of the crankshaft using pilot bushing puller (SST).

It is possible to remove pilot converter without hoisting engine
with engine stand.
ASSEMBLY
1. Fully air-blow engine coolant and engine oil passages in cylinder block, cylinder bore and crankcase to remove any foreign material.
CAUTION:
Use a goggles to protect your eye.
2. Install each plug to the cylinder block. (Only screwed-type plugs are shown in the figure.)

Apply sealant to the thread of each plug “A” and “D”.
Use Genuine High Strength Locking Sealant or equiva-
lent. Refer to GI-48, "
RECOMMENDED CHEMICAL PROD-
UCTS AND SEALANTS".

Apply sealant to the thread of each plug “B” and “C”.
Use Anaerobic Liquid Gasket or equivalent. Refer to GI-
48, "RECOMMENDED CHEMICAL PRODUCTS AND SEAL-
ANTS".

Replace copper washers with new ones.

Tighten each plug as specified below.
3. Install main bearings and thrust bearings as follows:
a. Remove dust, dirt and oil on the bearing mating surfaces of cylinder block and main bearing caps.
b. Install thrust bearings to the both sides of the No. 3 journal hous- ing on cylinder block and main bearing cap.

Install thrust bearings with the oil groove facing the crankshaft
arm (outside).

Install thrust bearing with a protrusion on one end on cylinder
block, and thrust bearing with a protrusion at center on main
bearing cap. Align each protrusion with mating notch.

Piston Pin Outer Diameter
Measure the outer diameter of piston pin with micrometer.
Connecting Rod Bushing Oil Clearance
(Connecting rod bushing oil clearance) = (Connecting rod bushing inner diameter) – (Piston pin outer diame-
ter)

If the calculated value exceeds the limit, replace connecting rod assembly and/or piston and piston pin
assembly.

If replacing piston and piston pin assembly, refer to EM-259, "HOW TO SELECT PISTON" .

If replacing connecting rod assembly, refer to EM-272, "CON-
NECTING ROD BEARING OIL CLEARANCE" to select the con-
necting rod bearing.

PRECAUTIONS
Revision: 2006 July 2007 FX35/FX45
PRECAUTIONSPFP:00001
CautionNES000FK

When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on ground. Oil will 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.

Caulking nuts are not reusable. Always use new ones when installing. Since new caulking nuts are pre-
oiled, tighten as they are.

Avoid burden to front cross bar.

FRONT SUSPENSION ASSEMBLY
Revision: 2006 July 2007 FX35/FX45
FRONT SUSPENSION ASSEMBLYPFP:54010
On-Vehicle Inspection and ServiceNES000I3
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION 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.
STRUT INSPECTION

Check strut for oil leakage, damage and replace if there are. Refer to FSU-11, "COIL SPRING AND
STRUT" .
Wheel Alignment InspectionNES000I4
DESCRIPTION

Measure wheel alignment under unladen conditions.
NOTE:
Unladen conditions mean that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are designated positions.
PRELIMINARY CHECK

Check tires for improper air pressure and wear.

Check road wheels for runout.

Check wheel bearing axial end play.

Check ball joint axial end play of compression rod, upper link, and steering knuckle

Check shock absorber operation.

Check each mounting part of axle and suspension for looseness and deformation.

Check each link, rod and member for cracks, deformation and other damage.

Check vehicle 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)
