Apply a continuous bead of liquid gasket with tube presser
[SST: WS39930000 ( — )] to rear oil seal retainer as
shown in the figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS".
10. Install piston to connecting rod.
a. Using snap ring pliers, install new snap ring to the groove of the piston rear side.
Insert it fully into groove to install.
b. Install piston to connecting rod.
Using industrial use drier or similar tool, heat piston until piston pin can be pushed in by hand without
excess force [approx. 60 to 70
C (140 to 158F)]. From the front to the rear, insert piston pin into piston
and connecting rod.
Assemble so that the front mark on the piston head and the oil
holes and the cylinder No. on connecting rod are positioned
as shown in the figure.
c. Using snap ring pliers, install new snap rings to the groove of the
piston front side.
Insert it fully into groove to install.
After installing, make sure that connecting rod moves
smoothly.
11. Using piston ring expander (commercial service tool), install pis-
ton rings.
CAUTION:
When installing piston rings, be careful not to damage
piston.
Be careful not to damage piston rings by expending them
excessively.
Position each ring with the gap as shown in the figure, refer-
ring to the piston front mark.
Install top ring and second ring with the stamped surface fac-
ing upward.
12. Install connecting rod bearings to connecting rod and connecting rod bearing cap.
Before installing connecting rod bearings, apply engine oil to the bearing surface (inside). Do not apply
engine oil to the back surface, but thoroughly clean it.

When installing, align the connecting rod bearing stopper pro-
trusion with the cutout of connecting rod and connecting rod
bearing cap to install.
Ensure the oil holes on connecting rod and that on the corre-
sponding bearing are aligned.
13. Install piston and connecting rod assembly to crankshaft.
Position the crankshaft pin corresponding to connecting rod to be installed onto the bottom dead center.
Apply engine oil sufficiently to the cylinder bore, piston and crankshaft pin journal.
Match the cylinder position with the cylinder No. on connecting rod to install.
Be sure that front mark on piston head is facing front of engine.
Using piston ring compressor [SST: EM03470000 (J8037)],
install piston with the front mark on the piston head facing the
front of engine.
CAUTION:
Be careful not to damage cylinder wall and crankshaft pin,
resulting from an interference of the connecting rod big
end.
14. Install connecting rod bearing cap.
Match the stamped cylinder number marks on connecting rod
with those on cap to install.
15. Tighten connecting rod nuts as follows:
a. Apply new engine oil to the threads and seats of connecting rod bolts and nuts.
b. Tighten connecting rod nuts.
c. Then tighten all connecting rod nuts 60 degrees clockwise.
(Angle tightening)
CAUTION:
Use angle wrench (SST) to check tightening angle. Do not
make judgment by visual inspection.
After tightening connecting rod nuts, make sure that crank-
shaft rotates smoothly.
Check the connecting rod side clearance. Refer to EM-266,
"CONNECTING ROD SIDE CLEARANCE" .

When replacing piston and piston pin assembly, refer to EM-260, "HOW TO SELECT PISTON" .
NOTE:
Piston is available together with piston pin as assembly.
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.)
PISTON RING SIDE CLEARANCE
Measure the side clearance of piston ring and piston ring groove
with feeler gauge.
If the measured value exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
replace piston also.
PISTON RING END GAP
Make sure that the cylinder bore inner diameter is within the
specification. Refer to EM-270, "
Cylinder Bore Inner Diameter" .
Lubricate with new engine oil to piston and piston ring, and then
insert piston ring until middle of cylinder with piston, and mea-
sure the piston ring end gap with feeler gauge.
If the measured value exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
re-bore cylinder and use oversize piston and piston rings.Standard:
Top ring : 0.045 - 0.080 mm (0.0018 - 0.0031 in)

When installing rubber bushings, the final tightening must be carried out under unladen conditions with
tires on ground. Oil might shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
–Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
After servicing suspension parts, be sure to check wheel alignment.
Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-
oiled, tighten as they are.

FRONT SUSPENSION ASSEMBLYPFP:54010
On-Vehicle Inspection and ServiceNES000IA
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION OF LOWER BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Place an iron bar or similar tool between transverse link and steering knuckle.
3. Measure axial end play by prying it up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.
SHOCK ABSORBER INSPECTION
Check for oil leakage, damage and breakage of installation positions.
Wheel Alignment InspectionNES000IB
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
PRELIMINARY CHECK
Check the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to WT-6, "
ROAD WHEEL" .
3. Wheel bearing axial end play. Refer to FAX-5, "
WHEEL BEARING INSPECTION" .
4. Transverse link ball joint axial end play. Refer to FSU-14, "
INSPECTION AFTER REMOVAL" .
5. Shock absorber operation.
6. Each mounting part of axle and suspension for looseness and deformation.
7. Each of suspension member, shock absorber, upper link and transverse link for cracks, deformation and
other damage.
8. Vehicle height (posture).
GENERAL INFORMATION AND RECOMMENDATIONS
A four-wheel thrust alignment should be performed.
–This type of alignment is recommended for any NISSAN/INFINITI vehicle.
–The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel is
centered.
–The alignment rack itself should be capable of accepting any NISSAN/INFINITI vehicle.
–The rack should be checked to ensure that it is level.
Make sure the machine is properly calibrated.
–Your alignment equipment should be regularly calibrated in order to give correct information.
–Check with the manufacturer of your specific equipment for their recommended Service/Calibration
Schedule.Axial end play : 0 mm (0 in)
