Crankshaft Main Bearing

Crankshaft, Tightening Sequence:





Tighten the crankshaft bolts in the sequence - 1 to 5 -.

Tighten the bolts - 1 through 10 - and - arrows A - hand-tight.

Tighten the bolts - 1 through 10 - to 65 Nm.

Tighten the bolts - 1 through 10 - 90° further using a rigid wrench.

Tighten the bolts - arrows A - to 20 Nm.

Tighten the bolts - arrows A - 90° further using a rigid wrench.

Crankshaft Dimensions:

(Dimensions in mm)





1) The preparation of worn crankshafts is not provided.

Axial Clearance:
New 0.070 to 0.231 mm
Wear limit 0.30 mm

Radial Clearance:
Install the crankshaft bearing cover and tighten it to 60 Nm. Do not turn the crankshaft while doing this.
New 0.017 to 0.037 mm
Wear limit 0.15 mm

Crankshaft Bearing Shell Allocation:

The bearing shells are allocated to the cylinder block with the correct thickness at the factory. Colored spots serve to identify the bearing thicknesses.

The code letters on the lower contact surface or on the top of the cylinder block identify which bearing shell and where it must be mounted on the cylinder block (upper bearing shell).

The code letters on the crankshaft identify which bearing shells and where they must be installed in the bearing cover (lower bearing shell).

The first letter is for bearing cover one, the second for bearing cover two, etc.

Cylinder Block Bearing Shell Identification





The cylinder block identification may be located either on the oil pan sealing surface or on the top (transmission side) of the cylinder block.

The identification on the cylinder block is for the upper bearing shell.





Note the letters and then match it to the color identification in the table.

Bearing Cap Bearing Shell Identification





The identification on the crankshaft is for the lower bearing shell.

Note the letters and then match it to the color identification in the table.
