylinder Head".
CAUTION:
When using the valve seat cutter, firmly grip 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 cutter or cutting many different times may
result in stage valve seat.
e. Using compound, grind to adjust valve fitting.
f. Check again for normal contact. Refer to EM-82, "
Disassembly and Assembly".
3. Install valve oil seal.
 Install with the valve oil seal drift [SST: KV10115600] (A) to
match dimension as shown.
4. Install valve spring seat.
5. Install valve.
 Install larger diameter to intake side.For service parts: Oversize [0.5 mm (0.020 in)]

Never rotate crankshaft.
 Remove connecting rod cap and bearing, and using the scale on
the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
MAIN BEARING OIL CLEARANCE
Method by Calculation
 Install main bearings to cylinder block and main bearing cap, and tighten main bearing cap bolts to the spec-
ified torque. Refer to EM-101, "
Disassembly and Assembly".
 Measure the inner diameter of main bearing with a bore gauge.
(Bearing oil clearance) = (Main bearing inner diameter) – (Crank-
shaft main journal diameter)
 If the clearance exceeds the limit, select proper main bearing
according to main bearing inner diameter and crankshaft main
journal diameter to obtain the specified bearing oil clearance.
Refer to EM-119, "
MainBearing".
Method of Using Plastigage
 Remove engine oil and dust on crankshaft main journal and the surfaces of each bearing completely.
 Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
 Install main bearings to cylinder block and main bearing cap, and tighten main bearing cap bolts to the spec-
ified torque. Refer to EM-101, "
Disassembly and Assembly".
CAUTION:
Never rotate crankshaft.
 Remove main bearing cap and bearings, and using the scale on
the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.

 When main bearing cap is removed after being tightened to the
specified torque with main bearings installed, the tip end of bearing
must protrude. Refer to EM-101, "

 If the standard is not met, replace main bearings.
CONNECTING ROD BEARING CRUSH HEIGHT
 When connecting rod bearing cap is removed after being tightened
to the specified torque with connecting rod bearings installed, the
tip end of bearing must protrude. Refer to EM-101, "
Disassembly
and Assembly".
 If the standard is not met, replace connecting rod bearings.
MAIN BEARING CAP BOLT OUTER DIAMETER
 Measure the outer diameters (“d1”, “d2”) at two positions as shown
in the figure.
 If reduction appears in a position other than “d
2 ”, regard it as “d2”.
 If it exceeds the limit (a large difference in dimensions), replace
main bearing cap bolt with a new one.
CONNECTING ROD CAP BOLT OUTER DIAMETER
 Measure the outer diameter “d” at position as shown in the figure.
 If reduction appears in a position other than “d”, regard it as “d”.
 When “d” falls below the limit (when it becomes thinner), replace
connecting rod cap bolt with a new one.
