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 exhaustside 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. Notice

4. Turn the intake camshaft adjuster to the direction of camshaftrotation by hard until it stops and then install the chain. Notice
Make sure that the camshaft sprocket and timing chain are aligned with marks.
Intake 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 andcylinder head surface.
- Alignments between timing chain and sprocket marks. Notice
Turn the crankshaft in the direction of engine rotation.
Read just if not aligned.
6. Install the chain tensioner and tighten it as specified.
Notice

Make sure that the camshaft sprocket and timing chain are aligned with marks.
Replace the sprocket bolt with new one.

Adjustment Procedure
1. Position the No.1 cylinder to BTDC 30° .
2. Remove the chain tensioner.
3. Remove the exhaust camshaft sprocket.
4. Align the intake and exhaust camshaft flange hole with the cylinder head upper surface.
Intake Side : 3 o ’clock direction
Exhaust Side : 9 o ’clock direction
5. Secure the intake and exhaust camshaft.
6. Position the piston of No.1 cylinder at TDC (OT) by turning the crankshaft.
7. Turn the camshaft adjuster of the intake camshaft to the left as much as possible (cam adjuster ‘retarded ’ position).
8. Install the chain to the intake camshaft sprocket.
Notice
Timing chain must be placed on the guide rail in gear case
cover.

Inspection
1. Position the No.1 cylinder piston to TDC (OT) by turning the crankshaft. Notice When the OT mark on vibration damper is aligned with timing
gear case cover, the intake and exhaust cam of cylinderwill make the slope to the center and will face up. In this
way, the adjustment hole of the intake and exhaust camshaft will match in line with the cylinder head upper end, at 3
o’clock, and 9 o ’clock direction each other.
2. Check the timing as below procedure; - Check if the camshaft adjustment hole is positioned to 3 o’clock direction at the intake side and to 9 o ’clock
direction at the exhaust side, respectively and align withthe cylinder head mating surface.
- At this condition, check if the OT mark on vibration damper aligns with the marker on the timing gear case.

11. Check the camshaft timing.The sprocket bolt is designed to be used only once, so replace with new one.
10. Install the chain tensioner.
