Turn the crankshaft pulley clockwise, and align its groove with the timing mark of the timing chain cover.
Turn the crankshaft pulley clockwise, and align its groove with the timing mark of the timing chain cover.
Remove the timing chain cover.
(Refer to Timing System - "Timing Chain Cover")
Align the timing marks of the camshaft sprocket with the upper surface of the cylinder head to make No.1 cylinder be positioned at TDC.
Check the dowel pin of the crankshaft for facing upside of the engine at this monent.
Put paint marks on the timing chain links(3 places) that meet with the timing marks of the camshaft sprockets(In, Ex : 2) and the crankshaft sprocket.
Remove the hydraulic tensioner (A).
Before removing the tensioner, fix the piston of the tensioner with a pin through the hole (B) at TDC.
Remove the Timing Chain Tensioner Arm (A) and Guide (B).
Remove the timing chain (A).
Check the camshaft sprocket, crankshaft sprocket teeth for abnormal wear, cracks or damage. Replace if necessary.
Check a contact surface of the chain tensioner arm and guide for abnormal wear, cracks or damage. Replace if necessary.
Check the hydraulic tensioner for its piston stroke and ratchet operation. Replace if necessary.
Dowel pin of crankshaft setted about 3° with vertical center line.
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.
Install the new O-rings (A).
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 paint marks of the chain.
Order : Crankshaft sprocket → Timing chain guide → Intake camshaft sprocket → Exhaust camshaft sprocket.
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)
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 camshaft.
Install the timing chain cover.
