WARNING:
IPosition vehicle on a flat and solid surface.
IPlace chocks at front and back of rear wheels.
IDo not remove engine until exhaust system has com-
pletely cooled off, otherwise, you may burn yourself
and/or fire may break out in fuel line.
IBefore disconnecting fuel hose, release pressure.
Refer to EC section (ªFuel Pressure Releaseº, ªBASIC
SERVICE PROCEDUREº).
IBe sure to lift engine and transaxle in a safe manner.
IFor engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATALOG.
CAUTION:
IWhen lifting engine, be sure to clear surrounding parts.
Use special care near accelerator wire casing, brake lines
and brake master cylinder.
IWhen lifting the engine, always use engine slingers in a
safe manner.
IWhen removing drive shaft, be careful not to damage
grease seal of transaxle.
IBefore separating engine and transaxle, remove crank-
shaft position sensor (POS) from the cylinder block
assembly.
IAlways be extra careful not to damage edge of crankshaft
position sensor (POS), or signal plate teeth.
Engine cannot be removed separately from transaxle. Remove
engine with transaxle as an assembly.
REMOVALNCEM0022S011. Drain coolant from radiator and cylinder block. Refer to (LC)
section (ªChanging Engine Coolantº, ªENGINE MAINTE-
NANCEº).

Removal and InstallationNCEM0024CAUTION:
IWhen installing sliding parts such as bearings and
pistons, apply engine oil on the sliding surfaces.
IPlace removed parts, such as bearings and bearing caps,
in their proper order and direction.
IWhen installing connecting rod nuts and main bearing cap
bolts, apply new engine oil to threads and seating sur-
faces.
IDo not allow any magnetic materials to contact the signal
plate teeth of flywheel or drive plate, and rear plate.
IRemove the crankshaft position sensor (POS).
IBe careful not to damage sensor edges and single plate
teeth.
DisassemblyNCEM0025PISTON AND CRANKSHAFTNCEM0025S011. Place engine on a work stand.
2. Drain coolant and oil.
3. Remove timing chain.
Refer to EM-20.
4. Remove pistons with connecting rod.
IWhen disassembling piston and connecting rod, remove snap
ring first. Then heat piston to 60 to 70ÉC (140 to 158ÉF) or use
piston pin press stand at room temperature.
CAUTION:
IWhen piston rings are not replaced, make sure that piston
rings are mounted in their original positions.
IWhen replacing piston rings, if there is no punch mark,
install with either side up.
5. Loosen main bearing caps in numerical order as shown in fig-
ure.
6. Remove bearing caps, main bearings and crankshaft.
IBefore removing bearing caps, measure crankshaft end
play. Refer to EM-61.
IBolts should be loosened in two or three steps.
