d. Hoist up engine and install it on the engine stand (SST).
+Another method is to set engine sub-attachment and engine
attachment on engine stand beforehand, and then, install
engine.
3. Drain engine oil and coolant from engine.
4. Remove the following and the associated parts:
+Exhaust manifold
+Turbocharger assembly
+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
+Thermostat, water pipes
+Oil cooler
+Auxiliary component brackets
5. Remove fuel injection pump bracket.

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-144, ªCONNECT-

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.
