CYLINDER HEAD
3. Ream cylinder head valve guide hole using suitable tool (A).
4. Heat cylinder head to 110
° to 130° C (230° to 266° F) by soaking
in heated oil (A).
5. Press valve guide (1) from camshaft side to dimensions as shown.
WARNING:
Cylinder head contains heat, when working, wear protective
equipment to avoid getting burned.
6. Apply reamer finish to valve guide using suitable tool (A).
VALVE SEAT CONTACT
• After confirming that the dimensions of valve guides and valves are within specifications, perform this proce-
dure.
• Apply prussian blue (or white lead) onto contacting surfac e of valve seat to check the condition of the valve
contact on the surface. Valve guide hole diameter (for service parts):
: 9.675 - 9.696 mm (0.3809 - 0.3817 in)

• 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.
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 shoul d not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this. Refer to EM-223, "
Standard and Limit".
2. Ream cylinder head (1) 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 (A).
4. Use dry ice to thoroughly cool valve seats. Press-fit valve seat into cylinder head. WARNING:
• Never touch cold valve seats directly.
• Cylinder head contains heat, wh en working, wear protective equipment to avoid getting burned.
5. Using valve seat cutter set or valve seat grinder, finish valve seat to the specified dimensions. For dimensions, refer to EM-
223, "Standard and Limit".
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 cu t in a single drive. Improper
pressure on the cutter or cutting many different times may
result in staged valve seat.
6. Using compound, grind to adjust valve fitting.
7. Check again for normal 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:
Never 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:
Never 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 springseat). Limit: 1.9 mm (0.075 in)

CAUTION:
• Avoid impacts such as a dropping.
• Never disassemble.
• Keep it away from metal particles.
• Never place sensor in a location wher
e it is exposed to magnetism.
8. Remove oil filter (for intake valve timing control).
9. Remove pilot converter (1) using Tool (A). (A/T or CVT models)
NOTE:
M/T models have no pilot converter.
10. Position crankshaft pin corresponding to connecting rod to be removed onto the bottom dead center. NOTE:
Before removing piston and connecting rod assembly, check the connecting rod side clearance. Refer to
EM-212, "
Inspection After Disassembly".
11. Remove connecting rod cap.
12. Using a suitable tool, push piston and connecting rod assembly out to the cylinder head side.
CAUTION:
• Be careful not to damage matching surface with connect-ing rod cap.
• Be careful not to damage the cylinder wall and crankshaft pin, resulting from an inte rference of the connecting rod
big end.
13. Remove connecting rod bearings. CAUTION:
When removing them, note the installation position. Keep them in the correct order.
14. Remove piston rings from piston. • Before removing piston rings, check the piston ring side clearance. Refer to EM-212, "
Inspection After
Disassembly".
15. Using a suitable tool (A) remove piston rings. CAUTION:
• When removing piston rings, be careful not to damage thepiston.
• Be careful not to damage piston rings by expanding them excessively.Tool number :ST16610001 (J-23907)

• Measure the outer diameters [(d1), (d2)] at two positions as shown.
• If reduction appears in places other than (B) range, 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 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) exceeds the limit (when it becomes thinner), replace
connecting rod bolt with a new one.
CLOGGED OR DAMAGED OIL FILTER (FOR INTAKE VALVE TIMING CONTROL)
• Make sure that there is no foreign material on the oil filter and
check it for clogging.
- Clean it if necessary.
• Check the oil filter for damage.
- Replace it if necessary.

dial indicator (A).
• Measure the deflection at 210 mm (8.27 in) diameter.
• If measured value is out of the standard, replace flywheel.
• If a trace of burn or discolorati on is found on the surface, repair it
with sandpaper.
CAUTION:
When measuring, keep magnetic fields (such as dial indicator
stand) away from signal plate of the rear end of crankshaft.
MOVEMENT AMOUNT OF FLYWHEEL (M/T MODELS)
CAUTION:
Never disassemble double mass flywheel.
Movement Amount of Thrust (Fore-and-Aft) Direction
