1) Apply engine oil to pistons, rings, cylinder walls, connecting rod bearings and crank pins.

NOTE: Do not apply oil between connecting rod and bearing or between bearing cap and bearing.

2) When installing piston and connecting rod assembly into cylinder bore, point mark (1) on piston head to crankshaft pulley side (2).





3) Install piston and connecting rod assembly into cylinder bore. Use special tool (Piston ring compressor) to compress rings. Guide connecting rod into place on crankshaft.
Using a hammer handle, tap piston head to install piston into bore. Hold ring compressor firmly against cylinder block until all piston rings have entered cylinder bore.

4) Install connecting rod bearing cap (1) as follows.

NOTE: If connecting rod bolt is reused, mark sure to check connecting rod bolt for deformation, referring to "Connecting Rod Bolt Deformation (Plastic Deformation Tightening Bolt)" under Crank Pins and Connecting Rod Bearings Inspection.

a) Point arrow mark (2) on cap to crankshaft pulley side.
b) Apply engine oil to new connecting rod bolts (3).
c) Tighten all connecting rod bolts to 15 Nm (1.5 kgf-m, 11.0 ft. lbs.).
d) Retighten them by turning through 45°
e) Repeat step d) once again.
