Crankshaft Overview

Crankshaft Overview


• If the crankshaft was removed, a new intermediate sprocket with a coating must be installed and the hub including the bolt and axial bearing discs must be replaced. Otherwise the backlash will be incorrect.






1 Bearing Shells 1, 2, 4 and 5

• For the bearing caps without oil grooves.

• For the cylinder block with oil grooves

• Do not interchange used bearing shells (mark them).

2 Bolt

• 65 Nm + an additional 90° (1/4) turn.

• Always replace.

• Tighten to 65 Nm to measure the radial play, do not tighten further.

3 Bearing Cap

• Bearing cap 1: belt pulley side

• Bearing cap 3 with notches for thrust washers

• Retaining tabs on bearing shells and cylinder block/bearing caps must align above one another.

4 Bearing Shell 3

• For the bearing cap without a oil groove.

• For the cylinder block with a oil groove.

5 Thrust Washer

• For bearing cap 3.

• Observe the locating point.

6 Crankshaft

• Refer to the caution at the top.

• Axial play:

New: 0.07 to 0.17 mm

Wear limit: 0.37 mm

• Check the radial clearance using Plastigage(R):

New: 0.03 to 00.08 mm

Wear limit: 0.17 mm

• Do not rotate the crankshaft when measuring the radial play.

• Crankshaft dimensions, refer to => [ Crankshaft Dimensions ] Crankshaft Dimensions.

7 Thrust Washer

• For cylinder block, bearing 3.
