Removing and installing sensor rotor
–  Always replace the sensor rotor -2- each time the bolts -1- are slackened.
  Note
t  After being attached a second time, the attachment point of the recess head screws in the sensor rotor is sufficiently misshapen that the bolt heads rest against crankshaft -3--arrows- and the sensor rotor is positioned loosely below the screws.
t  It is only possible to install the sensor rotor in one position, the holes are offset.

Assign crankshaft bearing shells to the cylinder block
The cylinder block bearing shells are allocated with the right thickness at the works. Coloured points on the bearing shell are used to mark the bearing shell thickness.
  Note
t  The arrow faces towards the belt pulley side.
t  The markings are visible without removal of the oil pan.
The bearing shell is to be used at the location which is marked with letters, on the lower sealing surface of the cylinder block.
