REMOVAL SERVICE POINT



<<A>> CRANKSHAFT REMOVAL


When temporarily placing the crankshaft with the crankshaft sensing ring attached, temporarily place it on a V-block to prevent teeth of the sensing ring from deforming.
note If a tooth bends, be sure to replace the crankshaft sensing ring with a new one.

INSTALLATION SERVICE POINTS



>>A<< CRANKSHAFT SENSING RING INSTALLATION



Tighten crankshaft sensing ring bolts to the torque of 11 ± 1 N·m in the tightening order shown in the illustration.

>>B<< THRUST BEARING INSTALLATION


1.Install the thrust bearing on the No. 3 bearing on the cylinder block side. Application of engine oil makes the installation easy.

2.Install the thrust bearing so that the grooved side is on the crankshaft weight side.

>>C<< CRANKSHAFT BEARING UPPER INSTALLATION




1.When replacing the crankshaft bearing upper, select a bearing with the size corresponding to the cylinder block journal diameter in the table below.
The crankshaft bearing upper has an identification mark at the illustrated position.

>>E<< CRANKSHAFT BEARING CAP / CRANKSHAFT BEARING CAP BOLT INSTALLATION



1.Install the crankshaft bearing cap with reference to the identification mark as illustrated.

2.Make sure that the shank 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
3.Apply engine oil to the threaded portion and seat surface of the bolt.
4.Tighten crankshaft bearing cap bolts to the torque of 26.5 ± 2.0 N·m according to the tightening order.

5.
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.

6.Check axial play of the crankshaft after installing the crankshaft bearing cap. If the axial play exceeds the limit, replace the thrust bearing.
Standard value: 0.05 - 0.25 mm
Limit: 0.4 mm
