WARNING:

Situate vehicle on a flat and solid surface.

Place chocks at front and back of rear wheels.

For engines not equipped with engine slingers, attach proper slingers and bolts described in
PARTS CATALOG.
CAUTION:

Always be careful to work safely, avoid forceful or uninstructed operations.

Do not start working until exhaust system and engine coolant are cool enough.

If items or work required are not covered by the engine section, refer to the applicable sections.

Always use the support point specified for lifting.

Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for
unavoidable reasons, support at the rear axle jacking point with transmission jack or similar tool
before starting work, in preparation for the backward shift of center of gravity.

For supporting points for lifting and jacking point at rear axle, refer to GI-36, "Garage Jack and
Safety Stand" .

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.

Using a piston ring compressor (special service tool) or suit-
able tool, install piston with the front mark on the piston head
facing the front of the engine.
CAUTION:
Be careful not to damage the cylinder wall and crankshaft
pin, resulting from an interference of the connecting rod
big end.
11. Install connecting rod cap.

Match the stamped cylinder number marks on connecting rod
with those on connecting rod cap to install.
12. Tighten connecting rod bolt with the following procedure:
a. Apply new engine oil to the threads and seats of connecting rod bolts.
b. Tighten bolts.
c. Then turn all bolts 90 degrees clockwise (Angle tightening).
CAUTION:
Check and confirm the tightening angle by using an angle
wrench (special service tool) or protractor. Avoid judge-
ment by visual inspection without the tool.

After tightening connecting rod bolt, make sure that crankshaft rotates smoothly.

Check the connecting rod side clearance. Refer to EM-107, "CONNECTING ROD SIDE CLEARANCE" .
13. Install flywheel (M/T models) or drive plate (A/T models).
CAUTION:
Make sure that dowel pin is installed at the rear end of crankshaft.

When installing flywheel (M/T models) or drive plate (A/T models) to crankshaft, make sure that align
crankshaft side dowel pin with flywheel/drive-plate side dowel pin hole correctly.
CAUTION:
If these are not aligned correctly, engine runs roughly and “MI” turns on.

Secure crankshaft with a stopper plate, and tighten mounting bolts crosswise over several times.

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.
