Cylinders Removal and Installation
S5JB0A1416030
Removal
1) Remove engine assembly from vehicle referring to
“Engine Assembly Removal and Installation: For
M16A Engine with VVT”.
2) Remove cylinder head referring to “Valves and
Cylinder Head Removal and Installation: For M16A
Engine with VVT”.
3) Mark cylinder number on all pistons, connecting rods
and connecting rod caps using silver pencil or quick
drying paint.
4) Remove rod bearing caps.
5) Install guide hose (1) over threads of rod bolts.
This prevents damage to bearing journal and rod bolt
threads when removing connecting rod.
6) Decarbonize top of cylinder bore before removing
piston from cylinder.
7) Push piston and connecting rod assembly out
through the top of cylinder bore.
[A]: 1) Tighten all nuts to 15 N
⋅
m (1.5 kgf-m).
2) Then retighten all nuts by turning through 45
°
.
3) Repeat Step 2) again.
7. Connecting rod bearing
1. Top ring
8. Piston pin
2. 2nd ring
9. Piston pin circlip
3. Oil ring
10. Bearing cap nut
4. Piston
: Tightening torque
5. Connecting rod
: See “A”
: Apply engine oil to sliding surface of each part.
6. Connecting rod bearing cap
: See “B”
: Do not reuse.
“A”: Apply engine oil to sliding surface except inner surface of big end, and rod bolts.
Check rod bolt, plastic deformation tightening bolt, for deformation referring to “Connecting rod bolt deformation (Plastic deformation tightening bolt) under
“Piston Pins and Connecting Rods Inspection: For M16A Engine with VVT”, if it is reused
“B”: Point arrow mark on cap to crankshaft pulley side.
