- Loosen bolts for engine timing module.

CAUTION!
Make sure that the input shafts for oil and coolant pumps do not fall off cylinder block.

- Carefully pull engine timing module off inclined splines.

Installing

- Install guide pins (T10200) into threaded holes of upper section of bearing bracket as shown.





- Place engine timing module on guide pins.

• Observe the following adjustment marks and requirements and note the inclined splines while doing so (wheels turn slightly when sliding on the module):





- Holes on splines of crankshaft gear and input gear for oil pump must align as shown.





- Input shaft fits only in one position. Rotate shaft so that the wide cut out in the hole aligns to the broad tooth on the pin.





- The hole on the drive wheel of cylinder bank 1 must align with cast tab on inside of engine timing module as shown.





- Carefully slide engine timing module on guide pins in its seat, note the mentioned adjustment markings while doing so.

- Center the engine timing module by placing the pressure piece of assembly tool (T10208/3) on generator shaft end - A -. Pressure piece must be able to be set into countersink without force.





- Replace the individual guide pins with bolts and tighten bolts to 60 Nm.

- Now tighten bolts to 150 Nm + 1/4 turn. (90°) turn.
