lIf corrected, measure the bearing oil clearance of the corrected journal and/or pin. Then select the main
bearing or connecting rod bearing. Refer toEM-132, "
MAIN BEARING OIL CLEARANCE"and/orEM-
131, "CONNECTING ROD BEARING OIL CLEARANCE".
CRANKSHAFT RUNOUT
lPlace V-block onto surface plate to support journals at both ends
of crankshaft.
lPosition dial gauge vertically onto No. 3 journal.
lRotate crankshaft to read needle movement on dial gauge.
(Total indicator reading)
lIf it exceeds the limit, replace crankshaft.
CONNECTING ROD BEARING OIL CLEARANCE
Method by Measurement
lInstall connecting rod bearings to connecting rod and cap, and
tighten connecting nuts to the specified torque. Refer toEM-114,
"ASSEMBLY". Use inside micrometer to measure connecting
rod bearing inner diameter.
(Bearing clearance) = (Connecting rod bearing inner diameter)-
(Crankshaft pin outer diameter)
lIf clearance exceeds the standard, select proper connecting rod
bearing according to connecting rod big end diameter and
crankshaft pin outer diameter to obtain specified bearing oil
clearance. Refer toEM-122, "
HOW TO SELECT CONNECTING
ROD BEARING".
Method of Using Plastigage
lRemove contamination such as engine oil, dust completely from
crankshaft pins and each bearing surface.
lCut plastigage slightly shorter than bearing width, place it in
crankshaft direction, avoiding oil holes.
lInstall connecting rod bearings to caps, and tighten connecting
rod nuts to the specified torque.
CAUTION:
Do not rotate crankshaft.
lRemove connecting rod caps and bearings, and measure plasti-
gage width using scale on plastigage bag.

MAIN BEARING OIL CLEARANCE
Method by Measurement
lInstall main bearings to cylinder block and bearing cap, and
tighten the bolts to the specified torque. Refer toEM-114,
"ASSEMBLY". Then, measure the inner diameter of main bear-
ings.
(Bearing clearance) = (Bearing inner diameter)-(Crankshaft
journal outer diameter)
lIf out of the standard, check main bearing housing inner diame-
ter and crankshaft journal outer diameter, and select appropriate
main bearing to adjust clearance to specifications. Refer toEM-
123, "HOW TO SELECT MAIN BEARING".
Method of Using Plastigage
lRemove contamination such as engine oil and dust completely
from crankshaft journals and each bearing surface.
lCut plastigage slightly shorter than bearing width. Place it in
crankshaft turning direction, avoiding oil holes.
lInstall main bearings and bearing cap and tighten to the speci-
fied torque. Refer toEM-114, "
ASSEMBLY"for the tightening
procedure.
CAUTION:
Do not rotate crankshaft.
lRemove 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
lWhen bearing cap is removed after being tightened to the speci-
fied torque with main bearings installed, the tip end of bearing
must protrude. Refer toEM-114, "
ASSEMBLY".
lIf out of the standard, replace main bearings.
CRUSH HEIGHT OF CONNECTING ROD BEARING
lWhen 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 toEM-114,
"ASSEMBLY".
lIf out of the standard, replace connecting rod bearings.Standard : 0.047 - 0.077 mm (0.0019 - 0.0030 in)

MAIN BEARING CAP BOLT DEFORMATION
lMeasure the outer diameter of threaded area, d1 and d2, at the
points specified in the figure.
lWhen the necked point is identified at a point other than where
specified, measure at the point as d2.
lCalculate the difference between d1 and d2.
lIf it exceeds the limit, replace main bearing cap bolt.
CONNECTING ROD BOLT DEFORMATION
lInstall nuts to connecting rod bolts. Make sure that the nut can
be screwed smoothly on bolt threads by hand to the last thread
on the bolt.
lIf the nut does not screw in smoothly, measure the outer diame-
ter of the bolt thread at the point specified in the figure.
lIf a necked point is identified, measure at that point.
lIf it exceeds the limit, replace connecting rod bolts and nuts.

lMeasure the deflection of flywheel contact surface to clutch with
a dial indicator.
lMeasure the deflection at 210 mm (8.27 in) dia.
lIf 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
lMeasure 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.
lIf 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.
lTighten 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 the dimensions of movement amounts “A” and “B” on
circumference of the flywheel on the transmission side.
lIf measured value is out of the standard, replace flywheel.
DRIVE PLATE
lCheck drive plate and signal plate for deformation or cracks.
CAUTION:
lDo not disassemble drive plate.
lDo not place drive plate with signal plate facing down.
lWhen handling signal plate, take care not to damage or
scratch it.
lHandle signal plate in a manner that prevents it from
becoming magnetized.
lIf anything is found, replace drive plate.Standard : 0.45 mm (0.0177 in) or less.
