Caution! Always replace the four pistons together with the pins. If one cylinder needs to be ground, all pistons together with the pins should be ground and replaced. The same diameter also means that they have the same weight, which in turn is a condition for proper engine balancing.
1. Compress the piston rings with a mandrel.

2. Insert the piston with the connecting rod into the cylinder, making sure that the arrow on the bottom of the piston points towards the valve timing drive.
3. Install the connecting rod cap and tighten the bolts to the specified torque.
4. Install the oil pan and cylinder head.
5. Fill the engine with engine oil and coolant into the cooling system.
