Exploded View

- Flywheel
Removal and Installation
REMOVAL
- Remove the engine and the transaxle assembly from the vehicle, and
separate the transaxle from the
engine. Refer to TM-28, "Exploded View".
- Remove flywheel.
- Secure flywheel (1) using Tool (A), and remove bolts using
suitable tool.
Tool number : KV11105210 (J-44716)

CAUTION:
- Do not disassemble flywheel.
- Do not place flywheel with signal plate facing down.
- When handling signal plate, take care not to damage or scratch.
- Handle signal plate, do so in a manner that prevents it from
becoming magnetized.
INSTALLATION
- Install flywheel.
- Secure flywheel (1) using Tool (A), and install bolts.
Tool number : KV11105210 (J-44716)

CAUTION:
Be careful not to damage or scratch the contact surface of flywheel.
Inspection
FLYWHEEL DEFLECTION
- Measure the deflection of flywheel contact surface to torque with a
dial indicator (A).
- Measure the deflection at 210 mm (8.27 in) diameter.
Limit : 0.45 mm (0.0177 in) or less.

- If measured value is out of the standard, replace flywheel.
- If a trace of burn or discoloration is found on the surface, repair it
with sandpaper.
MOVEMENT AMOUNT OF FLYWHEEL
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.
Standard : 1.8 mm (0.071 in) or less
- 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:
- Install clutch cover bolt (1) to clutch cover hole, and place a
torque wrench (A) on the extended line of the flywheel (2) center
line.
- Tighten bolt at a force of 9.8 NВ·m (1.0 kg-m, 87 in-lb) to keep it
from loosening.
- Put a mating mark on circumferences of the two flywheel
masses without applying any load (Measurement standard
points).
- Apply a force of 9.8 NВ·m (1.0 kg-m, 87 in-lb) in each direction,
and mark the movement amount on the mass on the transaxle
side.
- Measure the dimensions of movement amounts (A) and (B) on
circumference of the flywheel on the transaxle side.
Limit : 33.2 mm (1.307 in) or less.

- If measured value is out of the standard, replace flywheel.
