2. Because camshaft bearing caps Nos. 2~5 are the same shape,
check the identification marks on them so that the bearing cap
number and the inlet and exhaust sides are not mistaken. Then
fit them in the direction shown in the diagram.

3. Apply sealant at the 8 places shown in the diagram of the top
view of the cylinder head.
Semi-dry sealant: Three bond 1207D
4. Fit the rear camshaft bearing cap in the direction indicated by
the front mark.

identification marks on the front camshaft bearing cap so that
the exhaust side and the inlet side are not mistaken.
6. Tighten the bearing cap mounting bolts gradually, 2~3 turns at a
time, to the specified torque.
Tightening torque: 20 ± 1 N•m

the camshaft sprocket, and fit the camshaft into the camshaft
sprocket.
3. Hold the hexagonal part of the camshaft with a wrench, and
check that the camshaft sprocket cannot be twisted.
Note
This operation is necessary because it is impossible to check by
looking whether the camshaft dowel pins are inserted into the
dowel pin holes in the camshaft sprocket.
4. Apply engine oil to the screw thread and the underside of the
camshaft sprocket mounting bolt, and in the same way as when
the camshaft sprocket was removed, hold the camshaft in place
using a wrench and tighten the bolt to the specified torque.

2. When fitting O-rings, first wind some non-adhesive tape
(seal tape etc) around the oil channel of the oil feeder
control valve, in order to prevent damage to the O-ring.
If the O-ring touches the oil it could start an oil leak.
1. Apply engine oil to the O-ring on the oil feeder control valve.
2. Fit the oil feeder control valve to the cylinder head.
3. Tighten the mounting bolts for the oil feeder control valve to the
specified torque.

3. Use the special wrench for cylinder head bolts (MB991654) to
(loosely) tighten the bolts in the following order.
(1) In the order shown in the diagram, tighten the bolts to
78 ± 2 N•m.
(2) In reverse order to that shown in the diagram, completely loosen
the bolts.
(3) In the order shown in the diagram, tighten the bolts to
20 ± 2 N•m.
(4) Make a paint mark on the top of the cylinder head bolt, and on
the cylinder head, and tighten them to 90° as shown in the
diagram.
(5) Tighten the bolts to 90° as shown in the diagram, and check that
the paint mark on the top of the cylinder head bolt and the paint
mark on the cylinder head are in line.
Caution
1) If a bolt is tightened to an angle of less than 90° it has not
been tightened sufficiently.
2) If the angle of tightening exceeds the regulation level,
remove the bolt and start again from procedure number (1).
C
Fitting the O-ring/fuel high pressure hose
1. Apply a little fresh engine oil to the O-ring.
Caution
Ensure that engine oil does not get inside the delivery pipe.
2. Without damaging the O-ring, twist the fuel high pressure hose
to fit it to the delivery pipe, making sure that it is twisted
smoothly.
3. If the hose cannot be twisted smoothly, there is a possibility that
it may be biting into the O-ring, so remove the fuel high pressure
hose, and check for any damage to the O-ring. If the O-ring is
undamaged, reinsert it into the delivery pipe and check once
more whether the hose can be turned smoothly.
4. Tighten the mounting bolts for the fuel high pressure hose to the
specified torque.
Tightening torque: 5.0 ± 1.0 N•m.

Removing timing belt B
Caution
If planning to re-use a timing belt B, ensure that it will be
refitted the same way round, by marking the back of the belt
with chalk arrows indicating the direction of movement.
Fitting guidelines
A
Fitting timing belt B and the timing belt B tensioner
1. Check that the timing marks for the crankshaft sprocket and the
balancer shaft sprocket are aligned.
2. Fit timing belt B onto the crankshaft sprocket and the balancer
shaft sprocket. Ensure that the side of the belt under tension is
not slack.
3. As a temporary step, fit the timing belt B tensioner pulley so that
its centre is to the upper left of the centre of the mounting bolt,
and so that the flange of the pulley is facing towards the front of
the engine.
4. Adjust the tension of timing belt B.
B
Adjusting the tension of timing belt B
1. Hold the timing belt B tensioner between fingertips and in the
direction of the arrows, apply tension torque (3.0 ± 0.4 N·m) to
timing belt B until the side of the belt under tension becomes
taught. In this condition, tighten the mounting bolt to the
specified torque, and fit the tensioner.
Tightening torque: 19 ± 3 N·m
Caution
When tightening the mounting bolt, ensure that the
tensioner does not turn round with it. If the tensioner turns
with the mounting bolt, it could cause the tension in the belt
to become too high.

Fitting the crankshaft sensing blade and the
crankshaft sprocket
1. Clean, and remove any grease from the crankshaft sensing
blade, the crankshaft sprocket, and the surface of the crankshaft
to which the crankshaft sprocket will be fitted.
2. Fit the crankshaft sensing blade and the crankshaft sprocket in
the direction shown in the diagram.
3. Clean the screw hole in the crankshaft.
4. Place the washer with the larger surface side in the direction as
shown in the diagram, and fit it to the crankshaft bolt.
5. Apply a small quantity of engine oil to the top and to the screw
thread parts of the crankshaft bolt.
6. In the same way as when it was removed, hold the crankshaft
sprocket using the special tool, and tighten the crankshaft bolt to
the specified torque.
Tightening torque: 167 N·m
D
Fitting the auto-tensioner
1. If the auto-tensioner rod remains in an extended state, install it
using the following procedure.
(1) Using a press or a vice, slowly compress the auto-
tensioner rod and align the rod with setting hole A and the
tensioner cylinder with setting hole B.
Caution
If the speed of compression is too fast, there is a
chance that the rod may break, so carry out this
operation slowly.
(2) Insert a wire or pin into the aligned holes.
Note
If a brand new or a replacement auto-tensioner is being
used, use a pin to set the auto-tensioner in place.
2. Fit the auto-tensioner into the engine and tighten the mounting
bolt to the specified torque. Do not remove the wire or pin until
the tension of the timing belt has been adjusted.
Tightening torque: 23 ± 3 N·m

5. Using the special wrench for the tensioner pulley socket
(MD998767) or a torque wrench, apply tension torque (3.5 N·m)
to the timing belt in the direction shown in the diagram, and
tighten the mounting bolt for the tensioner pulley to the specified
torque.
Tightening torque: 48 ± 5 N·m
Caution
When tightening the installed bolt, take care that the
tensioner pulley does not turn around with it. If the pulley
does turn around with the bolt, the tension of the belt will
become too strong.
6. Remove the wire or pin which had been inserted when the auto-
tensioner was fitted.
7. Remove by hand the special adjusting bolt (MD998738) which
had been fitted in step 1.
8. Turn the crankshaft two complete turns in a clockwise direction,
and leave it for about 15 minutes.
9. Reinsert the wire or pin which had been removed in step 6, and
check that it can be easily pulled out again.
If the wire or pin can be easily pulled out the tension of the
timing belt is just right, so the wire or pin should be removed
completely. At this point check that the auto-tensioner rod is not
projecting more than the amount specified.
Specified projection (A): 3.8 ~ 4.5 mm
10. If the wire or pin cannot be easily pulled out, repeat steps 1 to 8
until the tension of the timing belt is just right.
11.Recheck that the timing marks on all of the sprockets are in line.
Caution
If the crankshaft bolt is turned in an anti-clockwise
direction, the tightening torque of the crankshaft bolt must
be checked, and if it is loose, it must be retightened.
