Removal the crankshaft (Opel Insignia A)

Checking the axial play of the crankshaft

1. Place a dial indicator on the end of the crankshaft.

2. Using careful movements, move the crankshaft forward and backward in the axial direction to determine the axial play of the crankshaft.

3. Make sure that the crankshaft axial clearance does not exceed the specified value.

4. If the axial clearance value is too large, check the crankshaft thrust bearings and the condition of the crankshaft thrust surfaces for wear and/or excessive runout.

5. If necessary, replace the thrust bearings or crankshaft.

Removal the crankshaft main bearing shells

1. Prepare a piece of cardboard or something similar, numbered 1 through 4 to mark the crankshaft main bearing shells. The crankshaft main journals are numbered starting from the front of the engine.

2. Remove the upper crankshaft main bearing shells from the cylinder block. Pay attention to the position of the thrust bearing (1) on the third main support (2).



3. Place the upper main bearing shells on a piece of cardboard in the correct order. Note that the third journal bearing is also a thrust bearing.



4. Remove the lower crankshaft bearing shells from the bearing caps.
