WARNING:

Put a “CAUTION INFLAMMABLE” sign in the workshop.

Be sure to work in a well ventilated area and furnish workshop with a CO2 fire extinguisher.

Do not smoke while servicing fuel system. Keep open flames and sparks away from the work area.

To avoid the danger of being scalded, do not drain engine coolant when the engine is hot.
1. Remove engine cover with power tool. Refer to EM-19, "
INTAKE MANIFOLD COLLECTOR" .
2. Release fuel pressure. Refer to EC-99, "
FUEL PRESSURE RELEASE" .
3. Drain engine coolant, or when water hoses are disconnected, attach plug to prevent engine coolant leak- age. Refer to CO-11, "
Changing Engine Coolant" and EM-19, "INTAKE MANIFOLD COLLECTOR" .
CAUTION:
Perform this step when the engine is cold.

Lubricate O-ring with new engine oil.

Do not clean O-ring with solvent.

Make sure that O-ring and its mating part are free of foreign material.

When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not
to twist or stretch O-ring. If O-ring was stretched while it was being attached, do not insert it
quickly into fuel tube.

Insert new O-ring straight into fuel tube. Do not decenter or twist it.

Insert fuel damper and fuel sub-tube straight into fuel tube.

Tighten mounting bolts evenly in turn.

After tightening mounting bolts, make sure that there is no gap between flange and fuel tube.
2. Install new O-rings to fuel injector, paying attention to the following.
CAUTION:

Upper and lower O-ring are different. Be careful not to confuse them.

Handle O-ring with bare hands. Do not wear gloves.

Lubricate O-ring with new engine oil.

Do not clean O-ring with solvent.

Make sure that O-ring and its mating part are free of foreign material.

When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not to
twist or stretch O-ring. If O-ring was stretched while it was being attached, do not insert it
quickly into fuel tube.

Insert O-ring straight into fuel injector. Do not decenter or twist it.
3. Install fuel injector to fuel tube as follows:
a. Insert clip into clip mounting groove on fuel injector.

Insert clip so that protrusion “A” of fuel injector matches cutout
“A” of clip.
CAUTION:

Do not reuse clip. Replace it with a new one.

Be careful to keep clip from interfering with O-ring. If
interference occurs, replace O-ring.
b. Insert fuel injector into fuel tube with clip attached.

Insert it while matching it to the axial center.

Insert fuel injector so that protrusion “B” of fuel tube matches
cutout “B” of clip.

Make sure that fuel tube flange is securely fixed in flange fix-
ing groove on clip.
c. Make sure that installation is complete by checking that fuel injector does not rotate or come off.

Make sure that protrusions of fuel injectors are aligned with
cutouts of clips after installation.
4. Install spacers on intake manifold.
5. Install fuel tube and fuel injector assembly to intake manifold. CAUTION:
Be careful not to let tip of injector nozzle come in contact with other parts. Fuel tube side : Blue

9. Remove spark plug tube, as necessary.

Using a pliers, pull spark plug tube out of cylinder head.
CAUTION:

Take care not to damage cylinder head.

Once removed, spark plug tube will be deformed and cannot be reused. Do not remove it unless
absolutely necessary.
ASSEMBLY
1. When valve guide is removed, install it. Refer to EM-108, "VALVE GUIDE REPLACEMENT" .
2. When valve seat is removed, install it. Refer to EM-109, "

a. Apply new engine oil on valve oil seal joint and seal lip.
b. Install with the valve oil seal drift [SST] to match dimension in the figure.
4. Install valve spring seat.
5. Install valve.

Larger diameter valves are for intake side.
NOTE:
Larger diameter valves are for intake side.
6. Install valve spring (uneven pitch type).

Install narrow pitch end (paint mark) to cylinder head side
(valve spring seat side).

Intake side and exhaust side valve springs are different.
Install them referring to the following paint mark collar.
7. Install valve spring retainer.

4. Heat cylinder head to 110 to 130°C (230 to 266 °F) by soaking in
heated oil.
5. Using the valve guide drift (commercial service tool), press valve guide from camshaft side to the dimensions as in the figure.
WARNING:
Cylinder head contains heat. When working, wear protec-
tive equipment to avoid getting burned.
6. Using the valve guide reamer (commercial service tool), apply reamer finish to valve guide.
VALVE SEAT CONTACT

After confirming that the dimensions of valve guides and valves
are within the 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-109, "
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-156, "

Main Bearing Grade Table (All Journals)
Undersize Bearing Usage Guide

When the specified main bearing oil clearance is not obtained with standard size main bearings, use
underside (US) bearing.

When using undersize (US) bearing, measure the main bearing inner diameter with bearing installed, and
grind main journal so that the main bearing oil clearance satisfies the standard.
CAUTION:
In grinding crankshaft main journal to use undersize bear-
ings, keep the fillet R [1.5 - 1.7 mm (0.059 - 0.067 in)].

VALVE LIFTER OUTER DIAMETER

Measure the outer diameter of valve lifter with micrometer.
VALVE LIFTER HOLE DIAMETER

Measure the inner diameter of valve lifter hole of cylinder head
with inside micrometer.
VALVE LIFTER CLEARANCE

(Valve lifter clearance) = (Valve lifter hole diameter) – (Valve lifter outer diameter)

If the calculated value is out of the standard, referring to each standard of valve lifter outer diameter and
valve lifter hole diameter, replace either or both valve lifter and cylinder head.
INSTALLATION
1. Install valve lifters and adjusting shims if removed.

Install it in the original position.
2. Install camshafts.

Follow your identification marks made during removal, or fol-

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-277, "
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 valve guide center.
This will enable valve to fit correctly.
3. Heat cylinder head to 110 to 130 °C (230 to 266 °F) by soaking in
heated oil.
4. Provide valve seats cooled well with dry ice. Force fit valve seat into cylinder head. CAUTION:

Avoid directly touching cold valve seats.

Cylinder head contains heat. When working, wear protective equipment to avoid getting burned.
5. Using valve seat cutter set (commercial service tool) or valve seat grinder, finish seat to the specified dimensions. Refer to
EM-277, "
Va l v e S e a t" .
CAUTION:
When using valve seat cutter, firmly grip cutter handle with
both hands. Then, press on the contacting surface all
around the circumference to cut in a single drive. Improper
pressure on with cutter or cutting many different times may
result in stage valve seat.
