NOTE:
The flywheel, two block construction, allows movement in response to transaxle side pressure, or when
twisted in its rotational direction. Therefore, some amount of noise is normal.
10. Remove pilot converter using pilot bushing puller (special ser-
vice tool) or suitable tool. (A/T models)
NOTE:
M/T models have no pilot bushing.
11. Remove piston and connecting rod assembly with the following procedure:

Before removing piston and connecting rod assembly, check the connecting rod side clearance. Refer
to EM-107, "
CONNECTING ROD SIDE CLEARANCE" .
a. Position crankshaft pin corresponding to connecting rod to be removed onto the bottom dead center.
b. Remove connecting rod cap.
c. Using a hammer handle or similar tool, push piston and connect-
ing rod assembly out to the cylinder head side.
CAUTION:
Be careful not to damage the cylinder wall, resulting from
an interference of the connecting rod big end.
12. Remove connecting rod bearings.
CAUTION:
When removing them, note the installation position. Keep them in the correct order.
13. Remove piston rings form piston.

Use a piston ring expander (commercial service tool).
CAUTION:

When removing piston rings, be careful not to damage
the piston.

Be careful not to damage piston rings by expanding
them excessively.

ii. Turn M10 bolts 60 degrees clockwise (angle tightening) in order
from No. 1 to 10 in the figure.
CAUTION:
Check and confirm the tightening angle by using an angle
wrench (special service tool) or protractor. Avoid judgment
by visual inspection without the tool.

After installing mounting bolts, make sure that crankshaft can be rotated smoothly by hand.

Wipe off completely any protruding liquid gasket on front side of engine.

Check crankshaft end play. Refer to EM-107, "CRANKSHAFT END PLAY" .
7. Install piston to connecting rod with the following procedure:

HOW TO SELECT PISTON
When New Cylinder Block is Used

Check the cylinder bore grade on rear left side of cylinder block,
and select piston of the same grade.

If there is a corrected stamp mark on the cylinder block, use it as
a correct reference.
When Cylinder Block is Reused
1. Measure the cylinder bore inner diameter. Refer to E M - 111 , "Cylinder Bore Inner Diameter" .
2. Determine the bore grade by comparing the measurement with the values under the cylinder bore inner
diameter of the “Piston Selection Table”.
3. Select piston of the same grade.
Piston Selection Table
Unit: mm (in)
NOTE:

There is no piston grade “1”.

Piston is available together with piston pin as an assembly.

The piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts,
no grades can be selected. (Only grade “0” is available.)
HOW TO SELECT CONNECTING ROD BEARING
When New Connecting Rod and Crankshaft are Used
1. Apply connecting rod big end diameter grade stamped on con-
necting rod side face to the row in the “Connecting Rod Bearing
Selection Table”.
2. Apply crankshaft pin journal diameter grade stamped on crank-
shaft front side to the column in the “Connecting Rod Bearing
Selection Table”.

If it exceeds the limit, replace connecting rod assembly.
CONNECTING ROD BIG END DIAMETER

Install connecting rod cap without connecting rod bearing installed, and tightening connecting rod bolts to
the specified torque. Refer to EM-94, "
ASSEMBLY" for the tightening procedure.

Measure the inner diameter of connecting rod big end with an
inside micrometer.

If out of the standard, replace connecting rod assembly.

FLYWHEEL DEFLECTION (M/T MODELS)

Measure the deflection of flywheel contact surface to clutch with
a dial indicator.

Measure the deflection at 210 mm (8.27 in) dia.

If measured value is out of the standard, replace flywheel.
CAUTION:
When measuring, keep magnetic fields (such as dial indicator
stand) away from signal plate of the rear end of crankshaft.
MOVEMENT AMOUNT OF FLYWHEEL (M/T MODELS)
CAUTION:
Do not disassemble double mass flywheel.
Movement Amount of Thrust (Fore-and-Aft) Direction

Measure the movement amount of thrust (fore-and-aft) direction when 100 N (10.2 kg, 22 lb) force is
added at the portion of 125 mm (4.92 in) radius from the center of flywheel.

If measured value is out of the standard, replace flywheel.
Movement Amount in Radial (Rotation) Direction
Check the movement amount of radial (rotation) direction with the following procedure:
1. Install a bolt to clutch cover mounting hole, and place a torque wrench on the extended line of the flywheel
center line.

Tighten bolt at a force of 9.8 N·m (1.0 kg-m, 87 in-lb) to keep it from loosening.
2. Put a mating mark on circumferences of the two flywheel
masses without applying any load (Measurement standard
points).
3. Apply a force of 9.8 N·m (1.0 kg-m, 87 in-lb) in each direction,
and mark the movement amount on the mass on the transaxle
side.
4. Measure the dimensions of movement amounts “A” and “B” on
circumference of the flywheel on the transaxle side.

If measured value is out of the standard, replace flywheel.Standard : 0.45 mm (0.0177 in) or less.

PRECAUTIONS

[YD22DDTi]PRECAUTIONSPFP:00001
Precautions for Draining Engine CoolantEBS00LQZ
Drain engine coolant when engine is cooled.
Precautions for Disconnecting Fuel PipingEBS00LR0

Before starting work, make sure no fire or spark producing items are in the work area.

After disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and DisassemblyEBS00LR1

When instructed to use special service tools, use the specified tools. Always be careful to work safely,
avoid forceful or uninstructed operations.

Exercise maximum care to avoid damage to mating or sliding surfaces.

Cover openings of engine system with tape or the equivalent, if necessary, to seal out foreign materials.

Mark and arrange disassembly parts in an organized way for easy troubleshooting and re-assembly.

When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, do exactly as specified.
Precautions for Inspection, Repair and ReplacementEBS00LR2
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precautions for Assembly and InstallationEBS00LR3

Use torque wrench to tighten bolts or nuts to specification.

When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is speci-
fied, do exactly as specified.

Replace with new liquid gasket, packing, oil seal or O-ring.

Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins,
make sure that dowel pins are installed in the original position.

Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for
any restriction and blockage.

Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, engine oil sliding surfaces well.

Release air within route when refilling after draining coolant.

After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust systems for leakage.
Parts Requiring Angle TighteningEBS00LR4

Use an angle wrench (special service tool: KV10112100) for the final tightening of the following engine
parts:
–Cylinder head bolts
–Main bearing cap bolts
–Connecting rod cap nuts
–Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angle
tightening)

Do not use a torque value for final tightening.

The torque value for these parts are for a preliminary step.

Ensure thread and seat surfaces are clean and coated with engine oil.
