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.

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.

Removing the timing belt
1. Turn the crankshaft in a clockwise direction, and match up all
the timing marks until the No.1 cylinder is in the compressor top
dead centre position.
Caution
Turn the crankshaft in the normal way.
2. Remove the rubber plug from the rear cover of the timing belt,
and prepare the special tool for adjusting bolts (MD998738).

3. Twist the special tool for adjusting bolts (MD998738) by hand
until it touches the tensioner arm.
Caution
The special tool for adjusting bolts (MD998738) can be
slowly twisted at a rate of about 30° per second but if it is
suddenly twisted the auto-tensioner rod cannot be easily
withdrawn, and this may lead to problems with twisting and
the possibility that the special tool for adjusting bolts
(MD998738) may become bent.
4. Twist the special tool for adjusting bolts (MD998738) a little, and
align the auto-tensioner rod with setting hole A, and the
tensioner cylinder with setting hole B.
5. Insert a wire or a pin into the aligned holes.
6. Remove the special tool for adjusting bolts (MD998738), and
then loosen the bolt for fitting the timing belt tensioner, and
remove the timing belt.
Caution
If a timing belt is being re-used, check and make a note of
the direction of the arrows indicating the rotational
direction (clockwise direction) on the back of the belt.

Removing the power steering oil pump ASSY
Remove the power steering oil pump ASSY from its bracket, with
the hose intact.
Note
Secure the removed power steering oil pump ASSY with string, and
put it somewhere where it will not hinder the removal or fitting of the
timing belt.

Removing the crankshaft sprocket
1. Hold the crankshaft sprocket in place using the special spanner
(MB991367) and the special pin (MB991385).

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

F 
Fitting the timing belt
1. Check that all the timing marks for the camshaft sprocket, the
crankshaft sprocket and the oil pump sprocket are aligned.
2. After the timing marks for the oil pump sprocket have been
aligned, remove the plug from the cylinder block and insert a
posidrive (+) with a diameter of 8 mm into the plug hole. Check
that more than 60 mm of the shaft of the screwdriver can be
inserted. If the screwdriver strikes the balancer shaft and can
only be inserted to a depth of 20 ~ 25 mm, turn the sprocket one
complete turn, realign the timing marks, and check that more
than 60 mm of the screwdriver can be inserted. Do not remove
the screwdriver until the timing belt has been fitted.
3. Install the timing belt in accordance with the following guidelines
so that the side that is under tension does not get slack.
(1) Fit the timing belt around the crankshaft sprocket first, then
the oil pump sprocket and then fit it around the idler pulley.
(2) Fit the timing belt around the camshaft sprocket (exhaust
side) and hold it in place with a paper clip at the position
shown in the diagram.

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.
