Removal and fitting
Caution
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.
Jobs to be completed before removal and after fitting
•Removal and refitting of the valence. (Ref Section 51: Front bumper)
•Removal and refitting of the LH side cover.
•Checking and adjustment of the tension of the drive belt. <Only after fitting>
•Removal and refitting of the crankshaft pulley.
•Removal and refitting of the cross member bar.
•Removal and refitting of the front exhaust pipe.

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.
