ENGINE UNIT
• Measure the outer diameters (“d
1
”, “d
2”
) at two positions as shown.
• If reduction appears in places other than “B” range, regard it as
“d
2
”.
• If it exceeds the limit (a large difference in dimensions), replace
main bearing cap bolt with a new one.
CONNECTING ROD BOLT OUTER DIAMETER
• Measure the outer diameter “d” at position as shown.
• 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 bolt with a new one.
CLOGGED OR DAMAGED OIL FILTER (FOR INTAKE VALVE TIMING CONTROL)
• Make sure that there is no foreign material on the oil filter and
check it for clogging.
- Clean it if necessary.
• Check the oil filter for damage.
- Replace it if necessary.
FLYWHEEL DEFLECTION (M/T MODELS)
• Measure the deflection of flywheel contact surface to clutch 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.
A
: “d1” measuring position
B
: “d2” measuring position
Limit (“d
1
” – “d
2
”): 0.15 mm (0.0059 in)
PBIC4015E
Limit: 7.75 mm (0.3051 in)

PBIC3273J
Limit
: 0.45 mm (0.0177 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:
1.
Install clutch cover bolt (1) to clutch cover mating 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.
Limit: 33.2 mm (1.307 in) or less.

INFOID:0000000001337813
DESCRIPTION
• 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, follow the procedures.
HOW TO SELECT PISTON
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-219, "Inspection After Disassembly"
.
2.
Determine the bore grade by comparing the measurement with the values under the cylinder bore inner
diameter of the “Piston Selection Table”.
Selection points
Selection parts
Selection items
Selection methods
Between cylinder block and
crankshaft
Main bearing
Main bearing grade (bearing

Determined by match of cylin-
der block bearing housing
grade (inner diameter of hous-

nal)
Between crankshaft and con-
necting rod
Connecting rod bearing
Connecting rod bearing grade
(bearing thickness)
Combining service grades for
connecting rod big end diame-
ter and crankshaft pin outer di-
ameter determine connecting
rod bearing selection.
Between cylinder block and pis-
ton
Piston and piston pin assembly
(piston is available together with
piston pin as an assembly.)

HOW TO SELECT CONNECTING ROD BEARING
When New Connecting Rod and Crankshaft are Used
1.
Apply connecting rod big end diameter grade stamped (C) on
connecting rod side face to the row in the “Connecting Rod
Bearing Selection Table”.
2.
Apply crankshaft pin journal diameter grade stamped on crank-
shaft front side to the column in the “Connecting Rod Bearing
Selection Table”.
3.
Read the symbol at the cross point of selected row and column in the “Connecting Rod Bearing Selection
Table”.
4.
Apply the symbol obtained to the “Connecting Rod Bearing Grade Table” to select connecting rod bearing.
When Crankshaft and Connecting Rod are Reused
1.
Measure the dimensions of the connecting rod big end diameter and crankshaft pin journal diameter indi-
vidually. Refer to
EM-219, "Inspection After Disassembly"
and
