3. Cut cylinder bore.
●When any cylinder needs boring, all other cylinders must also be bored.
●Do not cut too much out of cylinder bore at a time. Cut only 0.05 mm (0.0020 in) or so at a time.
4. Hone cylinders to obtain specified piston-to-bore clearance.
5. Measure finished cylinder bore for out- of-round and taper.
●Measurement should be done after cylinder bore cools down.
CRANKSHAFT JOURNAL OUTER DIAMETER
Use micrometer to measure journal outer diameter.
CRANKSHAFT PIN OUTER DIAMETER
Use micrometer to measure pin outer diameter.
CRANKSHAFT OUT-OF-ROUND AND TAPER
●Using micrometer, measure each journal and pin at 4 points
shown in the figure.
●Out-of-round value is indicated by difference in dimensions
between directions X and Y at points A and B.

CONNECTING ROD BEARING OIL CLEARANCE
Method by Measurement
●Install connecting rod bearings to connecting rod and cap, and
tighten connecting nuts to the specified torque. Use inside
micrometer to measure connecting rod bearing inner diameter.
(Bearing clearance) = (Connecting rod bearing inner diameter) −
(Crankshaft pin outer diameter)
●If out of specifications, check connecting rod big end inner diam-
eter and crankshaft pin outer diameter, and select appropriate
connecting rod bearing to adjust clearance to specifications.
Refer to EM-207, "
HOW TO SELECT CONNECTING ROD
BEARING" .
Method Using Plastigage
●Remove contamination such as engine oil, dust completely from
crankshaft pins and each bearing surface.
●Cut plastigage slightly shorter than bearing width, place it in
crankshaft direction, avoiding oil holes.
●Install connecting rod bearings to caps, and tighten connecting
rod nuts to the specified torque.
CAUTION:
Never rotate crankshaft.
●Remove connecting rod caps and bearings, and measure plasti-
gage width using scale on plastigage bag.
CAUTION:
If out of specification, take same action mentioned in “Method by Measurement”.
MAIN BEARING OIL CLEARANCE
Method by Measurement
●Install main bearings to the cylinder block and bearing cap, and tighten the bolts to the specified torque.
Then, measure the inner diameter of the main bearings.
(Bearing clearance) = (Bearing inner diameter) − (Crankshaft journal outer diameter)
●If out of specification, check main bearing housing inner diameter and crankshaft journal outer diameter,
and select appropriate main bearing to adjust clearance to specifications. Refer to EM-208, "

Method Using Plastigage
●Remove contamination such as engine oil and dust completely
from crankshaft journals 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.
CAUTION:
Never rotate crankshaft.
●Remove main bearings and bearing caps, and measure plasti-
gage width using scale on plastigage bag.
CAUTION:
If out of specification, take same action mentioned in “Method by Measurement”.
MAIN BEARING CRUSH HEIGHT
●When the bearing cap is removed after being tightened to the
specified torque with main bearings installed, the tip end of bear-
ing must protrude.
●If out of specification, replace main bearings.
MAIN BEARING CAP BOLT DEFORMATION
●Measure the outer diameter of threaded area, d1 and d2, at the
points specified in the figure.
●When the necked point is identified at a point other than where
specified, measure at the point as d2.
●Calculate the difference between d1 and d2.
CONNECTING ROD BOLT DEFORMATION
●Install nuts to connecting rod bolts. Check that the nut can be
screwed smoothly on bolt threads by hand to the last thread on
the bolt.
●If the nut does not screw in smoothly, measure the outer diame-
ter of the bolt thread at the point specified in the figure.
●If a necked point is identified, measure at that point.
●If the measurement exceeds the limit, replace connecting rod
bolts and nuts.

OIL JET RELIEF VALVE
●Using a clean plastic stick, press check valve in oil jet relief
valve. Make sure that valve moves smoothly with proper reac-
tion force.
●If it is out of the standard, replace oil jet relief valve.
MOVEMENT AMOUNT OF FLYWHEEL
NOTE:
●Inspection for double mass flywheel only.
●Do not disassembly double mass flywheel.
Flywheel Deflection
●Measure deflection of flywheel contact surface to the clutch with a dial gauge.
●Measure deflection at 210 mm (8.27 in) dia.
●When measured value exceeds the limit, replace flywheel with a
new one.
Movement Amount in Radial (rotation) Direction
Check the movement amount in 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 kg-m, 87 in-lb) to keep it from loosening. Standard : Deformation and damage.
