A widely use engine stand can be used.
CAUTION:
Use engine stand that has a load capacity [approximately
220 kg (441 lb) or more] large enough for supporting the
engine weight.
NOTE:
This example is engine stand for holding at transaxle mount-
ing side with drive plate removed.
5. Drain engine oil. Refer to LU-21, "
Changing Engine Oil" .
6. Drain engine coolant by removing water drain plugs from cylin-
der block both sides at “A” and “D” and cylinder block front side
at “B” as shown in the figure.
NOTE:
Water drain plug at the right bank side for VQ35DE is also used
as a connector of water pipe for oil cooler. Refer to LU-23, "
OIL
COOLER (VQ35DE)" .
7. Remove drive plate. Fix crankshaft pulley with pulley holder [SST: KV10109300], and remove mounting
bolts.

Loosen mounting bolts in diagonal order.
CAUTION:

Do not disassemble drive plate.

Do not 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.
8. Remove cylinder head. Refer to EM-210, "
CYLINDER HEAD" .
9. Remove knock sensor.
CAUTION:
Carefully handle sensor avoiding shocks.

17. Remove main bearing beam. (VQ35DE)
18. Remove main bearing caps.

Using main bearing cap bolts, remove main bearing cap while
shaking it back-and-forth.
19. Remove crankshaft.
20. Remove main bearings and thrust bearings from cylinder block and main bearing caps.
CAUTION:
Identify installation positions, and store them without mixing them up.
21. Remove oil jet. (VQ35DE)
ASSEMBLY
NOTE:
Show VQ35DE (with main bearing beam, connecting rod bearing cap is tighten by bolts) as an example unless
the figure includes specification.
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.

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-240, "HOW TO SELECT PISTON" .

If replacing connecting rod assembly, refer to EM-251, "CON-
NECTING ROD BEARING OIL CLEARANCE" to select the
connecting rod bearing.
Factory installed parts grading:

Service parts apply only to grade “0”.

CYLINDER BLOCK DISTORTION

Using scraper, remove gasket on the cylinder block surface, and also remove engine oil, scale, carbon, or
other contamination.
CAUTION:
Be careful not to allow gasket flakes to enter engine oil or engine coolant passages.Standard : 21.989 - 22.001 mm (0.8657 - 0.8662 in)

PRECAUTIONS

PRECAUTIONSPFP:00001
CautionBES0003G

When installing rubber bushings, final tightening must be performed 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. A spare tire, a jack, hand tools
and mats are in designated positions.

After servicing suspension parts, be sure to check wheel alignment.

Self-lock nut are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-
oiled, tighten as they are.

On-Vehicle Inspection BES0003K
Make sure that the mounting conditions (looseness, back lash) of each component and component status
(wear, damage) are normal.
INSPECTION OF TRANSVERSE LINK BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Measure axial end play by placing an iron pry bar or a similar item between suspension arm and strut
assembly and prying up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.
STRUT INSPECTION
Check for oil leakage, damage, and breakage of installation positions.
Wheel Alignment InspectionBES0003L
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen” conditions mean that fuel, engine coolant, and lubricant are full. A spare tire, a jack, hand tools and
mats are in designated positions.
PRELIMINARY CHECK
1. Check Tires for improper air pressure and wear.
2. Check Road wheels for runout. Refer to WT-3, "
ROAD WHEEL" .
3. Check Wheel bearing axial end play. Refer to FAX-5, "
WHEEL BEARING INSPECTION" .
4. Check Transverse link ball joint axial end play. Refer to FSU-14, "
INSPECTION AFTER REMOVAL" .
5. Check Strut operation.
6. Check Each mounting point of axle and suspension for looseness and deformation.
7. Check Each link, rod, and member for cracks, deformation and other damage.
8. Check Vehicle height (posture).
INSPECTION OF CAMBER, CASTER AND KINGPIN INCLINATION ANGLES.

Camber, caster, kingpin inclination angles cannot be adjusted.

Before inspection, mount wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so vehicle will remain horizontal.
Using a CCK Gauge
Install CCK gauge attachment [SST:KV991040S0] with the following procedure on wheel, then measure wheel
alignment.
1. Remove three wheel nuts, and install the guide bolts to hub
bolts.
2. Screw adapter into the plate until it contacts the plate tightly.
3. Screw center plate into the plate.
4. Insert plate on guide bolt. Put spring in, and then evenly screw
both guide bolt nuts. When fastening guide bolt nuts, do not
completely compress the spring.Axial end play : 0 mm (0 in)
