Pistons, Piston Rings, Connecting Rods and Cylinders Removal and Installation
Removal
2)
Disconnect negative cable at battery.
3)
Drain engine oil.
4)
Drain coolant.
6)
Mark cylinder number on all pistons, connecting rods and connecting rod caps using silver pencil or quick drying paint.
7)
Remove rod bearing caps.
8)
Install guide hose (1) over threads of rod bolts.
This prevents damage to bearing journal and rod bolt threads when removing connecting rod.
9)
Decarbon top of cylinder bore before removing piston from cylinder.
10)
Push piston and connecting rod assembly out through the top of cylinder bore.
Installation
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)
Install guide hoses (1) over connecting rod bolts.
These guide hoses protect crank pin and threads of rod bolt from damage during installation of connecting rod and piston assembly.
3)
When installing piston and connecting rod assembly into cylinder bore, point front mark (1) on piston head to crankshaft pulley side.
A:
|
Crankshaft pulley side
|
B:
|
Flywheel side
|
4)
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.

5)
Install bearing cap (1):
Point arrow mark (2) on cap to crankshaft pulley side.
After applying engine oil to rod bolts and tighten cap nuts (3) gradually as follows.
a)
Tighten all cap nuts to 15 N·m (1.5 kgf-m, 11.0 lbf-ft).
b)
Retighten them to 45°
c)
Repeat Step b) once again.

15 N·m (1.5 kgf-m, 11.0 lbf-ft) and extra tightening 45° twice
6)
Reverse removal procedure for installation as previously outlined.
10)
Check to ensure that all removed parts are back in place. Reinstall any necessary parts which have not been reinstalled.
11)
Refill cooling system with coolant engine with engine oil and A/T with specified A/T fluid (vehicle with A/T).
12)
Connect negative cable at battery.
13)
Verify that there is no fuel leakage, coolant leakage, oil leakage, A/T fluid leakage (vehicle with A/T) and exhaust gas leakage at each connection.
