MAIN BEARING CRUSH HEIGHT
When lower cylinder block is removed after being tightened to
the specified torque with main bearings installed, the tip end of
bearing must protrude. Refer to EM-94, "
ASSEMBLY" for the
tightening procedure.
If the standard is not met, replace main bearings.
CONNECTING ROD BEARING CRUSH HEIGHT
When connecting rod bearing cap is removed after being tight-
ened to the specified torque with connecting rod bearings
installed, the tip end of bearing must protrude. Refer to EM-94,
"ASSEMBLY" for the tightening procedure.
If the standard is not met, replace connecting rod bearings.
LOWER CYLINDER BLOCK MOUNTING BOLT OUTER DIAMETER
Perform only with M10 bolts.
Measure the outer diameters (“d1 ”, “d2” ) at two positions as
shown in the figure.
If reduction appears in “A” range, regard it as “d2 ”.
If it exceeds the limit (a large difference in dimensions), replace
lower cylinder block mounting bolt with a new one.
CONNECTING ROD BOLT OUTER DIAMETER
Measure the outer diameter “d” at position as shown in the fig-
ure.
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.Standard: There must be crush height.

Standard : There must be crush height.

FLYWHEEL DEFLECTION (M/T MODELS)
Measure the deflection of flywheel contact surface to clutch with
a dial indicator.
Measure the deflection at 210 mm (8.27 in) dia.
If measured value is out of the standard, replace flywheel.
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:
Do not 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 a 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 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.Standard : 0.45 mm (0.0177 in) or less.
PBIC2168E
