WARNING:
+Position vehicle on a flat and solid surface.
+Place chocks at front and back of rear wheels.
+Do 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.
+Before disconnecting fuel hose, release pressure.
Refer to EC-40, ªFuel Pressure Releaseº.
+Be sure to lift engine and transaxle in a safe manner.
+For engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATALOG.
CAUTION:
+When lifting engine, be sure to clear surrounding parts.
Use special care near accelerator wire casing, brake lines
and brake master cylinder.
+When lifting the engine, always use engine slingers in a
safe manner.
+When removing drive shaft, be careful not to damage
grease seal of transaxle.
+Before separating engine and transaxle, remove crank-
shaft position sensor (POS) from the cylinder block
assembly.
+Always 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.
REMOVALNJEM0022S011. Drain coolant from radiator and cylinder block. Refer to LC-18,
ªChanging Engine Coolantº.
2. Remove coolant reservoir tank and bracket.
3. Drain engine oil.
4. Remove battery and battery tray.
5. Remove air cleaner and air duct.
6. Remove drive belts.
7. Remove alternator and air conditioner compressor from

Removal and InstallationNJEM0024CAUTION:
+When installing sliding parts such as bearings and
pistons, apply engine oil on the sliding surfaces.
+Place removed parts, such as bearings and bearing caps,
in their proper order and direction.
+When installing connecting rod nuts and main bearing cap
bolts, apply new engine oil to threads and seating sur-
faces.
+Do not allow any magnetic materials to contact the signal
plate teeth of flywheel or drive plate, and rear plate.
+Remove the crankshaft position sensor (POS).
+Be careful not to damage sensor edges and single plate
teeth.

DisassemblyNJEM0025PISTON AND CRANKSHAFTNJEM0025S011. Place engine on a work stand.
2. Drain coolant and oil.
3. Remove timing chain.
Refer to EM-24.
SEM877B
4. Remove pistons with connecting rod.
+When 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:
+When piston rings are not replaced, make sure that piston
rings are mounted in their original positions.
+When 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.
+Before removing bearing caps, measure crankshaft end
play. Refer to EM-63.
+Bolts should be loosened in two or three steps.

3. Install crankshaft and main bearing caps and tighten bolts to
the specified torque.
+Apply new engine oil to the bolt thread and seat surface.
+Prior to tightening bearing cap bolts, shift crankshaft back
and forth to properly seat the bearing caps.
+Tighten bearing cap bolts gradually in two or three stages.
Start with center bearing and move outward as shown in
figure.
+After securing bearing cap bolts, make sure crankshaft
turns smoothly by hand.

4. Measure crankshaft end play.
Crankshaft end play:
Standard
0.060 - 0.220 mm (0.0024 - 0.0087 in)
Limit
0.3 mm (0.012 in)
If beyond the limit, replace thrust bearing with new ones.

5. Install connecting rod bearings in connecting rods and con-
necting rod caps.
+Confirm that correct bearings are used. Refer to EM-60.
+Install bearings so that oil hole in connecting rod aligns
with oil hole of bearing.
+Apply new engine oil to bolt threads and bearing surfaces.
SEM942F
6. Install pistons with connecting rods.
a. Install them into corresponding cylinders with Tool.
+Make sure connecting rod does not scratch cylinder wall.
+Make sure connecting rod bolts do not scratch crankshaft
pin journals.
+Arrange so that front mark on piston head faces engine.
+Apply new engine oil to piston rings and sliding surface
of piston.
SEM943F
b. Install connecting rod caps.
Apply new engine oil to bolt threads and nut seating surfaces.
Tighten connecting rod cap nuts in the following procedure:
+Tighten to 13.72 to 15.68 N´m (1.399 to 1.599 kg-m, 10.120
to 11.566 ft-lb).
+Turn nuts to 35É to 40É degrees clockwise with an angle
wrench. If an angle wrench is not available, tighten nuts to
23 to 28 N´m (2.3 to 2.9 kg-m, 17 to 21 ft-lb).

Parts Requiring Angular TighteningNJEM0047+Use an angle wrench for the final tightening of the following
engine parts:
a) Cylinder head bolts
b) Main bearing cap bolts
c) Connecting rod cap nuts
d) Crankshaft pulley bolt
+Do not use a torque value for final tightening.
+The torque value for these parts are for a preliminary step.
+Ensure thread and seat surfaces are clean and coated with
engine oil.

Liquid Gasket Application ProcedureNJEM00481.Use a scraper to remove all traces of old liquid gasket
from mating surfaces and grooves. Also, completely clean
any oil from these areas.
2.Apply a continuous bead of liquid gasket to mating sur-
faces. (Use Genuine Liquid Gasket or equivalent.)
