2. If the bearings are not replaced with new ones, ensure that they are installed in their original positions on the corresponding connecting rods.
3. The pistons with connecting rods are installed in the corresponding cylinders on top of the cylinder block.
4. Arrange the piston ring locks as follows:
- top: 150° one way from the oil ring spiral expander joint;
- central: 150° to the other side from the joint of the spiral expander of the oil scraper ring;
- lower: spiral oil ring expander opposite the marked front side of the piston;
- oil scraper ring, intermediate rings: 25 mm on each side of the spiral expander gap.
5. Lubricate the piston and piston rings with engine oil.
6. Install the universal piston ring compressor and prepare to install the first piston into the cylinder. Check: the connecting rod and piston groups must match the cylinder numbers, the connecting rod must be installed in the correct direction, the front of the piston must be located towards the front of the engine (there is a corresponding arrow or mark on the piston bottom).
7. Lubricate the piston skirt and insert the connecting rod and piston group into the cylinder bore so that the lower part of the piston ring compressor is located near the cylinder block.
8. Tap the piston gently but firmly with the hammer handle to seat the piston into the cylinder.
9. Lubricate the connecting rod journals with engine oil and turn the crankshaft so that the connecting rod journals are in the most convenient position for installing the connecting rods on them.
10. Wipe the connecting rod bearing cap and the outside of the bearing shell and install the bearing shells in place so that the bearing shell locating tab fits into the locating groove in the connecting rod cap.
11. Lubricate the bearing and install the cover on the connecting rod.
12. Install the connecting rod nuts in place.
13. Tighten the nuts with a torque wrench to the specified torque.
14. Once all connecting rods are in place, rotate the crankshaft to ensure that the shaft rotates freely without binding.
