Piston, Piston Ring, Connecting Rod and Cylinder Removal and Installation
Precautions: General safety (00)
Removal
1)Remove engine assembly from vehicle. 
2)Remove cylinder head.
3)Mark cylinder numbers on all pistons, connecting rods and connecting rod caps using silver pencil or quick drying paint.
4)Remove connecting rod bearing caps.
5)Remove carbon deposits from top of cylinder bore before removing piston from cylinder.
6)Push piston and connecting rod assembly out from the top of cylinder bore.
7)Remove connecting rod bearings from connecting rod and connecting rod bearing cap, if necessary.
Installation
NOTICE:
The engine will seize up if it is operated when the parts listed below are not properly lubricated.
Lubricate all the friction surfaces of these parts with engine oil before installing them.
•Crankshaft pins
•Connecting rod bearings
•Pistons
•Piston rings
•Cylinder walls
•Connecting rod bearings
•Pistons
•Piston rings
•Cylinder walls
1)Apply engine oil to pistons, piston rings, cylinder walls, connecting rod bearings and crankshaft pins.
NOTICE:
If oil is present between the bearing’s outside surface and the connecting rod surface, the bearing could heat up to very high temperature, resulting in seizure.
Thoroughly wipe off any trace of oil that is present between the bearing’s outside surface and the connecting rod surface.
2)Install connecting rod bearing to connecting rod bearing cap and connecting rod as follows.
a)Fit tab (1) of connecting rod bearing to groove (2) of connecting rod and bearing cap.
b)Press bearing end (3) until it becomes flush with connecting rod or connecting rod bearing cap mating surface.
3)When installing piston and connecting rod assembly into cylinder bore, point front mark (1) on piston head to crankshaft pulley side (2).
4)Install piston and connecting rod assembly into cylinder bore. Use special tool to compress rings. Guide connecting rod into place on crankshaft.
Tap piston head to install piston into bore. Hold ring compressor firmly against cylinder block until all piston rings enter the cylinder bore.
Tap piston head to install piston into bore. Hold ring compressor firmly against cylinder block until all piston rings enter the cylinder bore.
5)Install bearing cap (1) as follows.
NOTICE:
Using connecting rod bolts that are deformed exceeding the service limit could lead to engine problems.
Before installing connecting rod bearing cap, check that connecting rod bolts are not deformed exceeding the service limit referring to “Connecting rod bolt deformation” under Piston Pin and Connecting Rod Inspection:M16A.
NOTE:
Tighten connecting rod bearing cap bolt (3) gradually.
a)Point front mark (2) on cap to crankshaft pulley side.
b)Apply engine oil to bolt thread and seat of connecting rod bolt.
c)Tighten all connecting rod bolts evenly and gradually to 15 N·m (1.5 kgf-m, 11.0 lbf-ft).
d)Retighten them 45°.
6)Install cylinder head.
7)Install engine assembly.
