1. Apply a coat of engine oil to the connecting rod bearing shells.

2. Install the upper and lower connecting rod bearings.

3. Establish the lower loose leaves of rod bearings.

4. Check clearances in connecting rod bearings.

5. Cut plastic measuring strips to a length equal to the width of the bearings. Position them along the axis between the connecting rod bearing journals with the connecting rod bearing shells.

6. Install the connecting rod bearing caps.

7. Tighten the connecting rod bearing cap screws to 25 Nm.

8. Tighten the screws of the crankshaft cover at an angle of 30°+ 15°.

9. Remove the connecting rod bearing caps.

10. Measure the width of the flattened plastic layer with a ruler.
