4. Remove the following and the associated parts:
+Exhaust manifold
+Turbocharger assembly (For Europe)
+Injection tube
+Intake manifold
+Oil pan (upper and lower)
+Secondary timing chain
+Fuel injection pump
+Primary timing chain
+Rocker cover
+High pressure injection nozzle assembly
+Camshaft
+Cylinder head

6. If the replacement of pilot bushing is necessary, remove it with
pilot bushing puller (SST).
7. Remove rear oil seal retainer.
+Insert a flat-bladed screwdriver between main bearing cap and
rear oil seal retainer to remove retainer.
8. Remove rear oil seal from rear oil seal retainer.
+Punch out with a flat-bladed screwdriver.
+Be careful not to damage rear oil seal retainer.

9. Remove piston and connecting rod assembly.
a. Set crankshaft pin of the removal location at a position close
to BDC.
b. Remove connecting rod cap.
c. Push piston and connecting rod assembly toward cylinder
head using a hammer handle.
+Before removing piston and connecting rod assembly, check
connecting rod side clearance. Refer to EM-143, ªCONNECT-
ING ROD SIDE CLEARANCEº.

OIL JET RELIEF VALVENJEM0073S20Using a clean resin rod, press down on the check valve inside relief
valve. Check for appropriate bounce/repulsion and smooth
operation.
AssemblyNJEM0074PISTONNJEM0074S011. With using snap ring pliers, install snap rings to grooves at the
rear side of the piston.
+Install securely to fully fit into the groove.
2. Install piston to the connecting rod.
+Heat the piston with an industrial drier to 60 to 70ÉC (140 to
158ÉF) so that the piston pin can be easily inserted by finger.
Then, insert the piston pin from the front of the piston into the
piston and into the connecting rod.
JEM227G
+Assemble so that the front mark on the piston top surface and
cylinder No. stamped on connecting rod are positioned as
shown in the figure.
3. Install snap ring on piston front.
+Refer to step 1. above for notes for installation.
+After installing, check that the connecting rod moves smoothly.
4. Install piston rings using piston ring expander (Commercial
Service Tool).
+Be extremely careful to avoid any damage to the piston.
JEM228G
+Install top ring and second ring with the punched surface fac-
ing upward.
Identification mark:
Top ring AE
Second ring AE2
+Install rings so that three closed gap position 120É apart one
another.
+Closed gaps do not need to face in a specific directions, as
long as each are positioned 120É apart.
JEM223G
CRANKSHAFTNJEM0074S021. Blow air sufficiently into the coolant passage, oil passage in the
cylinder block, inside of crankshaft case, and inside of cylinder
bores to remove any foreign materials.
2. Install oil jet relief valves.
3. Install oil jets.

Precautions
LIQUID GASKET APPLICATION PROCEDURENJLC00011. 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 surfaces.
(Use Genuine Liquid Gasket or equivalent.)
+For oil pan, be sure liquid gasket diameter is 3.5 to 4.5 mm
(0.138 to 0.177 in).
+For areas except oil pan, be sure liquid gasket diameter is 2.0
to 3.0 mm (0.079 to 0.118 in).
3. Apply liquid gasket around the inner side of bolt holes (unless
otherwise specified).
4. Assembly should be done within 5 minutes after coating.
5. Wait at least 30 minutes before refilling engine oil and engine
coolant.
