TIMING CHAIN".
1. Release fuel pressure. Refer toEC-34, "
FUEL PRESSURE RELEASE",EC-399, "FUEL PRESSURE
RELEASE".
2. Remove parts listed below.
lIgnition Coil; Refer toEM-27, "Removal and Installation".
lRocker cover; Refer toEM-31, "Removal and Installation".
3. Remove power steering reservoir tank.

and remove camshaft brackets and camshafts.
lRemove No.1 camshaft bracket by slightly tapping it with a
soft tool such as a plastic hammer.
9. Remove valve lifter.
lCheck mounting positions, and store them without mixing
them up.
INSTALLATION
1. Install valve lifter.
lInstall them in the same positions they were in prior to removal.
2. Install camshaft.
lDistinction between intake and exhaust camshafts is performed with a difference of shapes of rear end.
Intake : Signal plate shape for camshaft position (PHASE) sensor.
Exhaust : Cone end shape.
lInstall camshafts so that knock pins on the front side are posi-
tioned as shown in the figure.

the marks on timing chain with the ones on each sprocket.
CAUTION:
lAligned mating marks could slip. Therefore, after matching
them, hold the timing chain in place by hand.
lBefore and after installing chain tensioner, check again to
make sure that mating marks have not slipped.
6. Install chain tensioner.
CAUTION:
lAfter installation, pull the stopper pin off completely, and make sure that tensioner is released.
