TIMING CHAIN
2. Apply a continuous bead of liquid gasket (E) (ThreeBond
1217H or equivalent) to the position shown in the figure,
while checking for overlaps. Refer to
.
NOTE:
Start the application of liquid gasket. End application when it
overlaps by 5 mm (0.20 in) or more.
3. Tighten bolts in the numerical order shown in the figure.
NOTE:
Bolt 6 in the figure shows the second tightening of bolt 1.
f.
Tighten bolts again in the numerical order shown in the figure.
CAUTION:
After tightening the mounting bolts, wipe away any liquid gasket that is squeezed out.
11. Install crankshaft pulley according to the following procedure.
a. Install the crankshaft pulley without damaging the front oil seal.
CAUTION:
Never tap crankshaft pulley periphery when press-fitting using a plastic hammer. Lightly tap
crankshaft pulley center.
b. Apply engine oil to the crankshaft pulley bolt and seat surface.
c.
Fix crankshaft pulley in place (1) using a pulley holder (commer-
cial service tool) (A).
CAUTION:
• When the pulley holder is secured, use a piece of wood or
an equivalent so that the pulley holder does not contact
any surrounding parts.
• Secure the pulley holder so as to locate it at a right angle
to the crankshaft pulley.
d. Tighten the crankshaft pulley bolt.

e. Use paint or other means to put matching marks (B) on the
crankshaft pulley (2) aligned with the matching marks (6 stamp
lines) (A) on the crankshaft pulley bolt (1).
f.
Tighten the crankshaft pulley bolt by 60
° (1 stamp line) (angle tightening).
g. Use a manual tool to rotate the crankshaft clockwise, as viewed from engine front side, and check that it
turns smoothly.
12. Install removed parts in the reverse order of removal.
CAUTION:
When replacing the timing chain, remove the 2D code label from the electric throttle control actua-
tor, and clear the valve timing variation value. Refer to
.
Inspection
INFOID:0000000012197430
INSPECTION AFTER REMOVAL
• Check for cracks (A) or excessive wear (B) of the timing chain and
oil pump drive chain.
• Replace the timing chain and the oil pump drive chain when an
abnormal condition is found.
INSPECTION AFTER INSTALLATION
Engine Oil Leakage Inspection
With engine warmed up, check for engine oil leakage at locations where parts are removed and reinstalled.
CAUTION:
Start the check at least 30 minutes or more after installing liquid gasket applied parts (final step). This
allows time for hardening of liquid gasket.

Removal and Installation
INFOID:0000000012197432
CAUTION:
All rotation directions indicated in the text are described as seen from engine front.
REMOVAL
1. Remove the following parts.
• Intake manifold: Refer to
EM-197, "Removal and Installation"
.
• Rocker cover: Refer to
EM-214, "Removal and Installation"
• Front cover: Refer to
EM-249, "Removal and Installation"
• Timing chain: Refer to
EM-249, "Removal and Installation"
CAUTION:
Never rotate crankshaft and camshaft separately, for preventing the valve from interfering with
piston during the procedure.
NOTE:
The removal of oil pump drive components is not necessary.
2. Remove the camshaft position sensor and exhaust valve timing position sensor from the camshaft
bracket.
CAUTION:
Never subject parts to impact.
3. Use paint or other means to put matching marks (A) on the cam-
shaft sprocket (INT) (2), camshaft sprocket (EXH) (3), and cam-
shaft bracket (1) as shown in the figure.
NOTE:
This prevents the knock pin of the camshaft from engaging with
the incorrect pin hole when installing the camshaft sprockets.
4. Remove the camshaft sprocket (INT) (1) and the camshaft sprocket (EXH) (2).
• Hold the hexagonal part of the camshaft (A) to fix the camshaft
in place, and then loosen the camshaft sprocket mounting
bolts.
CAUTION:
• After removing the timing chain, never rotate camshaft
and crankshaft individually for prevent valve from inter-
fering with piston.
• Be sure to hold the camshaft hexagonal part so that the
chain tension does not loosen the sprocket mounting
bolts.
5. Remove camshaft bracket according to the following procedure.
a. Loosen bolts in the reverse order of the numerical order shown
in the figure.
