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.

1. Place the supporting bar (12) and the slide (9) at thecamshaft bearing cap (Nos 1 & 7/8&14) and tighten them with the bearing cap bolt. Installation Notice
2. Turn the crankshaft to position the each cylinder piston at TDC.
5. Install the engine lock to the ring gear to prevent the crankshaft from rotating.
6. Blow up with compressed air. Notice

Remove the valve spring only at TDC.
Always rotate the crankshaft by holding the chain to prevent from timing chain damage and tangling, and for smooth rotation.
3. Remove the valve tappet (1) using the magnetic finger.
