• Secure flywheel
with a stopper plate [SST: KV11105210]
(A), and tighten mounting bolts.
• Using TORX socket (size E20), tighten mounting bolts.
CAUTION:
Never damage or scratch and contact surface for clutch disc of flywheel.

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.
• 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:
Never 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 clutch cover mounting bolt
to clutch cover mounting
hole, and place a torque wrench (A) 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 direc-
tion, and mark the movement amount on the mass on the tran-
saxle side.
4.
Measure the dimensions of movement amounts
and
on circumference of the flywheel on the tran-
saxle side.

3.
Remove pilot converter
, from the rear end of the crankshaft.
Use a pilot bush puller (commercial service tool)
, if neces-
sary.
INSTALLATION
1.
Install drive plate
, reinforcement plate
and pilot converter
as shown in figure.
• Using a drift of 33 mm (1.30 in) in diameter, press-fit pilot con-
verter into the end of crankshaft until it stops.
CAUTION:
Be careful not to damage or scratch and contact surface for clutch disc of flywheel.
2.
Install drive plate.
• Secure drive plate
with a stopper plate [SST: KV11105210]
(A), and remove mounting bolts.
• Using TORX socket (size E20), tighten mounting bolts.
• Install mounting bolts in diagonal order.

DRIVE PLATE DEFLECTION
• Measure the deflection of drive plate contact surface to torque con-
verter with a dial indicator (A).
• Measure the deflection at the area limited between 11.0 mm (0.433
in) dia and 20.6 mm (0.811 in) dia around hole
.
• If measured value is out of the standard, replace drive plate.
