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.

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

with a paper clip at the position shown in the diagram.
(4) Fit the timing belt around the tensioner pulley.
(5) Remove the two paper clips.
Caution
After the timing belt has been installed, apply some force in
an anti-clockwise direction to the camshaft sprocket and
check once more that all the timing marks are in the correct
position when the side of the belt under tension is taught.
4. Using the special wrench for the tensioner pulley socket
(MD998767), tense the timing belt by turning the tensioner
pulley in the direction shown in the diagram, and temporarily
tighten the mounting bolt for the tensioner pulley.
5. Check that all the timing marks are aligned.
6. Remove the screwdriver, and replace the plug.
7. Adjust the tension of the timing belt.



G 
Adjusting the tension of the timing belt
1. Remove the rubber plug from the rear cover of the timing belt
and put the special adjusting bolt (MD998738) in position.
Slowly twist the adjusting bolt a little at a time, so that the wire
or pin inserted when fitting the auto-tensioner, only moves a
little.
Caution
There is a possibility that the wire or pin inserted in the
auto-tensioner may break if the adjusting bolt is twisted
with a spanner or a similar tool, so it must be twisted by
hand.
2. Turn the crankshaft a quarter turn in an anti-clockwise direction.
3. Turn the crankshaft in a clockwise direction, realign all the timing
marks and set the No.1 cylinder in the top dead centre position.
4. Loosen the mounting bolt for the tensioner pulley which had
been temporarily tightened.paper clips

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.

•The exhaust cam position sensor detects the compression top dead centre for each cylinder, and by simultaneous
observation of these and other controlling signals, it is possible to distinguish between the cylinders.
•The crank angle sensor detects the crank angle for each cylinder. There is an output of 4 evenly spaced crank angle sensor
HIGH signals for every 2 revolutions of the engine. Therefore, by measuring the cycle time (seconds), engine revolution
speed can calculated according to the following formula:
Engine revolution speed = 2/4T (seconds) x 60 = 30/T (seconds)

•Check that the cycle time gets shorter as the engine revolution speed increases.
