VALVE GUIDE CLEARANCE
Valve Stem Diameter
Measure the diameter of valve stem with micrometer.
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 it exceeds the limit, replace valve guide and/or valve. When valve guide must be replaced, refer to EM-
73, "VALVE GUIDE REPLACEMENT" .

mercial service tool).
CAUTION:
Cylinder head contains heat, when working, wear protective
equipment to avoid getting burned.
3. Ream cylinder head valve guide hole with valve guide reamer
(commercial service tool).
4. Heat cylinder head to 110 to 130°C (230 to 266°F) by soaking in
heated oil.
5. Using valve guide drift (commercial service tool), press valve
guide from camshaft side to dimensions as shown in the figure.

6. Apply reamer finish to valve guide with valve guide reamer
(commercial service tool).
VALVE SEAT CONTACT

After confirming that the dimensions of valve guides and valves
are within 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 sur-
face.

Check if the contact area band is continuous all around the cir-
cumference.

If not, grind to adjust valve fitting and check again. If the contact-
ing surface still has NG conditions even after the re-check,
replace valve seat. Refer to EM-75, "
VALVE SEAT REPLACE-
MENT" .
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 should not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this. Refer to EM-112, "
Va l v e S e a t" .
CAUTION:
Prevent to scratch cylinder head by excessive boring.
2. Ream cylinder head 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.
4. Provide valve seat cooled well with dry ice. Press-fit valve seat into cylinder head.
CAUTION:

Avoid directly to touching cold valve seats.Standard

INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.

Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

Use procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.

Run engine to check for unusual noise and vibration.

Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.

Bleed air from lines and hoses of applicable lines, such as in cooling system.

After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
