Assemble so that the front mark on the piston crown and the
oil holes and the cylinder No. on the connecting rod are posi-
tioned as shown.
c. Install the snap ring to the grooves of the piston front side.
Insert it fully into groove to install.
After installing, make sure the connecting rod moves
smoothly.
11. Install the piston rings.
CAUTION:
Be careful not to damage the piston.
Position each ring with the gap as shown, referring to the pis-
ton front mark.
Install the second ring with the stamped surface facing
upward.
12. Install the connecting rod bearings to the connecting rod and the
connecting rod cap.
When installing the connecting rod bearings, apply engine oil
to the bearing surface (inside). Do not apply oil to the back
surface, but thoroughly clean it.
When installing, align the connecting rod bearing stopper pro-
trusion with the cutout of the connecting rod to install.
Check the oil holes on the connecting rod and those on the
corresponding bearing are aligned.
13. Install the piston and connecting rod assembly to the crankshaft
using Tool.
Position the crankshaft pin corresponding to the 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 the con-
necting rod to install.
Install the piston with the front mark on the piston crown fac-
ing the front of the engine.
CAUTION:
Be careful not to damage the crankshaft pin, resulting from an interference of the connecting
rod big end.

14. Install the connecting rod cap.
Match the stamped cylinder number marks on the connecting
rod with those on the cylinder cap to install.
15. Tighten the connecting rod bolts using Tool.
Apply engine oil to the threads and seats of the connecting
rod bolts.
After tightening the bolts, make sure that the crankshaft
rotates smoothly.
Check the connecting rod side clearance. Refer to EM-89, "CONNECTING ROD SIDE CLEARANCE"
16. Install knock sensor.
CAUTION:
If the knock sensor is dropped, replace it with a new one.
Make sure that there is no foreign material on the cylinder
block mating surface and the back surface of the knock sen-
sor.
Install it with its connector facing the center of cylinder block
side.
Do not tighten the knock sensor bolts while holding the con-
nector.
Make sure that the knock sensor does not interfere with other
parts.
Position sub-harness as shown before installing intake mani-
fold.
17. Installation of the remaining components is in the reverse order of removal.
18. Remove engine assembly from engine stand.

REMOVAL
1. Remove wheel and tire using power tool.
2. Remove engine under cover using power tool.
3. Remove wheel sensor harness from mount on knuckle.
CAUTION:
Do not pull on wheel sensor harness.
4. Without disassembling the hydraulic lines, remove brake caliper using power tool. Reposition it aside with
wire. Refer to BR-22, "
Removal and Installation of Brake Caliper and Disc Rotor" .
NOTE:
Avoid depressing brake pedal while brake caliper is removed.
5. Remove coil spring and shock absorber assembly using power tool. Refer to FSU-10, "
Removal and
Installation" .
6. Separate upper link ball joint stud from steering knuckle using
Tool.
Support lower link with jack.
7. Remove cotter pin, then remove drive shaft nut.
8. Remove drive shaft mounting bolts from front final drive.
9. Remove drive shaft from wheel hub and bearing assembly.
CAUTION:
When removing drive shaft, do not apply an excessive
angle to drive shaft joint. Also be careful not to exces-
sively extend slide joint.
INSPECTION AFTER REMOVAL
Move joint up, down, left, right, and in axial direction. Check for any rough movement or significant loose-
ness.
Check boot for cracks or other damage, and for grease leakage.
If damaged, disassemble drive shaft to verify damage, and
repair or replace as necessary.

3. Attach liquid gasket tube to Tool.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-45, "
Recommended Chemical Products and Sealants" .
4. Apply liquid gasket without breaks to the specified location with
the specified dimensions.
If there is a groove for liquid gasket application, apply liquid
gasket to the groove.
As for bolt holes, normally apply liquid gasket inside the
holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of this manual.
Within five minutes of liquid gasket application, install the mat-
ing component.
If liquid gasket protrudes, wipe it off immediately.
Do not retighten nuts or bolts after the installation.
After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe
them.Tool number : WS39930000 ( — )

PRECAUTIONSPFP:00001
PrecautionsEES0010D
When installing the rubber bushings, the final tightening must be done under unladen condition and with
the tires on level ground. Oil will shorten the life of the rubber bushings, so wipe off any spilled oil immedi-
ately.
Unladen condition means the fuel tank, engine coolant and lubricants are at the full specification. The
spare tire, jack, hand tools, and mats are in their designated positions.
After installing suspension components, check the wheel alignment.
Lock nuts are not reusable. Always use new lock nuts for installation. New lock nuts are pre-oiled, do not
apply any additional lubrication.
