CYLINDER BLOCK

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.
14. Remove piston from connecting rod with the following procedure:

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.

During the removal operation, always be careful to prevent vehicle from falling off the lift due to
changes in the center of gravity.

If necessary, support vehicle by setting a jack or equivalent tool at the rear.
8. Remove starter motor. Refer to SC-23, "
STARTING SYSTEM" .
9. Separate engine and transaxle and transfer assembly. Refer to MT-19, "
