3) Install piston and connecting rod assembly into cylin-
der bore.
Apply engine oil to pistons, rings, cylinder walls,
connecting rod bearings and crank pins.
Put guide hoses over connecting rod bolts as
shown. These guide hoses protect crankpin and
thread of rod bolt from damage during installa-
tion of connecting rod and piston assembly.
When installing piston and connecting rod
assembly into cylinder bore, point arrow mark on
each piston head to crankshaft pulley side.
Use piston ring compressor (Special tool) to
compress rings. Guide connecting rod into
place on the 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.
NOTE:
After installing piston and connecting rods,
double–check to be sure that the arrows on piston
crowns are all pointing to pulley (front) side.
Apply engine oil to crankpins.
4) Install connecting rod bearing cap.
When installing cap to rod, point arrow mark on cap to
crankshaft pulley side.
Tighten cap nuts to specification
After fitting all three big–end bearing caps, start tighten-
ing them uniformly, being sure to equalize tightness
between right and left on each cap. The sequence here
is similar to that for crankshaft bearing caps.
Tightening torque for big–end
caps
31–35 N–m
3.1–3.5 kg–m
22.5–25.0 lb–ft
