INSULATOR (Light foam block)
80845-71L00: 30 mm (1.18 in) thick, 30 × 50 mm (1.18 × 1.97 in)
FELT CLOTHTAPE
Used to insulate where movement does not occur. Ideal for instrument panel applications.
68370-4B000: 15 × 25 mm (0.59 × 0.98 in) pad/68239-13E00: 5 mm (0.20 in) wide tape roll The following
materials, not found in the kit, can also be used to repair squeaks and rattles.
UHMW(TEFLON) TAPE
Insulates where slight movement is present. Ideal for instrument panel applications.
SILICONE GREASE
Used in place of UHMW tape that will be visible or not fit.
Note: Will only last a few months.
SILICONE SPRAY
Use when grease cannot be applied.
DUCT TAPE
Use to eliminate movement.
CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
Generic Squeak and Rattle TroubleshootingAIS00376
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. The cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by apply-
ing felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate wiring har-
ness.
CAUTION:
Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will
not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks from
the Nissan Squeak and Rattle Kit (J-43980) to repair the noise.

Undersize Bearings Usage Guide

When the specified oil clearance is not obtained with standard size connecting rod bearings, use under-
size (US) bearings.

When using undersize bearing, measure the bearing inner diameter with bearing installed, and grind
crankshaft pin so that the oil clearance satisfies the standard.
CAUTION:
In grinding crankshaft pin to use undersize bearings, keep the
fillet R [1.5 mm (0.059 in)].

HOW TO SELECT MAIN BEARING
When New Cylinder Block and Crankshaft Are Used
1. “Main Bearing Selection Table” rows correspond to bearing
housing grade on rear left side of cylinder block.
2. Apply journal diameter grade stamped on crankshaft front side
to column in “Main Bearing Selection Table”.
3. Find sign (main bearing grade) at crossing of row and column in
“Main Bearing Selection Table”.
When Cylinder Block and Crankshaft Are Reused
1. Measure inner diameter of cylinder block main bearing housing and outer diameter of crankshaft journal.
2. Find measured dimension in “Cylinder block bearing housing inner diameter” row of “Main Bearing Selec-
tion Table”.
3. Find the measured dimension in “Crankshaft main journal diameter” column in the following selection
table.
4. Select main bearing grade at the point where selected row and column meet in following selection table.

points in 6 directions.

If out of the distortion limit, replace cylinder block.
MAIN BEARING HOUSING INNER DIAMETER

Install main bearing caps and main bearing beam with main
bearings removed, and tighten mounting bolts to the specified
torque. Refer to EM-126, "
ASSEMBLY" for the tightening proce-
dure.

Using a bore gauge, measure the inner diameter of the main
bearing housing.

If out of the standard, replace cylinder block and main bearing
caps as assembly.
NOTE:
Cylinder block cannot be replaced as single part, because it is
machined together with main bearing caps.
PISTON TO CYLINDER BORE CLEARANCE
Cylinder Bore Inner Diameter

Using a bore gauge, measure cylinder bore for wear, out-of-
round and taper at 6 different points on each cylinder. (“X” and
“Y” directions at “A”, “B” and “C”) (“Y” is in longitudinal direction
of engine)

If the measured value exceeds the limit, or if there are scratches
and/or seizure on the cylinder inner wall, hone or re-bore the
inner wall.

An oversize piston is provided. When using an oversize piston,
re-bore cylinder so that the clearance of the piston-to-cylinder
bore satisfies the standard.
CAUTION:
When using oversize piston, use it for all cylinders with
oversize piston rings.

When using an oversize piston, use it for all cylinders with over-
size piston rings.Limit : 0.10 mm (0.0039 in)

If clearance cannot be adjusted within the standard, grind crankshaft pin and use undersized bearing.
Refer to EM-132, "
HOW TO SELECT CONNECTING ROD BEARING" .
Method of Using Plastigage

Remove engine oil and dust on crankshaft pin and the surfaces
of each bearing completely.

Cut a plastigage slightly shorter than bearing width, and place it
in crankshaft axial direction, avoiding oil holes.

Install connecting rod bearings to connecting rod and connect-
ing rod bearing cap, and tighten connecting rod bolts to the
specified torque. Refer to EM-126, "
ASSEMBLY" for the tighten-
ing procedure.
CAUTION:
Never rotate crankshaft.

Remove connecting rod cap and bearings, and using the scale
on the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is same as that described in the “Method by
Calculation”.
MAIN BEARING OIL CLEARANCE
Method by Calculation

Install main bearings to cylinder block and main bearing cap.
Measure the main bearing inner diameter with bearing cap bolt
tightened with main bearing beam to the specified torque. Refer
to EM-126, "
ASSEMBLY" for the tightening procedure.
(Oil clearance) = (Main bearing inner diameter) – (Crankshaft main
journal diameter)

If the measured value exceeds the limit, select main bearings
referring to the main bearing inner diameter and crankshaft jour-
nal outer diameter, so that the oil clearance satisfies the standard. Refer to EM-133, "
HOW TO SELECT
MAIN BEARING" .
Method of Using Plastigage

Remove engine oil and dust on crankshaft journal and the sur-
faces of each bearing completely.

Cut a plastigage slightly shorter than bearing width, and place it
in crankshaft axial direction, avoiding oil holes.

Install main bearing to cylinder block and main bearing cap, and
tighten main bearing bolts with main bearing beam to the speci-
fied torque. Refer to EM-126, "
ASSEMBLY" for the tightening
procedure.
CAUTION:
Never rotate crankshaft.

Remove bearing cap and bearings, and using the scale on the
plastigage bag, measure the plastigage width.

Check drive plate and signal plate for deformation or damage.
CAUTION:

Do not disassemble drive plate.

Never place drive plate with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.

If anything is found, replace drive plate.
OIL JET

Check nozzle for deformation and damage.

Blow compressed air from nozzle, and check for clogs.

If it is not satisfied, clean or replace oil jet.
OIL JET RELIEF VALVE

Using a clean plastic stick, press check valve in oil jet relief
valve. Make sure that valve moves smoothly with proper reac-
tion force.

If it is not satisfied, replace oil jet relief valve.

Piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts, no
piston pin grades can be selected. (Only “0” grade is available.)

No second grade mark is available on piston.
HOW TO SELECT CONNECTING ROD BEARING
When New Connecting Rod and Crankshaft Are Used:
Check pin diameter grade (“0”, “1” or “2”) on front of crankshaft, and
select connecting rod bearing of the same grade.
NOTE:
There is no grading for connecting rod big end diameter.
When Crankshaft and Connecting Rod Are Reused:
1. Measure the connecting rod big end diameter. Refer to EM-258, "CONNECTING ROD BIG END DIAME-
TER" .
2. Make sure that the connecting rod big end diameter is within the standard value.
3. Measure the crankshaft pin journal diameter. Refer to EM-262, "
CRANKSHAFT PIN JOURNAL DIAME-
