Crankshaft frame - bolt tightening sequence and torque
Replace the camshaft frame mounting bolts. Install both centering bushings in the cylinder head. Tighten the bolts in the sequence "1...16" in 3 stages as follows.
- 1. Tighten to 30 Nm.
- 2. Tighten to 50 Nm.
- 3. Turn 90° further.
Accessory of main bearing shells installed in the cylinder block
At the factory, bearing shells of the correct thickness are installed in the cylinder block. Colored dots on the bearing shell are used to mark the thickness of the bearing shells. The "arrow" points towards the belt pulleys.
P. II
The belonging of the bearing shells to the cylinder block is indicated by a letter next to the corresponding bearing.

Compliance of main bearing shells installed in the crankshaft frame
At the factory, bearing shells of the correct thickness are installed in the bearing caps. Colored dots on the bearing shell are used to mark the thickness of the bearing shells. The correspondence of the bearing shells to the crankshaft is marked on the edge of the crankshaft with a letter sequence. The first shell "I" "arrow" is marked in color for bearing 1.
