1. Clean off any carbon deposits along the edges of the cylinder block beds. Clean the oil grooves in the beds from deposits.
2. Install the main bearing shells in the cylinder block bed in accordance with the marks made during disassembly. When installing the liners, their locking tabs must enter the grooves of the beds.
3. Lubricate the bearings with engine oil.
Attention! After installing the liners in the bed, their ends protrude slightly outward, therefore, to correctly orient the liners during the final tightening of the bearing cap bolts, make sure that the protrusion of both ends is the same.
4. Install the crankshaft into the cylinder block.
5. Lubricate the thrust half rings with engine oil. Pay attention to the grooves of the half rings: these sides of the half rings should be installed towards the crankshaft cheeks.
6. Install the steel-aluminum half ring (white color) from the front side of the middle bed (from the camshaft drive side)...
7. ...metal-ceramic (yellow color) - on the other side of the bed.
8. Rotate the half rings so that their ends are flush with the ends of the bed.
9. Insert the liners into the main bearing caps in accordance with the marks made during disassembly. In this case, the locking tabs of the liners must enter the grooves of the covers.
10. Lubricate the bearings with engine oil.
11. Install the covers according to the marks. The covers are marked (notched) according to the cylinder number. The exception is the fifth cover, which has two marks, just like the second one. On the second cover there are two threaded holes 1 for the oil receiver mounting bolts. In this case, the cylinder numbers are counted from the camshaft drive side, and the covers are installed with marks 2 in the opposite direction from the oil filter nipple 3.
Caution: Use a soft-faced hammer made of brass, lead or polyurethane to install the crankshaft main bearing caps. Installing the covers by tightening the fasteners is prohibited, as this will damage the seating surfaces of the covers and the cylinder block.
12. Lubricate the threads and ends of the heads of the cover mounting bolts with engine oil.
13. Tighten the bolts to the specified torque (see appendix 1) in the following order: first tighten the bolts of the third cover, then the second and fourth, then the first and fifth. After tightening the bolts, turn the crankshaft 2-3 turns - it should rotate easily, without jamming.
14. For ease of installation, lubricate the oil pump gasket with a thin layer of grease and "glue" it to the block. Remove excess grease.
15. Install the oil pump and tighten its mounting bolts (see "Removing and installing the oil pump").
16. For ease of installation, lubricate the rear oil seal retainer gasket with a thin layer of grease and "glue" it to the block. Remove excess grease.
17. Install the rear oil seal holder and tighten the bolts that secure it.
18. Insert the connecting rod into the piston in accordance with the previously made marks so that the mother number on the connecting rod is facing the front of the piston (the arrow stamped on the top of the piston bottom points in this direction).
19. Lubricate the piston pin with engine oil and insert the pin into the piston and connecting rod.

20. Install the snap rings on both sides of the pin. In this case, pay attention to the fact that the rings must be clearly installed in the piston grooves.
Warning! A ring that is not properly seated in the piston groove will pop out of the groove when the engine is running and cause serious damage.
21. Install the oil scraper ring expander onto the piston.
22. Install the piston rings. It is recommended to do this using a special puller. If it is not there, install the rings on the piston, carefully spreading the ring locks.
23. The order of installing the rings: the oil scraper ring is installed first (the ring lock must be on the opposite side from the release spring lock), then the lower compression ring, and lastly the upper compression ring.
24. Please note that the rings may have the inscription "GOE" or "TOP" stamped on them. The rings should be installed with this inscription facing up (to the piston bottom).
25. Turn the rings in the piston grooves and make sure they rotate easily. If any ring does not turn or sticks, it must be replaced.
26. Rotate the rings on the piston so that their locks are located at an angle of 120° to each other.
27. Carefully wipe the crankshaft connecting rod journals with a clean cloth.
28. Carefully wipe the cylinder mirrors with a clean cloth and lubricate them with engine oil.
29. Insert the bearing shell into the connecting rod in accordance with the previously made marks so that the bearing shell tab fits into the groove in the connecting rod. After this, lubricate the bearing and piston with engine oil.
30. Place a special mandrel on the piston to compress the piston rings and carefully lower the connecting rod into the cylinder. It is recommended to pre-rotate the crankshaft so that its connecting rod journal, on which the connecting rod and piston group is mounted, is set to BDC. The arrow on the piston bottom should point toward the front of the engine (towards the camshaft drive).
31. Press the mandrel firmly against the block and use the hammer handle to push the piston into the cylinder. If the mandrel does not fit tightly against the cylinder block, the piston rings may break.
32. Install the lower connecting rod head onto the crankshaft journal.
33. Insert the insert into the connecting rod cap in accordance with the previously made marks so that the tab of the insert enters the groove in the cap. After this, lubricate the liner with engine oil.
34. Install the connecting rod cover. The connecting rod markings on the cap and the lower connecting rod head must be on the same side.
35. Tighten the cover mounting bolts to the specified torque (see appendix 1). Install the remaining pistons in the same manner.
36. Install the oil receiver and tighten the three bolts that secure it.
37. Apply anaerobic thread locker to the flywheel mounting bolts. Install the flywheel, lock plate and tighten the flywheel mounting bolts (see "Removal, installation and defect detection of the flywheel").
38. For ease of installation, apply a thin layer of consistent grease to the surface of the block and "glue" the oil pan gasket to it.
39. Install the oil pan and tighten its mounting bolts (see appendix 1). Next, assemble the engine in reverse order. Installation of the cylinder head is described in the subsection "Replacing the cylinder head gasket", camshaft drive belt - in the subsection "Replacing the timing belt and tension roller".
