Assembly of pistons and connecting rods [Toyota Carina T170]

When assembling pistons and connecting rods, observe the following instructions:

The arrow on the piston crown (either stamped or on a new connecting rod labeled "VORN") should point toward the front of the engine.
The "FRONT" mark on the connecting rod should face the front of the engine. There is a boss at (2) on the 1.6L engine. On the 2.0L engine, the straight edge of the connecting rod should face forward.
The cylinder number indices (Fig. 22) on the connecting rods and bearing caps must match.
Check that after assembly the piston can freely tilt on the connecting rod in both directions.
Carefully insert the lower side part of the oil scraper ring, the expansion spring and the upper side part of the ring into the lower groove with your fingers. The position of the thermal clearances does not matter.
Using piston ring pliers, insert the piston rings into the grooves one by one (see Fig. 87) To avoid mixing up the compression rings, inspect their cross-section before installation. The second compression ring has an upward bevel on the outer side. In addition, the compression rings have markings and inscriptions that should be visible from the piston bottom after installation.
