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

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.
