- When replacing the crankshaft bearing upper, select a bearing with the size corresponding to the crankshaft journal diameter in the table below.
- The crankshaft bearing upper has an identification mark at the illustrated position in the figure. CYLINDER BLOCK SPECIFICATIONS Cylinder block Crankshaft bearing Identification mark Journal diameter mm (in) Identification mark 1 56.000 - 56.006 (2.2047 - 202049) 1 2 56.006 - 56.012 (2.2050 - 2.2051) 2 3 56.012 - 56.018 (2.2050 - 2.2054) 3
- Install the selected crankshaft bearing upper.

- Install the crankshaft bearing cap with reference to the identification mark as illustrated in the figure.
- Make sure that the underhead length of the bolt is at or below the limit before installing the crankshaft bearing cap bolt. If the length exceeds the limit, replace the bolt with a new one. Limit: 75.5 - 76.5 mm (2.972 - 3.012 inch)
- Apply engine oil to the threaded portion and seat surface of the bolt.
- Tighten crankshaft bearing cap bolts to the torque of 26.5 ± 2.0 N.m (20 ± 1 ft-lb) according to the tightening order. CAUTION: When the tightening angle is smaller than the specified tightening angle, the appropriate tightening capacity cannot be secured. When the tightening angle is larger than the specified tightening angle, remove the bolt to start from the beginning again according to the procedure.
- Use special tool Angle gauge (MB991614) to tighten bolts 45° according to the tightening order.
- Check end play of the crankshaft after installing the crankshaft bearing cap. If the end play exceeds the limit, replace the thrust bearing. Standard value: 0.05 - 0.25 mm (0.002 - 0.010 inch) Limit: 0.4 mm (0.016 inch)
