•
Do not rotate engine counterclockwise.
(2)
Check that the TDC marks of the intake CVVT sprocket and exhaust CVVT sprocket are in straight line on the cylinder head surface as shown in the illustration.

  
•
If not, turn the crankshaft one revolution (360°). (Do not rotate engine counterclockwise.)
3.
Remove the timing chain cover.
(Refer to Timing System - "Timing Chain Cover")
Inspection
Sprockets, Hydraulic Tensioner, Chain Guide, Tensioner Arm
1.
Check the CVVT sprocket, crankshaft sprocket teeth for abnormal wear, cracks or damage. Replace if necessary.
2.
Check a contact surface of the chain tensioner arm and guide for abnormal wear, cracks or damage. Replace if necessary.
3.
Check the hydraulic tensioner for its piston stroke and ratchet operation. Replace if necessary.
Installation
1.
Dowel pin of crankshaft setted about 3° with vertical center line.

2.
Align the timing marks of the camshaft sprocket with the upper sureface of the cylinder head to make No.1 cylinder be positioned at TDC.

3.
Install the new O-rings (A).
4.
Install the timing chain guide (A) and the timing chain (B).
Tightening torque :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

  
•
When installing a timing chain, align the timing marks on the sprockets with the timing marks (color links) of the chain.
•
Order : Crankshaft sprocket → Timing chain guide → Intake CVVT sprocket → Exhaust CVVT sprocket
5.
Install the chain tensioner arm (A).
Tightening torque :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

6.
Install the hydraulic tensioner (A) and remove the pin (B).
Tightening torque :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

  
•
Recheck the top dead center (TDC) marks on the crankshaft and CVVT sprockets.
7.
