MAIN BEARING OIL CLEARANCE
Method by Measurement

Install main bearings to cylinder block and bearing cap, and
tighten the bolts to the specified torque. Refer to EM-235,
"ASSEMBLY" . Then, measure the inner diameter of main bear-
ings.
(Bearing clearance) = (Bearing inner diameter) − (Crankshaft
main journal diameter)

If out of the standard, check main bearing housing inner diame-
ter and crankshaft main journal diameter, and select appropriate
main bearing to adjust clearance to specifications. Refer to EM-
244, "HOW TO SELECT MAIN BEARING" .
Method of Using Plastigage

Remove contamination such as engine oil and dust completely
from crankshaft main journal and each bearing surface.

Cut plastigage slightly shorter than bearing width. Place it in
crankshaft turning direction, avoiding oil holes.

Install main bearings and bearing cap and tighten to the speci-
fied torque. Refer to EM-235, "
ASSEMBLY" for the tightening
procedure.
CAUTION:
Do not rotate crankshaft.

Remove main bearings and bearing caps, and measure plasti-
gage width using scale on plastigage bag.
NOTE:
If out of specification, take same action mentioned in “Method by Measurement”.
CRUSH HEIGHT OF MAIN BEARING

When bearing cap is removed after being tightened to the speci-
fied torque with main bearings installed, the tip end of bearing
must protrude. Refer to EM-235, "
ASSEMBLY" .

If out of the standard, replace main bearings.
CRUSH HEIGHT OF CONNECTING ROD BEARING

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-235,
"ASSEMBLY" .

If out of the standard, replace connecting rod bearings.Standard : 0.039 - 0.066 mm (0.0015 - 0.0026 in)

FLYWHEEL DEFLECTION

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
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.
PBIC2646E
Standard : 1.3 mm (0.051 in) or less
Standard: 26.2 mm (1.031 in) or less.
