Installation
1. Install the jack to the upper oil pan.
2. The key (A) of crankshaft should be aligned with the timing mark (B) of timing chain cover. As a result of this, the piston of No.1 cylinder is placed at the top dead center on compression stroke.
3. Install the tensioner adapter assembly (A).
4. Install the crankshaft sprocket (A) (LH camshaft drive).
5. Install the LH timing chain guide (A).
Tightening torque
19.60 - 24.50Nm(2.0 - 2.5kgf.m, 14.17 - 18.08lb-ft)
6. Install LH timing chain.
To install the timing chain with no slack between each shaft (cam, crank), follow the procedure below.
Crankshaft sprocket -> Timing chain guide -> Exhaust camshaft sprocket(C) -> Intake camshaft sprocket(D).
The timing mark of each sprocket should be matched with timing mark (color link) of timing chain at installing timing chain.
7. Install the LH timing chain tensioner arm(B).
Tightening torque
18.62 - 21.56Nm(1.9 - 2.2kgf.m, 13.74 - 15.91lb-ft)
8. Install the LH chain tensioner (A).
Tightening torque
9.80 - 11.76Nm(1.0 - 1.2kgf.m, 7.23 - 8.68lb-ft)
9. Install the LH cam-to-cam guide (A).
