Tighten crankshaft bearing cap bolts to the torque of 26.5 ± 2.0 Nm (20 ± 1 ft-lb) according to the tightening order.





CAUTION
^ If the tightening angle is less than 45°, tightening performance may not be secured. Use caution to the tightening angle during tightening.
^ If the tightening angle becomes more than 45°, completely loosen bolts and start tightening over again according to the procedure.

Use special tool 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.
