Crankshaft, Assembly Overview

Crankshaft, assembly overview

Note:
^ In vehicles with Direct Shift Transmission, a needle bearing must be installed at rear in crankshaft.





1. 65 Nm plus an additional 90° (1/4 turn)
^ Replace
^ Fully threaded
^ Only tighten crankshaft to 65 Nm to measure radial play. Do not rotate further.
2. Bearing cap
^ Bearing cap 1: Belt pulley side
^ Retaining tabs of bearing shells and cylinder block/bearing caps must lie above one another
3. 10 Nm plus an additional 90° (1/4 turn)
^ Replace
4. Sensor wheel
^ For Engine Speed (RPM) Sensor G28
^ Replace sensor wheel every time bolts are loosened
^ Only possible to install in one position - Bores are offset
5. Crankshaft
^ Axial play new: 0.07 to 0.23 mm Wear limit: 0.30 mm
^ Check radial clearance with Plastigage(R) 0.017 to 0.037 mm Wear limit: 0.07 mm
^ Do not turn crankshaft when measuring radial play
6. Thrust washers
^ For bearing 3
7. Bearing shell for cylinder block
^ With lubricating groove
^ Classification for replacement part ordering => Identification on crankshaft bearing, top
^ Do not interchange used bearing shells (mark)
8. Chain sprocket
^ For oil pump drive
9. Bearing shell for bearing cap
^ Without lubricating groove
^ Do not interchange used bearing shells (mark)

Sensor wheel, removing and installing





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

Note:
^ 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 the sensor wheel is only possible in one position, the bore holes are shifted.
