Install the oil ring expander and oil ring to the piston. Then, install No.2 piston ring and No.1 piston ring, in that order. Make sure that the ring side, on which manufacturer and size marks are stamped, faces tothe piston crown.
Position ends of piston and oil (side rail, spacer) rings as illustrated.
Insert the piston and connecting rod assembly from above the top of cylinder. Ensure that the front mark on piston crown and that (ID mark) on the connecting rod face toward the front of engine (to the crank pulleyside).
Clamp firm the piston rings with the ring band and install the piston assembly into cylinder. Do not strike it hard into the piston, as broken pistonring or damaged crank pin could result.
Tighten the connecting rod cap bolts.

Connecting rod cap bolts : |
25 Nm (250 kg·cm, 18·4 lb·ft) + 90° |
Re-use of the bolt must be limited to 3 times.
Make sure the clearance of connecting rod big end side.
