Removal & Installation Procedure
1. Turn the crankshaft to the direction of engine rotation
and position the no.1 cylinder piston at TDC which the
camshaft is positioned at OT.
2. Remove the cylinder head front cover.
3. Paint the alignment marks (arrows) on the intake and
exhaust camshaft sprocket and the timing chain.

Inspection
1. Position the No.1 cylinder piston to TDC (OT) by turn-
ing the crankshaft.
Notice:When the OT mark on vibration damper is
aligned with timing gear case cover, the intake and ex-
haust cam of cylinderwill make the slope to the center
and will face up. In this way, the adjustment hole of the
intake and exhaust camshaftwill match in line with the
cylinder head upper end, at 3 o’clock, and 9 o’clock di-
rection each other.
2. Check the timing as below procedure;
-- Check if the camshaft adjustment hole is posi-
tioned to 3 o’clock direction at the intake side and
to 9 o’clock direction at the exhaust side, respec-
tively and align with the cylinder head mating sur-
face.
-- At this condition, check if the OT mark on vibration
damper aligns with the marker on the timing gear
case.
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.
DIntake Side : 3 o’clock direction
DExhaust Side : 9 o’clock direction
5. Align the holes on intake and exhaust camshaft to the
hole on cylinder head. Insert the holding pin
DW110-- 120 into the holes.
6. Secure the intake and exhaust camshaft.
7. Position the piston of No.1 cylinder at TDC (OT) by
turning the crankshaft.
8. Turn the camshaft adjuster of the intake camshaft to
the left as much as possible (cam adjuster ‘retarded’
position).
9. Install the chain to the intake camshaft sprocket.
Notice:Timing chain must be placed on the guide rail in
gear case cover.
