Caution
1. If Brembo brake callipers are being used take care that they are not scratched by other components or tools
because there is a chance that the paint might peel off. In addition, if any brake fluid gets on the callipers, it
should be wiped off immediately.
2. Parts marked with * should be removed and then fitted for each cylinder in turn.
Jobs to be completed before removal and after fitting
• Removal and refitting of the undercover (Ref Section 51: Front bumper)
• Checking the tension of the drive belt (only after fitting)

Fitting the O-ring/oil feeder control valve
Caution
1. Do not re-use O-rings.
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.

Removal guidelines
 
A


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withdrawn, and this may lead to problems with twisting and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.
 
B


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.
 
C


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

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.

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.
