CYLINDER BLOCK
Revision: 2004 November 2004 FX35/FX45

Before loosening main bearing cap bolts, measure the crankshaft end play. Refer to EM-256, "CRANK-
SHAFT END PLAY" .

Loosen bolts in several different steps.
a. Remove cover attached to the rear left side of cylinder block
(next to the starter motor housing).
NOTE:
Bolts (No. 27 shown in the figure) are installed on the inside of
cover.
b. Loosen side bolts (M10) starting from 30 to 21 to remove.
c. Loosen main bearing cap sub bolts (M9) starting from 20 to 11 to
remove.
d. Loosen main bearing cap bolts (M12) starting from 10 to 1 to
remove.
e. Using main bearing cap remover (SST), remove main bearing
cap.
15. Remove crankshaft.
16. Remove main bearings and thrust bearings from cylinder block and main bearing caps.
CAUTION:
Identify installation positions, and store them without mixing them up.
17. If the pilot converter must be removed, remove it from the rear
end 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.

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 measured 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-260, "PISTON TO CYLINDER BORE CLEAR-
ANCE" .

If replacing connecting rod assembly, refer to EM-263, "CON-
NECTING ROD BEARING OIL CLEARANCE" to select the
connecting rod bearing.
Factory installed parts grading:

Service parts apply only to grade “0”.
Unit: mm (in)
*: After installing in connecting rod
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
Revision: 2004 November 2004 FX35/FX45
PRECAUTIONSPFP:00001
CautionAES000MZ

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: 2004 November 2004 FX35/FX45
FRONT SUSPENSION ASSEMBLYPFP:54010
On-Vehicle Inspection and ServiceAES000N3
Make sure the mounting conditions (looseness, back lash) of each component and component statues (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 installing and moving up/down between transverse link and steering knuckle
with an iron pry bar or something similar.
CAUTION:
Be careful not to damage ball joint boot.
STRUT INSPECTION
Check strut for oil leakage, damage and replace if necessary. Refer to FSU-11, "COIL SPRING AND STRUT" .
Wheel Alignment InspectionAES000N4
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
1. Check tires for improper air pressure and wear.
2. Check road wheels for runout.
3. Check wheel bearing axial end play.
4. Check transverse link ball joint axial end play.
5. Check strut operation.
6. Check each mounting part of axle and suspension for looseness and deformation.
7. Check each link, rod and member for cracks, deformation and other damage.
8. Check vehicle posture.
INSPECTION OF CAMBER, CASTER AND KINGPIN INCLINATION ANGLES

Camber, caster, kingpin inclination angles cannot be adjusted.

Before inspection, mount front 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) as following procedure in wheel, then measure wheel
alignment.
1. Remove wheel nuts (3), and install a guide bolt to hub bolt.
2. Screw adapter into plate body until it contacts body tightly.
3. Screw center plate into plate.
4. Insert plate on guide bolt. Put spring in, and then evenly screw
both guide bolt nut. When fastening guide bolt nut, do not com-
pletely compress spring.Axial end play : 0 mm (0 in)
