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.
l
Intake Side : 3 o’clock direction
l
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.
Tools Required
104 589 01 01 00 Spanner
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 cylinder
will 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 with
the cylinder head mating surface.
-
At this condition, check if the OT mark on vibration
damper aligns with the marker on the timing gear case.
