MAIN BEARING CAP BOLTS
- Apply engine oil to the upper bearing and install the crankshaft onto the cylinder block.





- Install the 2 upper thrust washers onto the No. 2 journal position of the cylinder block.
Push the crankshaft toward the front (rear) side.
Install the 2 upper thrust washers with the oil grooves facing outward.





- Install the 2 lower thrust washers onto the No. 2 bearing cap with the grooves facing outward.





- Examine the front marks and numbers, check the sequence number is as shown in the illustration and install the bearing caps on the cylinder block.
- Apply a light coat of engine oil to the threads of bearing cap bolts.
- Temporarily install the 8 main bearing cap bolts in the inside positions.





- Install the main bearing caps. Tighten the 2 bolts for each bearing cap until the clearance between the bearing cap and the cylinder block is under 6 mm (0.23 in.).





- Using a plastic-faced hammer, lightly tap the bearing cap to ensure a proper fit.
- Apply a light coat of engine oil to the threads of main bearing cap bolts.





- Install the 16 main bearing cap bolts. Using several steps, tighten the bolts uniformly in the sequence shown in the illustration.
Torque: 61 Nm (622 kgf-cm, 45 ft-lbf)





- Mark the front side of the bearing cap bolts with paint.
- Retighten the bearing cap bolts 90° in the sequence as shown.
- Check that the painted mark is now at a 90° angle from the front.
- Check that the crankshaft turns smoothly.





- Using several steps, tighten the 8 main bearing cap bolts uniformly in the sequence shown in the illustration.
Torque: 25 Nm (255 kgf-cm, 18 ft-lbf)
