6. Check the timing.

New

After approx. 20,000km

ATDC 11.33°

ATDC 12°

Notice

If timing is out standard, the camshaft should be checked
for wear and the timing chain for stretch. If a difference of
more than 4° exists, the timing chain should be replaced.

7. Replace the gasket and install the cylinder head cover.

Tightening Torque

10 Nm

Measurement Procedure

1. Remove the cylinder head cover.

2. Rotate the engine in the direction of engine rotation until

the intake valve of NO. 1 cylinder is completely closed. The
cam lobe faces up (arrow).

Notice

Do not rotate the engine at the bolt of the crankshaft
sprocket. Do not rotate the engine in the opposite direction
of engine rotation. If do, this will cause serious measuring
errors.

3. Install the dial gauge holder and dial gauge (7) with the

extension (8) to the cylinder head and position the tracer
pin (9) onto the valve tappet (intake valve of cylinder NO.1)
with a preload of min. 3mm.

Notice

The tracer pin should be positioned exactly vertical.

4. Set the dial gauge to ‘0’.

5. Rotate the engine further in direction of rotation until the

dial gauge has moved back by 2mm (valve lift) to 1mm.

engine rotation.

In this position, the markings of the camshaft/camshaft
bearing cap (arrow) must be aligned.

2. Place alignment marks on the camshaft sprocket and timing

Remove the camshaft bearing cap bolts of 1(dark arrow)
first and then remove the bolts of 2 (light arrow) one
revolution in stages until the counter-pressure is released.
In order to avoid damaging the camshaft, it is essential to
adhere to the removal order for the camshaft bearing caps.
