(3) Tighten the bolts by the following procedure.
StepOperation
1Tighten to 78 Nm {8.0 kgf
m} in the order shown in the
illustration.
2Fully loosen in the reverse order of that shown in the
illustration.
3Tighten to 20 Nm {2.0 kgf
m} in the order shown in the
illustration.
4Mark the head of the cylinder head bolt and cylinder head
by paint, then tighten 90
of a turn in the order shown in
the illustration.
5Tighten 90
of a turn in the order shown in the illustration.
Check that the painted mark of the head bolt is lined up
with that of the cylinder head.
Caution
(1) Always make a tightening angle just 90
. If it is less
than 90
, the head bolt will be loosened.
(2) If it is more than 90
, remove the head bolt and repeat
the procedure from step 1.
COIL RETURN PIPE GASKET INSTALLATION
Install the gasket with the printed portion toward the oil pan.
DHIGH-PRESSURE FUEL HOSE INSTALLATION
(1) Apply a small amount of new engine oil to the O-ring,
then fit the O-ring in the delivery pipe.
Caution
Do not let any engine oil get into the delivery pipe.
(2) Check that the high pressure hose turns smoothly.
If the hose does not turn smoothly, the O-ring is probably
being clamped. Disconnect the high-pressure fuel hose
and check the O-ring for damage. After this, re-install
the hose to the delivery pipe and check that the hose
turns smoothly.
(3) Tighten the mounting bolts to the specification.

REMOVAL SERVICE POINTS

ATIMING BELT REMOVAL
(1) If the timing belt is to be reused, chalk an arrow mark
on the back surface of the belt so that the belt can be
reinstalled in the same direction.
(2) Place the exhaust camshaft sprocket in a position where
the timing mark for No. 1 cylinder is positioned about
one tooth before the top dead center of the compression
stroke.
Caution
The camshaft sprocket on the exhaust side can turn
very easily because of the valve spring tension. Use
care not to allow your fingers to get caught by the
sprocket.
(3) Loosen the lock nut of the tensioner pulley, then remove
the timing belt.

BOIL PUMP SPROCKET REMOVAL
(1) Remove the plug on the left side of cylinder block.
(2) Insert a screwdriver (shank diameter 8 mm) to block the
counterbalance shaft.
(3) Loosen the flange bolt.
(4) Remove the oil pump sprocket.

SPACER INSTALLATION
(1) Apply very thin coat of oil to the outer periphery of the
spacer (oil seal contacting surface).
(2) Install the spacer with the chamfered end toward the
oil seal. Mounting in the reverse direction can damage
the oil seal lip.

TIMING BELT “B” INSTALLATION
(1) Align timing marks on the crankshaft sprocket “B” and
counterbalance shaft sprocket with the marks on the front
case respectively.
(2) Install the timing belt “B” on the crankshaft sprocket “B”
and counterbalance shaft sprocket. There should be no
slack on the tension side.

(3) Make sure that the relationship between the tensioner
pulley center and the bolt center is as shown in the
illustration.
(4) Move the tensioner “B” in the direction of arrow while
lifting with a finger to give a sufficient tension to the tension
side of timing belt. In this condition, tighten bolt to secure
tensioner “B” . When the bolt is tightened, use care to
prevent shaft from turning together. If shaft is turned
together, belt will be overtensioned.

OIL PUMP SPROCKET INSTALLATION
(1) Block the counterbalance shaft in the same way as at the disassembly to prevent it from turning.
(2) Install the oil pump sprocket.
(3) Apply a proper amount of engine oil to the bearing surfaces
of the flange nuts.
(4) Tighten the flange nuts to the specified torque.
 J
AUTO TENSIONER INSTALLATION
(1) If the auto tensioner rod is in its fully extended position, reset it as follows.
a. Clamp the auto-tensioner in the vise with soft jaws.
b. Push in the rod little by little with the vise until the
set hole A in the rod is aligned with the hole B in
the cylinder.

(4) Align the timing mark on the oil pump sprocket with its
mating mark.
(5) Remove the plug on the left side of the cylinder block
and insert a Phillips screwdriver (shank diameter 8 mm)
through the hole.
If it can be inserted as deep as 60 mm or more, the
timing marks are correctly aligned. If the inserted depth
is only 20 – 25 mm, turn the oil pump sprocket one turn
and realign timing marks. Then check to ensure that the
screwdriver can be inserted 60 mm or more.
(6) Remove the Phillips screwdriver. Place the oil pump sprocket in a position where its timing mark is one tooth
offset from the mated timing mark in the counterclockwise
direction.
(7) Fit the timing belt over the exhaust side camshaft sprocket, and secure it at the illustrated position using a paper
clip.
(8) Turn the intake side camshaft sprocket as shown to a position where its timing mark is one tooth offset from
the mated timing mark in the counterclockwise direction.
Then, fit the timing belt over the sprocket and secure
it with a paper clip.
NOTE
The intake camshaft will be turned a little clockwise by
the valve spring tension and stabilized in position even
if the belt is clipped at one tooth offset position.
(9) Check to ensure that the timing marks on the intake camshaft sprocket side are in alignment when the exhaust
camshaft sprocket is turned clockwise to align the timing
marks.
NOTE
The timing belt span between the intake and exhaust
sprockets will have 17 cogs.

(10)Fit the timing belt over the idler pulley, oil pump sprocket
and crankshaft sprocket in this order.
NOTE
Be careful that the belt does not become slack.
(11) Fit the timing belt over the tensioner pulley. NOTE
When fitting the timing belt over the tensioner pulley,
turn the intake side camshaft sprocket a little
counterclockwise, as this will facilitate the work.
(12)Turn the crankshaft pulley a little in the illustrated direction to pull up the timing belt at the idler pulley side.
(13)Check to ensure that the timing marks on the crankshaft sprocket, oil pump sprocket and exhaust camshaft
sprocket are all offset one tooth from the corresponding
timing marks in the counterclockwise direction.
(14)Using the special tool, turn the tensioner pulley in the illustrated direction to strain the timing belt. Then, secure
the tensioner temporarily by tightening the retaining bolt
lightly.
NOTE
There must be no slack in the timing belt between the
intake and exhaust camshafts.
(15)Turn the crankshaft to align the timing mark with the mark for No. 1 cylinder top dead center in the compression
stroke.
(16)Set the special tool as shown and screw it in up to the position where the wire inserted in the auto-tensioner
when installing it can be moved lightly.
