8. If necessary, follow the procedure below and remove the guide.
a. Heat cylinder head to 110 – 130
°
C by soaking it in heated oil.
b. Drive out the valve guide from combustion chamber side using a
valve guide drift (commercial service tool: for inner diameter
φ
5.0 mm).
CAUTION:
Use protective gloves so as to prevent burns because the

c. Using a valve guide drift (commercial service tool: for inner
diameter
φ
5.0 mm), press-fit valve guide (1) from camshaft side
so that the valve guide installation height is dimension H, as
shown in the figure.
CAUTION:
Use protective gloves for preventing burns because the cyl-
inder head (2) is hot.
d. Ream press-fitted valve guide using a valve guide reamer (com-
mercial service tool) (A).
2. If the valve seat is removed, follow the procedure below to install it.
CAUTION:
Whenever the valve seat is removed, replace it with 0.5 mm (0.020 in) oversized valve seat.
a. Ream the cylinder head (1) valve seat mounting position so that
it is the following dimension.
b. Heat cylinder head to 110 – 130
°
C by soaking it in heated oil.
c. Completely chill the service valve seat with dry ice, and press it into cylinder head.

d. Cut the valve seat to the specified dimensions using a valve
seat cutter set and valve seat grinder (commercial service tool).
CAUTION:
When using a valve seat cutter, hold the cutter handle firmly
with both hands, and press the cutter to cut the entire
periphery of the contacting face in one motion without stop-
ping. If the cutter is not pressed correctly, or if the cutter is
taken away and pressed again on the surface multiple
times, a stage valve seat may result.
e. Using an abrasive compound, grind to adjust valve seat.
f.
Check parts again. Check that the valve seat contact is normal. Refer to
.
3. Install valve oil seals.
• Using a valve oil seal drift [SST: KV10115600 (J-38958)] (A),
press-fit to the dimensions specified in the figure.
4. Install valves.
• Valves of larger diameter is installed to the intake side.
5. Install valve springs.
• Face the narrower pitch side [valve spring seat (1) press-fitted
side] toward cylinder head (B).
• Parts for intake and exhaust are different. When installing
them, check the identification colors.
6. Install valve spring retainers.
7. Install valve collets.
• Use a valve spring compressor [SST: KV10116200 (J-26336-
A)] (A), adapter [SST: KV10109220 ( — )] (B), and attachment
[SST: KV10115900 (J-26336-20)] (C), and compress the valve
spring. Then, use a magnetic screwdriver or an equivalent and
install the valve collet.

CAUTION:
• Never damage the valve lifter hole while working.
• Align the centers of the attachment [SST: KV10115900
(J-26336-20)] (A) and valve spring retainer (1).
• After installing, tap valve stem tip with a plastic hammer to ensure a proper fit.
8. Install valve lifter.
• Install them in their original positions.
9. Install spark plugs.
• Use a spark plug wrench (commercial service tool).
Inspection
INFOID:0000000012197440
INSPECTION AFTER REMOVAL
Cylinder Head Bolt Outer Diameter
• Measure the outer diameter at two locations (d1 and d2) shown in
the figure.
CAUTION:
When there is another narrowed point within the thread area,
use this point as d2.
• Calculate the difference between d1 and d2.
• Replace cylinder head bolt if limit is exceeded.
Cylinder Head Distortion
NOTE:
Check the distortion of the cylinder block top surface at the same time as this inspection. Refer to
1. Using a scraper, remove oil, scale, gasket, sealant, and carbon deposits from surface of cylinder head.
CAUTION:
Never allow gasket fragments to enter oil or engine coolant passages.
2. Check flatness of cylinder head lower surface using a straight-
edge (A) and a feeler gauge (B). Measure distortion, at several
points each in six directions.
• Replace cylinder head if the limit is exceeded.

• Using a micrometer, measure dimensions at the points shown in
the figure.
• If it exceeds the standard, replace valve.
Valve Guide Clearance
Calculate the clearance by measuring valve stem outer diameter
and guide hole diameter using a micrometer (A) and a bore gauge.
• Replace the valve guide bolt if it exceeds the limit. Refer to
275, "Disassembly and Assembly"
.
Valve Seat Contact
• This inspection must be done after ensuring that the dimensions of the valve guide and the valve are within
the standard.
• Apply DICATOL PL
−
1 to valve seat and valve face contact surfaces and check valve seating condition.
• Make sure that all connection surfaces are completely connected
around.
• Reseat the valve and check again for incorrect seating condition.
Replace valve seat if seating condition cannot be corrected by
reseating.
Valve Spring Squareness
Set the valve spring against a square (A). Rotate the spring and
record the maximum clearance (d) between spring upper end and
the square.
CAUTION:
Never remove valve spring seat (assembly parts).
• Replace valve spring if the limit is exceeded.
