DISASSEMBLY
1. Remove engine assembly from vehicle, and separate front suspension member and transmission from
engine. Refer to EM-101, "
ENGINE ASSEMBLY" .
2. Remove engine mounting brackets (RH and LH). Refer to EM-101, "
ENGINE ASSEMBLY" .
3. Remove the parts that may restrict installation of engine to widely use engine stand.
NOTE:
The procedure is described assuming that you use a widely use engine stand holding the surface, to
which transmission is installed.

Remove clutch cover and clutch disk (M/T models). Refer to CL-16, "CLUTCH DISC, CLUTCH
COVER" .

Remove flywheel (M/T models) or drive plate (A/T models). Fix crankshaft with a ring gear stopper
[SST: KV10118600 (J-48641)], and remove mounting bolts.

Loosen mounting bolts in diagonal order.

Check for deformation or damage (A).
CAUTION:

Do not disassemble drive plate.

Never place drive plate with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.
4. Remove pilot bushing (M/T models) or pilot converter (A/T mod-
els) using pilot bushing puller [SST: ST16610001 (J-23907)] (A)
or suitable tool as necessary.
5. Lift the engine with hoist to install it onto the widely use engine stand.

A widely use engine stand can be used.
CAUTION:
Use engine stand that has a load capacity [approximately
220 kg (485 lb) or more] large enough for supporting the
engine weight.
NOTE:
This example is engine stand for holding at transmission
mounting side with flywheel (M/T models) or drive plate (A/T
models) removed.
6. Drain engine oil. Refer to LU-7, "
Changing Engine Oil" .

Flywheel (M/T models)

When installing flywheel to crankshaft, be sure to correctly
align crankshaft side dowel pin and flywheel side dowel pin
hole.
CAUTION:
If these are not aligned correctly, engine runs roughly
and “MIL” turns on.

There is a mating mark on the clutch cover side of flywheel.
Refer it during installation.

Holding ring gear with ring gear stopper [SST: KV11018600 (J-48641)], tighten securing bolts with
TORX socket (size: T55, commercial service tool).

Tighten the mounting bolts crosswise over several times.
Drive plate (A/T models)

When installing drive plate to crankshaft, be sure to correctly align crankshaft side dowel pin and drive
plate side dowel pin hole.
CAUTION:
If these are not aligned correctly, engine runs roughly and “MIL” turns on.

Install drive plate and reinforcement plate as shown in the fig-
ure.

Holding ring gear with ring gear stopper [SST: KV10118600
(J-48641)].

Tighten the mounting bolts crosswise over several times.

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)
PBIC5025E
Standard : 0.45 mm (0.0177 in) or less
PBIC2168E
Standard : 24 mm (0.94 in) or less
