Sensor wheel, removing and installing





- Always replace sensor wheel - 2 - whenever bolts are removed - 1 -.

After tightening a second time, the attachment point of the countersunk screws of the sensor wheel are so deformed that the screw heads lie on the crankshaft - 3 - - arrows - and the sensor wheel is loose underneath the screws.

Installation of sensor wheel is only possible in one position - the bores are offset.

Allocation of crankshaft bearing shells for cylinder block





The cylinder block is allocated with bearing shells of the correct thickness in the factory. Colored spots serve to identify the bearing thicknesses.

Arrow points in direction of travel.

The letters marked on lower sealing surface of cylinder block identify which bearing shell must be installed in which location.





The crankshaft bearing shells in the bearing caps are only available as a replacement part with a "yellow" color marking.
