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. (VQ23DE)
Install second ring with the stamped surface facing upward.
(VQ35DE)
NOTE:
If there is no stamped mark on piston ring, no specific orientation is required for installation.
13. 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 connecting rod bearing stopper protru-
sion with cutout of connecting rod and connecting rod bearing
cap to install.
Ensure the oil hole on connecting rod and that on the corre-
sponding bearing are aligned.
14. Install piston and connecting rod assembly to crankshaft.
Position 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 number on connecting rod to install.
Be sure that front mark on piston head is facing front of engine.
Using piston ring compressor (SST) or suitable tool, install
piston with the front mark on the piston head facing the front
of engine.
CAUTION:
Be careful not to damage the cylinder wall and crankshaft
pin, resulting from an interference of the connecting rod big
end.
15. Install connecting rod bearing caps.Stamped mark:

Match the stamped cylinder number marks on connecting rod
with those on connecting rod bearing cap to install.
Be sure that front mark on connecting rod bearing cap is fac-
ing front of engine.
16. Tighten connecting rod nuts (VQ23DE) or connecting rod bolts (VQ35DE) as follows:
a. Apply engine oil to the threads and seats of connecting rod nuts or bolts.
b. Tighten connecting rod nuts or bolts.
c. Then tighten all connecting rod nuts or bolts 90 degrees clock-
wise. (Angle tightening)
CAUTION:
Use angle wrench [SST: KV10112100] to check tightening
angle. Do not make judgment by visual inspection.
After tightening connecting rod nuts or bolts, make sure that
crankshaft rotates smoothly.
17. Install rear oil seal retainer to cylinder block.
Apply new engine oil to both oil seal lip and dust seal lip.
Apply a continuous bead of liquid gasket with tube presser
[SST: WS39930000] to rear oil seal retainer as shown in the
figure.
Use Genuine Liquid Gasket or equivalent.
CAUTION:
Replace with a new part.
NOTE:
Regard both rear oil seal and retainer as an assembly.
18. Install pilot converter.
With drift [outer diameter: approx. 33 mm (1.30 in)], press-fit
as far as it will go.

When replacing piston and piston pin assembly, refer to EM-240, "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 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 the specifi-
cation. Refer to EM-249, "

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)
