ENGINE OVERHAUL -Timing Belt11B-19
Caution
(1) Measure when the belt’s surface temperature is
close to room temperature.
(2) Make sure that water or oil, etc., do not get on
the mike.
(3) If strong winds contact the mike or if noise is
generated in the area while measuring, a value
that differs from the actual value may be indicated.
(4) If the measurement is carried out with the mike
contacted against the belt, a value that differs
from the actual value may be indicated.
(5) Do not measure while the engine is running.
11. Disconnect MUT-II.
12. When measuring with the deflection amount, press the
centre of the tensed side of timing belt B with your index
finger in the arrow direction, and confirm that the deflection
is between 5 and 7 mm.

"JAOIL PUMP SPROCKET INSTALLATION
1. Stop the rotation of the counter balance shaft in the same
manner as for removal.
2. Install the oil pump sprocket.
3. Apply the minimum required amount of engine oil on the
flange nut seat surface.
4. Tighten the flange nut at the specified torque 54±5
N•m.
"KAAUTO TENSIONER INSTALLATION
1. If the auto tensioner rod is in the extended state, set
it with the following steps.
(1) Set the rod of the auto tensioner into a vice so that
it is straight and not inclined.
(2) Press in the rod gradually with the vice, and align
the rod’s set hole A with the cylinder’s set hole B.
(3) Insert a wire (diameter 1.4 mm) into the set holes.
(4) Remove the auto tensioner from the vice.
2. Install the auto tensioner.
Do not remove the wire until the timing belt has been
installed.
"LATENSIONER PULLEY INSTALLATION
Set the tensioner pulley as shown in the illustration.
"MATIMING BELT INSTALLATION
1. Set the timing mark on the exhaust side camshaft sprocket
so that it is deviated by one tooth in the counterclockwise
direction from the timing mark on the rocker cover.
NOTE
Even if the sprocket and rocker cover timing marks are
aligned, the exhaust camshaft will return in the
counterclockwise direction by the force of the valve spring
and will stabilize at a position deviated by one tooth.

14. Using the special tool, rotate the tensioner pulley in the
counterclockwise direction to tense the timing belt, and
then fix by temporarily tightening the tensioner fixing bolt.
NOTE
Remove the deflection of the timing belt between the
intake side and exhaust side camshafts.
15. Rotate the crankshaft in the clockwise direction, and set
the timing mark at the No. 1 cylinder compression top
dead centre.
16. Set the special tool, and screw it in until the wire inserted
when the auto tensioner was installed slightly moves.
17. Loosen the tensioner pulley fixing bolt.
Caution
The timing belt will loosen at this time due to the
rotation of the intake and exhaust camshafts, so make
sure that the timing belt does not deviate.
18. Rotate the special tool and torque wrench in the
counterclockwise direction to remove the timing belt
deflection.
19. From that state, return to the position where the torque
wrench scale reads 3.5 N•m, and then tighten the fixing
bolt.
20. Remove the special tool installed in step 16.
21. Rotate the crankshaft two rotations in the clockwise
direction, and let stand for approx. 15 minutes.
22. Confirm whether the wire inserted when the auto tensioner
was installed can be pulled out easily. If it can be removed
easily, the belt tension is appropriate, so remove the wire.
If the auto tensioner rod’s protrusion amount is at the
standard value, the tension is appropriate.
Standard value: 3.8 - 4.5 mm
23. If the wire cannot be pulled out easily, repeat steps 16
to 21, and tense the belt to the appropriate tension.
Caution
When the crankshaft bolt has been rotated in the
counterclockwise direction, always check the crank-
shaft bolt’s tightening torque. If loosen, re-tighten.

"AAINJECTOR INSTALLATION
1. Apply a small amount of new engine oil on the O-ring.
2. While rotating the injector to the left and right, insert the
O-ring into the delivery pipe while taking care not to
damage it.
Caution
Make sure that the engine oil does not enter the
delivery pipe.
3. Confirm that the injector rotates smoothly. If it does not
rotate smoothly, the O-ring may be biting in. Remove
the injector, check the O-ring for damage, and then insert
it into the delivery pipe. Check the rotation again.
"BAFUEL PRESSURE REGULATOR INSTALLATION
1. Apply a small amount of new engine oil on the O-ring.
2. While rotating the fuel pressure regulator to the left and
right, insert the O-ring into the delivery pipe while taking
care not to damage it.
Caution
Make sure that the engine oil does not enter the
delivery pipe.
3. Confirm that the fuel pressure regulator rotates smoothly.
If it does not rotate smoothly, the O-ring may be biting
in. Remove the fuel pressure regulator, check the O-ring
for damage, and then insert it into the delivery pipe. Check
the rotation again.

5. VALVE SEAT
Assemble the valve, and measure the amount that the
valve protrudes from the valve shaft end between the
spring seat surfaces when the valve is pressed against
the valve seat. Replace the valve seat if the protrusion
amount exceeds the limit value.
Standard value:
Intake 49.20 mm
Exhaust 48.40 mm
Limit value:
Intake 49.70 mm
Exhaust 48.90 mm
Valve Seat Correction
1. Before correcting the valve seat, inspect the clearance
between the valve guide and valve, and replace the valve
guide if necessary.
2. Correct so that the seat width and seat angle are at the
specified shape.
3. After correcting, apply wrapping compound, and fit the
valve and valve seat together.
Valve Seat Replacement
1. Grind off the valve seat to be replaced from the inside
to reduce the thickness and then remove the valve seat.
2. Machine the valve seat hole on the cylinder head to match
the diameter of the oversized valve seat into which it
is to be pressed in.
Intake valve seat hole diameter:
0.3 O.S. 35.30 - 35.33 mm
0.6 O.S. 35.60 - 35.63 mm
Exhaust valve seat hole diameter:
0.3 O.S. 33.30 - 33.33 mm
0.6 O.S. 33.60 - 33.63 mm
3. When pressing in the valve seat, cool the valve seat
with liquid nitrogen, and make sure that the inner diameter
of the cylinder head is not galled.
4. Refer to the “Valve Seat Correction” procedures, and
machine the valve seat.Valve shaft end
