Installation

INSTALLATION

NOTE:
^ Be careful that the foreign matter is not into or onto assembled component during installation.
^ Apply engine oil to the all timing chain components.

1) Preparation for chain tensioner installation.
(1) Insert the screw, spring pin and tension rod into tensioner body.
(2) Rotate the rubber mat counterclockwise while pressing the chain tensioner from upper side by hand as shown in the figure.

NOTE: Degrease the contact surface between tension rod top portion and rubber mat, to prevent slipping.





(3) Insert the stopper pin into the chain tensioner body hole.
2) Set the oil pump shaft knock pin at the six o'clock position as shown in the figure.





3) Using the ST, align the "Top mark" on crank sprocket to nine o'clock position as shown in the figure





4) Align the intake cam sprocket to 12 o'clock position as shown in the figure.





5) Align the exhaust cam sprocket to 12 o'clock position as shown in the figure.





6) Using the ST, align the "Top mark" on crank sprocket to 12 o'clock position as shown in the figure

NOTE:
^ Piston #1 is at top dead center (TDC) position.
^ Do not rotate the crankshaft and cam sprocket before completing timing chain installation.
^ Crank sprocket key is located at three o'clock position.





7) Install the chain guide (Main).
Tightening torque: 16 N-m (1. 6 kgf-m, 11. 8 ft-lb)





8) Install the idler sprocket and timing chain (Main).
(1) Align the timing chain mark (gold) to the idler sprocket timing mark position.
