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.

(3) Use a wrench to align the timing marks on the rocker cover and
the camshaft sprocket, and whilst doing so, fit the timing belt
around the camshaft sprocket (inlet side) and hold it in place
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

ENGINE – TIMING BELT, TIMING BELT B, ENGINE ASSY11-28
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.
