DESCRIPTION
 The identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.
 For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the
measurement with the values of each selection table.
 For details of the measurement method of each part, the reuse standards and the selection method of the
selective fitting parts, follow the procedures.
HOW TO SELECT PISTON
When New Cylinder Block is Used
 Check the cylinder bore grade on rear left side of cylinder block (L),
and select piston of the same grade.
 If there is a correction stamp mark on the cylinder block, use it as a
correct reference.
When Cylinder Block is Reused
1. Measure the cylinder bore inner diameter. Refer to EM-219, "Inspection After Disassembly".
2. Determine the bore grade by comparing the measurement with the values under the cylinder bore inner
diameter of the “Piston Selection Table”.

Precaution for Disconnecting Fuel PipingINFOID:0000000001381451
 Before starting work, make sure no fire or spark producing items are in the work area.
 Release fuel pressure before disassembly.
 After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000001381452
 When instructed to use special service tools, use the specified tools. Always be careful to work safely, avoid
forceful or uninstructed operations.
 Exercise maximum care to avoid damage to mating or sliding surfaces.
 Cover openings of engine system with tape or the equivalent, if necessary, to seal out foreign materials.
 Mark and arrange disassembly parts in an organized way for easy troubleshooting and re-assembly.
 When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, do exactly as specified.
Precaution for Inspection, Repair and ReplacementINFOID:0000000001381453
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and InstallationINFOID:0000000001381454
 Use torque wrench to tighten bolts or nuts to specified value.
 When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified,
do exactly same as specified.
 Replace with new gasket, packing, oil seal or O-ring.
 Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction
and blockage.
 Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assemble, spread the oil on sliding surfaces well.
 Release air within route when refilling after draining coolant.
 Before starting engine, apply fuel pressure to fuel lines with turning ignition switch ON (with engine stopped).
Then make sure that there are no leaks at fuel line connections.
 After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for
leakage.

Precaution for Liquid GasketINFOID:0000000001381456
REMOVAL OF LIQUID GASKET
 After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter and remove the liquid gasket.
CAUTION:
Be careful not to damage the mating surfaces.
 In areas where the cutter is difficult to use, use a plastic hammer to
lightly tap the liquid gasket applied area.
CAUTION:
If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating sur-
faces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the
gasket application surface and the mating surface.
 Remove the liquid gasket completely from the groove of the
gasket application surface, mounting bolts and bolt holes.
2. Wipe the gasket application surface and the mating surface with
white gasoline (lighting and heating use) to remove adhering
moisture, grease and foreign materials.
3. Attach the liquid gasket to the tube presser.
Use Genuine Liquid Gasket or equivalent.
4. Apply the liquid gasket without breaks to the specified location
with the specified dimensions.
 If there is a groove for the liquid gasket application, apply the
gasket to the groove.
 As for the bolt holes, normally apply the gasket inside the
holes. If specified, it should be applied outside the holes. Make
sure to read the instruction in this manual.
 Within five minutes of gasket application, install the mating
component.
 If the liquid gasket protrudes, wipe it off immediately.
 Do not retighten after the installation.
 After 30 minutes or more have passed from the installation, fill
the engine oil and coolant.
CAUTION:
If there are instructions in this manual, observe them.

CLEANLINESS
CLEANLINESS INSTRUCTIONS WHICH MUST BE FOLLOWED WHEN WORKING ON THE HIGH PRES-
SURE DIRECT INJECTION SYSTEM
Risks relating to contamination
PBIC0275E
PBIC0003E
EMA0622D
SEM159F

EM-254
< PRECAUTION >[K9K]
PRECAUTIONS
The system is very sensitive to contamination. The risks caused by the introduction of contamination are: Damage or destruction of the high pressure injection system and the engine,
 Seizing or leaking of a component.
All After-Sales operations must be performed under very clean conditions. This means that no impurities (par-
ticles a few microns in size) get into the system during dismantling or into the circuits via the fuel unions.
The cleanliness principle must be applied from the filter to the injectors.
WHAT ARE THE SOURCES OF CONTAMINATION?
Contamination is caused by:
 Metal or plastic chips,
 Paint,
Fibres:
- Boxes,
- Brushes,
- Paper,
- Clothing,
- Cloths,
 Foreign bodies such as hair,
 Ambient air,
Etc.
IMPORTANT: It is not possible to clean the engine using a high pressure washer because of the risk of dam-
aging connections. In addition, moisture may collect in the connectors and create electrical connection mal-
functions.
INSTRUCTIONS TO BE FOLLOWED BEFORE ANY WORK IS CARRIED OUT ON THE INJECTION SYS-
TEM
 Ensure that you have the plugs for the unions to be opened (bag of plugs sold at the Parts Stores - Nissan
part No.: 16609 00Q0B, Renault part No.: 77 01 476 857). Plugs are to be used once only. After use, they
must be thrown away (once used they are soiled and cleaning is not sufficient to make them reusable).
Unused plugs must be thrown away.
 Ensure that you have hermetically resealable plastic bags for storing removed parts. Stored parts will there-
fore be less subject to the risk of impurities. The bags must be used only once, and after use they must be
thrown away.
 Lint-free towelettes to be used for high pressure supply pump related service purpose. The use of a normal
cloth or paper for cleaning purposes is forbidden. These are not lint-free and may contaminate the fuel circuit
of the system. Each lint-free cloth should only be used once.
INSTRUCTIONS TO BE FOLLOWED BEFORE OPENING THE FUEL CIRCUIT
 For each operation, use new thinner (used thinner contains impurities). Pour it into a clean receptacle.
 For each operation, use a clean brush which is in good condition (the brush must not shed its bristles).
 Use a brush and thinners to clean the connections to be opened.
 Blow compressed air over the cleaned parts (tools, cleaned the same way as the parts, connections and
injection system zone). Check that no bristles remain adhered.
 Wash your hands before and during the operation if necessary.
 When wearing leather protective gloves, cover these with latex gloves.
INSTRUCTIONS TO BE FOLLOWED DURING THE OPERATION
 As soon as the circuit is open, all openings must be plugged to prevent impurities from entering the system.
The plugs to be used are available from the Parts Stores - Nissan part No.: 16609 00Q0B, Renault part No.:
77 01 476 857. They must not, under any circumstances, be reused.
 Close the hermetically sealed bag, even if it has to be reopened shortly afterwards. Ambient air carries con-
tamination.
 All components of the injection system that are removed must be stored in a hermetically sealed plastic bag
once the plugs have been inserted.
 The use of a brush, thinner, bellows, sponge or normal cloth is strictly forbidden once the circuit has been
opened. These items are likely to allow impurities to enter the system.
 A new component replacing an old one must not be removed from its packaging until it is to be fitted to the
vehicle.
