1. Remove the cylinder head, sump and oil pump.
2. If there is carbon on the top of the cylinder, remove it with a soft scraper. The presence of a step in the upper part of the cylinder indicates excessive wear of the cylinder and the need to bore the engine cylinders.
3. Using a hammer and punch or paint, mark the position of the connecting rod cap and cylinder number (the picture shows cylinder #3).
4. Turn the crankshaft so that the pistons of the 1st and 4th cylinders are at BDC.
5. Turn away nuts of fastening of a cover of the bottom head of a rod of the first cylinder. Remove the lower connecting rod cover.
6. To prevent the possibility of damage to the crankshaft journals by the connecting rod studs, wrap the studs with any soft material or put appropriate tubes of soft material on them.
7. Using a hammer handle, push the piston up the cylinder block and remove it from the cylinder block.
8. Install the connecting rod cap on the lower head of the connecting rod and screw it with nuts, which will allow you to keep them as a set and not confuse them.
9. Remove the piston of the fourth cylinder in the same way.
10. Rotate the crankshaft 180°to set the 2nd and 3rd cylinder pistons to BDC and remove the pistons in the same way.
