B 
Fitting the valve spring
Fit the valve spring so that the end of the valve spring which has
the smaller radius is on the rocker arm side.



C 
Fitting the valve spring retainer lock
In the same way as when the valve spring retainer lock was
removed, compress the valve spring using the special tool for
compressing valve springs (MD998772), and fit the valve spring
retainer lock.



D 
Fitting the rush adjuster
Caution
If a rush adjuster is being reused, it must be washed and
inspected before fitting.

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.
5. In just the same way as for bearing caps Nos. 2~5, check the
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.

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.

diagram (No.1 cylinder compression top dead centre).
Note
Under pressure from the exhaust valve spring, it will turn slightly
in an anti-clockwise direction.
2. As shown in the diagram, fit the pane (small) of the camshaft
position sensing cylinder (exhaust side) so that it is in a position
approximately 45° to the exhaust camshaft dowel pin.
3. Tighten the mounting bolts for the camshaft position sensing
cylinder to the specified torque.

Removal guidelines



A 
Removing the cylinder head bolts
Use the special wrench for cylinder head bolts (MB991654) to turn
the bolts 2~3 times in order to loosen them, before removing them
in the numerical order as shown in the diagram.
Fitting guidelines



A 
Fitting the cylinder head gasket
1. Remove the gaskets which have been stuck onto the surface of
the gasket.
Caution
Do not allow any foreign matter to get into the channels for
coolant or oil, or into the cylinder.
2. Fit the cylinder head gasket to the cylinder head, so that the
holes in the cylinder head gasket match up with the holes in the
cylinder head.



B 
Fitting the cylinder head bolts
1. Check that the length of the body of cylinder head bolts is less
than the maximum permitted. If the length is in excess of the
maximum permitted, replace the bolt with a brand new one.
Maximum length (A): 99.4mm
2. Apply a small amount of engine oil to the screw thread of the
bolt, and to the washer.

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.

D 
Fitting the oil return pipe gasket
Replace the gasket with a new one, and fit it to the protruded part
shown in the diagram.
Note:
For the oil return pipe gasket on the turbocharger side, there is no
direction for slotting it in.



E 
Fitting the eyebolts
Caution
When tightening the eyebolts, hold the oil pipe joint in place
with a spanner so that it does not turn round as the eyebolts
are tightened.

2. <Measuring the amount of give>
(1) As shown in the diagram, apply a force of about 100N to the
middle of the belt between the sprockets (indicated by the
arrow), and check that the amount of give is as specified.
Specified values:
<when adjusted> 5~7mm
<when replaced> 5~7mm
(2) If the specified values are not met, readjust the tension of the
belt.
3. <When using MUT-II/III>
(1) Connect the special belt tension meter set (MB991668) to the
MUT-II/III.
(2) Connect the special battery harness (MB991704) to the MUT-
II/III, and also connect it to the batteries.
(3) Give the crankshaft two turns in a clockwise direction, and check
that the No.1 cylinder is in the top dead centre position, and that
the timing marks on each sprocket are aligned.
(4) Select the “belt tension measurement” option from the display
on the MUT-II/III.
(5) As shown in the diagram hold the special belt tension meter set
(MB991668) in the middle of the belt between the sprockets
(indicated by the arrow), 10~20mm away from the outer side of
the belt and vertically to the belt (not leaning more than ±15°
away from vertical).
(6) As shown in the diagram, lightly pull the middle of the belt
between the sprockets (indicated by the arrow) using fingertips
and check that the vibration frequency of the belt is within the
limits specified.
Specified values: 76 ~ 92 Hz
Caution
(1) The meter may give an incorrect reading if the
microphone is affected by a strong wind, or if there are
loud noises nearby, while testing is taking place.
(2) The meter may give an incorrect reading if testing is
performed while the microphone is touching the belt.
(7) If the specified values are not met, readjust the tension of the
belt.

C 
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
