1. Remove the crankshaft from the cylinder block.
2. If equipped, check that the oil sprayers are installed in the cylinder block.
3. Clean the back of the bushing and its mounting location in the cylinder block and main bearing caps. Install the earbuds in place.
4. Install the upper thrust half rings to adjust the crankshaft end play as follows:
- on 4-cylinder engines on the central main bearing No. 3;
- on 5-cylinder engines on the main bearing No. 4;
- on 6-cylinder engines on the main bearing No. 5.
5. Lubricate the bearing surface with clean engine oil and install the crankshaft into the engine block.
6. Lubricate the lower bearing shells in the main bearing caps with clean engine oil and check that the tabs on the bearing shells are in the cap grooves.
7. Install the main bearing caps as marked. Check that the thrust washers are on the correct main bearing cap.
8. Lubricate the crankshaft bearing cap bolts with clean engine oil, insert them into the caps and tighten by hand. On 6-cylinder DOHC engines, the main bearing cap bolts without oil catcher bolt threads in the head are installed on the drive chain side. Install the oil pickup tube mounting bracket before installing the bolts.
9. Gradually and in a diagonal sequence from the center to the edge, tighten the bearing cap bolts in several steps (see fig. Tightening the main bearing cap bolt to the required torque, Tightening the main bearing cap bolt by tightening it to a certain angle).
10. Check that the crankshaft rotates smoothly and without binding.
11. Install a new o-ring in the crankshaft rear cover, then install the cover with a new gasket or a thin layer of sealant on the cylinder block (see fig. Applying a thin layer of sealant to the mating surface of the rear crankshaft cover on 6-cylinder DOHC gasoline engines, Tightening the rear crankshaft cover mounting bolts on 6-cylinder DOHC engines).
12. Install pistons with connecting rods.
13. Further assembly is carried out in the reverse order of disassembly, taking into account the following points.
14. On 4-cylinder engines, install the crankshaft sprocket, drive chain, drive chain cover, oil pan, and flywheel/drive plate.
15. On SOHC 6-cylinder gasoline engines, install the crankshaft sprocket, drive chain, lower drive chain cover, oil pump, oil pan, and drive flywheel/plate.
16. On 6-cylinder DOHC gasoline engines, install the crankshaft sprocket, drive chain, lower drive chain cover, oil pump, oil catch plate, oil pan, and drive flywheel/plate.
17. On diesel engines, install the crankshaft sprocket, drive chain, drive chain cover, oil pump, oil catch plate, oil pan and drive flywheel/plate.
