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

5.0 mm).

CAUTION:

Use protective gloves so as to prevent burns because the

cylinder head is hot.

c. Using a valve guide drift (commercial service tool: for inner

diameter

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.

CAUTION:

• Never touch chilled valve seat with bare hands.

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

EM-279, "Inspection"

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

EM-294,

"Inspection"

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

EM-

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.
