Valve Timing

• For verifying or adjusting the valve timing of the gear drive the timing marks have to be

aligned as shown below (refer to the workshop manual for details).

• All helical gears except for the fuel high-pressure pump gear have a punch mark as

timing mark. However, the punch marks on the crankshaft gear and on the fuel-high-

pressure pump gear can only be seen when the friction gears are removed.

NOTE: The timing mark of each gear can be aligned easily, if paint is applied to the punch

marks.
