bearing must protrude (B). Refer to 

EM-112, "Disassembly and

Assembly"

.

• If the standard is not met, replace main bearings.

CONNECTING ROD BEARING CRUSH HEIGHT

• When connecting rod cap is removed after being tightened to the

specified torque with connecting rod bearings (1) installed, the tip
end of bearing must protrude (B). Refer to 

EM-112, "Disassembly

and Assembly"

.

• If the standard is not met, replace connecting rod bearings.

MAIN BEARING CAP BOLT OUTER DIAMETER 

• Measure the outer diameters (d

) and (d

) at two positions as

shown in the figure.

• If reduction appears in places other than (B) range, regard it as

(d

• Measure the outer diameter (d) at position as shown in the figure.
• If reduction appears in a position other than (d), regard it as (d).

• When (d) exceeds the limit (when it becomes thinner), replace

connecting rod cap bolt with a new one.

FLYWHEEL DEFLECTION (M/T MODELS)

• 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.

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:

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 (1) to clutch cover mounting
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 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.

HOW TO SELECT PISTON AND BEARING

HOW TO SELECT PISTON AND BEARING

Description

INFOID:0000000009753623

• The identification grade stamped on each part is the grade for the dimension measured in new condition.

This grade cannot apply to reused parts. 

• For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the

measurement with the values of each selection table.

• For details of the measurement method of each part, the reuse standards and the selection method of the

selective fitting parts, refer to the text.

Piston

INFOID:0000000009753624

WHEN NEW CYLINDER BLOCK IS USED

• Check the cylinder bore grade on rear left side of cylinder block (L),

and select piston of the same grade.

• If there is a correction stamp mark on the cylinder block, use it as a

correct reference.

WHEN CYLINDER BLOCK IS REUSED

1.

Measure the cylinder bore inner diameter. Refer to 

EM-141, "Cylinder Block"

.

2.

Determine the bore grade by comparing the measurement with the values under the cylinder bore inner
diameter of the “Piston Selection Table”.
