Removal Procedure
1. Turn the crankshaft and position the No. 1 cylinder piston
at BTDC 30°.
2. Remove the alternator.
3. Remove the chain tensioner.
4. Remove the cylinder head front cover and the upper guide
rail.
6. Unscrew the exhaust camshaft sprocket bolt and remove
the sprocket.
7. Separate the chain from the intake camshaft sprocket and
put the chain not to be dropped into timing case. 5. Put the alignment marks (arrows) on the camshaft sprocket
(2, 5) and the timing chain (6).

8 . Unscrew the intake side bolts (8, 11, 13, 14) and the exhaust
side bolts (1, 4, 6, 7).
9. Loosen the remaining bolts and unscrew the intake and
exhaust side camshaft bearing cap bolts.
Notice
Number the camshaft bearing cap bolts when removing
them, so that they don’t get mixed up.
10. Remove the intake and exhaust camshafts.
Installation Procedure
1. Turn the crankshaft and position the No. 1 cylinder piston
at BTDC 30°.
Notice
Turn the crankshaft in the direction of engine rotation.
3. Turn the camshaft using the wrench (special tool) so that
the intake camshaft adjustment hole lines up with the cylinder
head upper side (3 o’clock direction at the intake, 9 o’clock
direction at the exhaust).
Notice
Turn the crankshaft and adjust it to OT so that No. 1 cylinder’s
piston would be at TDC. Install the bearing caps according to the numbers on the
bearing caps.
Tightening Torque 22.5 - 27.5 Nm 2. Install the exhaust camshaft bearing caps (2, 3, 5) and the
intake camshaft bearing caps (9, 10, 12). Tighten the bolts
with specified torque and install the remaining bearing caps.

4. Turn the intake camshaft adjuster to the direction of camshaft
rotation by hard until it stops and then install the chain.
Notice
lMake sure that the camshaft sprocket and timing chain
are aligned with marks.
lIntake camshaft adjuster should be in retarded position.
5. Install the chain on the exhaust sprocket and tighten the
sprocket bolts.
Notice
7. Rotate the crankshaft 2 revolutions and check followings:
- TDC of no. 1 cylinder : OT
- Alignment between camshaft adjustment hole and
cylinder head surface.
- Alignments between timing chain and sprocket marks.
Notice
lTurn the crankshaft in the direction of engine rotation.
lRead just if not aligned. 6. Install the chain tensioner and tighten it as specified.
Notice lMake sure that the camshaft sprocket and timing chain
are aligned with marks.
lReplace the sprocket bolt with new one.
