Timing Chain: Installation
- The key (A) of crankshaft should be aligned with the timing mark (B) of block. As a result of this, the piston of No. 1 cylinder is placed at the top dead center on compression stroke.
- Install the tensioner adapter assembly (A).
- Install the crankshaft sprocket (A). (LH camshaft drive).
- Install the LH timing chain (A).NOTE: 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 → Intake camshaft sprocket.
When installing the timing chain, be sure that the timing mark of each sprocket is matched with the timing mark (color link) of the timing chain. - Install the LH timing chain guide (A).
Tightening torque:
19.6 - 24.5 N.m (2.0 - 2.5 kgf.m, 14.5 - 18.1 lb.ft)
- Install the LH timing chain auto tensioner (A) and LH timing chain tensioner arm (B).
Tightening torque:
A: 9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb.ft)
B: 18.6 - 21.6 N.m (1.9 - 2.2 kgf.m, 13.7 - 15.9 lb.ft)
NOTE: Always use new LH timing chain tensioner. - Install the LH timing chain cam to cam guide (A).
Tightening torque:
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb.ft)
- Pull out the pins of LH timing chain auto tensioner.
- Install the crankshaft sprocket (A) (Oil pump drive).
- Install the oil pump chain sprocket (A) and oil pump chain (B).
Tightening torque:
19.6 - 24.5 N.m (2.0 - 2.5 kgf.m, 14.5 - 18.1 lb-ft)
- Install the oil pump chain tensioner assembly (A).
Tightening torque:
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb.ft)
- Install the camshaft sprocket (A). (RH camshaft drive)
- Install the RH timing chain (A).NOTE: To install the timing chain with no slack between each shaft (cam, crank), follow the procedure below:
Crankshaft sprocket →Timing chain guide → Intake camshaft sprocket → Exhaust camshaft sprocket.
When installing the timing chain, be sure that the timing mark of each sprocket is matched with the timing mark (color link) of the timing chain. - Install the RH timing chain guide (A).
Tightening torque:
19.6 - 24.5 N.m (2.0 - 2.5 kgf.m, 14.5 - 18.1 lb.ft)
- Install the RH timing chain auto tensioner (A) and the RH timing chain tensioner arm (B).
Tightening torque
A: 9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb.ft)
B: 18.6 - 21.6 N.m (1.9 - 2.2 kgf.m, 13.7 - 15.9 lb.ft)
NOTE: Always use new timing chain tensioner. - Install the RH timing chain cam to cam guide (A).
Tightening torque:
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb.ft)
- Pull out the pins of RH timing chain auto tensioner.
- After rotating the crankshaft 2 revolutions in regular direction (clockwise viewed from front), confirm the timing mark.

NOTE:- Always turn the crankshaft clockwise.
- Turning the crankshaft counterclockwise before building up oil pressure in the hydraulic timing chain tensioner may result in the chain disengagement from the sprocket teeth.
- Install the timing chain cover.
(Refer to Timing System - "TIMING CHAIN COVER ")
- Install in reverse order of removal.NOTE: Install the timing chain to the specified torque.
- Fill with engine coolant.
(Refer to Cooling System - "COOLANT ")
- Start engine and check for any leaks.
- Recheck engine coolant level.
