• 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. Install the valve guide, if necessary. CAUTION:
Replace with oversize [0.2 mm (0.008 in)] valve guide.
a. Using suitable tool (A), ream cylinder head valve guide hole.
b. Heat cylinder head to 110 to 130 °C (230 to 266 °F) by soaking in
heated oil (A). B : Contact

d. Using suitable tool or valve seat grinder, finish seat to the speci-
fied dimensions. Refer to EM-119, " Cylinder Head " .
CAUTION:
When using the valve seat cutt er, firmly grip cutter handle
with both hands. Then, press on the contacting surface all
around the circumference to cu t in a single drive. Improper
pressure on with cutter or cu tting 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 Tool (A) to match dimension as shown.
4. Install valve spring seat.
5. Install valve. • Install larger diameter to intake side.
6. Install valve spring. NOTE:
It can be installed in either direction.
7. Install valve spring retainer.
8. Install valve collet. • Compress valve spring with Tool (A). Install valve collet with amagnet hand (B).
CAUTION:
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.
9. Install valve lifter.
10. Install spark plug with a suitable tool. SEM934C

• 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-96, " 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-113, " Main Bearing " .
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-96, " 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”.
MAIN BEARING CRUSH HEIGHT • 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-96, " Disassembly and Assembly " .
• If the standard is not met, replace main bearings. Main Bearing " .

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-96, " Disassembly
and Assembly " .
• If the standard is not met, replace connecting rod bearings.
MAIN BEARING CAP BOLT OUTER DIAMETER
• Measure the outer diameters (“d 1”, “d 2”) at two positions as shown.
• If reduction appears in a position other than “d 2 ”, regard it as “d 2”.
• 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.
• 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.
FLYWHEEL DEFLECTION
• Measure the deflection of flywheel contact surface to clutch with a
dial indicator.
• If measured value is out of the standard, replace flywheel. Standard: There must be crush height. PBIC1646E
