CONNECTING ROD BOLT OUTER DIAMETER

Measure the outer diameter (“a”, “b” and “c”) at the position
shown in the figure.

Obtain a mean value (d) of (a) and (b).

Subtract (c) from (d).

If it exceeds the limit (large difference in dimensions), replace
the bolt with new one.
FLYWHEEL DEFLECTION (M/T MODELS)

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

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

If the measured value is out of the standard, replace flywheel.
MOVEMENT AMOUNT OF FLYWHEEL (M/T MODELS)
CAUTION:
Do not disassemble double mass flywheel.
Movement Amount of Radial (Rotation) Direction
Check the movement amount of radial (rotation) direction as follows:
1. Install 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 transmis-
sion side.
4. Measure dimensions of movement amounts “A” and “B” on cir-
cumference of flywheel on the transmission side.

If the measured value is out of the standard, replace flywheel.
a : Value at the end of the smaller diameter of the bolt
b : Value at the end of the smaller diameter of the bolt (opposite side “a”)
c : Value of the smallest diameter of the smaller of the bolt
Limit (“d” − “c”) : 0.09 mm (0.0035 in)
