2. When boring the cylinders, all crankshaft main bearing caps must be in place, and the cap mounting bolts must be tightened to the specified torque.
3. The cylinder diameter after boring should be 0.03 mm less than the final diameter - this is an allowance for honing the cylinder walls.
4. Honing is recommended to be carried out in two stages, first with relatively coarse stones with a grain size of 100 mesh (0.12 mm), then finally with stones with a grain size of 220-240 mesh (0.05 mm). The hone grid should be located at an angle of 45 degrees to the axis of the cylinder. The tops of the hone marks should be clearly visible, but not have sharp tops (plateau honing).

5. After honing, mark the piston with the cylinder number where it will be installed.
6. Thoroughly rinse the cylinder walls until all abrasive is removed.
7. Lubricate the cylinder walls with clean engine oil to prevent rust.
8. If boring the cylinders to the repair size is not required, remove polished areas from the cylinder walls using a hand hone.
