- Arrow on the piston bottom (either applied or on a new connecting rod with an arrow) must face the front of the engine.
- The "VORN" mark on the connecting rod should be facing the front of the engine. There is a small protrusion on the connecting rod near the bearing that should be located closer to the front of the engine.
- The cylinder number indices (Fig. 22) on the connecting rods and bearing caps must match.
- Using snap ring pliers, insert one of the snap rings into the piston bore. The ring should fit snugly into the groove.
- Heat the piston either on an electric stove or in hot water to about 80°C, lubricate the pin and the piston hole with motor oil and press the pin with your thumb into the correctly connected piston and connecting rod until the pin rests against the retaining ring on the other side. Install the second retaining ring in the piston hole.
- Check that after assembly the piston can tilt freely on the connecting rod in both directions.
- Install both compression rings and the oil scraper ring as shown in Figure 87. Both compression rings can be installed upside down by mistake. To avoid mistakes, the letters "T" or "N" are marked on one side and these letters must be visible from the piston bottom (from above) after the ring is installed.
