11. Using piston ring expander (commercial service tool), install pis-
ton rings.
CAUTION:
Be careful not to damage piston.

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 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
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.

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 cap.

Match the stamped cylinder number marks on connecting rod
with those on cap to install.Stamped mark

15. Tighten the connecting rod nuts as follows:
a. Apply engine oil to the threads and seats of connecting rod bolts
and nuts.
b. Tighten nuts.
c. Then tighten all nuts 60 degrees clockwise. (Angle tightening)
CAUTION:
Use angle wrench (SST) to check tightening angle. Do not
make judgment by visual inspection.

After tightening nuts, make sure that the crankshaft rotates
smoothly.

Check the connecting rod side clearance. Refer to EM-256, "CONNECTING ROD SIDE CLEARANCE"
.
16. Install knock sensor.

Install it with its connector facing the rear of engine.

Install the sub-harness with its shorter branch line to the right
bank.
CAUTION:

Do not tighten mounting bolts while holding connector.

If any impact by dropping is applied to knock sensor,
replace it with new one.
NOTE:

Make sure that there is no foreign material on the cylinder
block mating surface and the back surface of the knock sen-
sor.

Make sure that the knock sensor does not interfere with other parts.
17. Install in the reverse order of removal after this step.
18. Remove engine assembly from engine stand.
19. Install drive plate.

Align guide pin of crankshaft rear end with pin holes of each
parts to install.

Install drive plate, reinforcement plate and pilot converter (if
not installed in step 4) as shown in the figure.

Face chamfered or rounded edge side to crankshaft.

Holding ring gear with ring gear stopper [SST: J-45476].

Tighten mounting bolts crosswise over several times.

When install pilot converter, using drift [outer diameter:
approx. 35 mm (1.38 in)]. Press-fit as far as it will go. : 14.7 N·m (1.5 kg-m, 11 ft-lb)

When replacing piston and piston pin assembly, refer to EM-260, "PISTON TO CYLINDER BORE
CLEARANCE" .
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 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 cylinder bore inner diameter is within specifica-
tion. Refer to EM-260, "
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 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:

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)
