CRANKSHAFT RUNOUT
●Place a V-block on a precise flat table to support the journals on
the both end of the crankshaft.
●Place a dial gauge straight up on the No. 3 journal.
●While rotating the crankshaft, read the movement of the pointer
on the dial gauge. (Total indicator reading)
CONNECTING ROD BEARING OIL CLEARANCE
Method of Measurement
●Install the connecting rod bearings to the connecting rod and the
cap, and tighten the connecting rod bolts to the specified torque.
Using a inside micrometer measure the inner diameter of con-
necting rod bearing.
(Oil clearance) = (Inner diameter of connecting rod bearing) –
(Outer diameter of crankshaft pin)
●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-83, "
HOW TO SELECT CONNECTING ROD BEARING" .
Method of Using Plastigage
●Remove engine oil and dust on the crankshaft pin and the sur-
faces of each bearing completely.
●Cut a plastigage slightly shorter than the bearing width, and
place it in crankshaft axial direction, avoiding oil holes.
●Install the connecting rod bearings to the connecting rod cap,
and tighten the connecting rod bolts to the specified torque.
CAUTION:
Never rotate the crankshaft.
●Remove the connecting rod cap and bearings, and using the
scale on the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is same as that described in “Method of Mea-
surement”.
MAIN BEARING OIL CLEARANCE
Method of Measurement
●Install the main bearings to the cylinder block and bearing cap. Measure the main bearing inner diameter
with the bearing cap bolt tightened to the specified torque.
(Oil clearance) = (Inner diameter of main bearing) – (Outer diameter of crankshaft journal)
●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-85, "

CYLINDER BLOCK
Method of Using Plastigage
●Remove engine oil and dust on the crankshaft journal and the
surfaces of each bearing completely.
●Cut a plastigage slightly shorter than the bearing width, and
place it in crankshaft axial direction, avoiding oil holes.
●Tighten the main bearing bolts to the specified torque.
CAUTION:
Never rotate the crankshaft.
●Remove the bearing cap and bearings, and using the scale on
the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in “Method of 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 the standard is not met, replace main bearings.
OUTER DIAMETER OF LOWER CYLINDER BLOCK MOUNTING BOLT
●Perform only with M10 (0.39 in) bolts.
●Measure outer diameters (d1, d2) at two positions shown in the figure.
●Measure d2 at a point within block A.
●When the value of d1- d2 exceeds the limit (a large difference in
dimensions), replace the bolt with a new one.
OUTER DIAMETER OF CONNECTING ROD BOLT
●Measure outer diameter (d) at position shown in the figure.
●When “d ” exceeds the limit (when it becomes thinner), replace
the bolt with a new one.

MOVEMENT AMOUNT OF FLYWHEEL (M/T MODELS)
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 it 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 (1.0 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 dimensions of movement amounts A and B on circum-
ference of the flywheel on the transaxle side.
●When measured value is outside the standard, replace fly-
wheel.Standard : 0.45 mm (0.0177 in) or less.
Limit : 1.3 mm (0.051 in) or less.

PRECAUTIONS
[YD22DDTi]PRECAUTIONSPFP:00001
Precautions for Drain Engine CoolantEBS00LQZ
Drain engine coolant when engine is cooled.
Precautions for Disconnecting Fuel PipingEBS00LR0
●Before starting work, make sure no fire or spark producing items are in the work area.
●Release fuel pressure before disassembly.
●After disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and DisassemblyEBS00LR1
●When instructed to use special service tools, use the specified tools. Always be careful to work safely,
avoid forceful or uninstructed operations.
●Exercise maximum care to avoid damage to mating or sliding surfaces.
●Cover openings of engine system with tape or the equivalent, if necessary, to seal out foreign materials.
●Mark and arrange disassembly parts in an organized way for easy troubleshooting and re-assembly.
●When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, do exactly as specified.
Precautions for Inspection, Repair and ReplacementEBS00LR2
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precautions for Assembly and InstallationEBS00LR3
●Use torque wrench to tighten bolts or nuts to specification.
●When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is speci-
fied, do exactly as specified.
●Replace with new liquid gasket, packing, oil seal or O-ring.
●Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for
any restriction and blockage.
●Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, engine oil sliding surfaces well.
●Release air within route when refilling after draining coolant.
●After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust systems for leakage.
Parts Requiring Angular TighteningEBS00LR4
●Use an angle wrench for the final tightening of the following engine parts:
–Cylinder head bolts
–Main bearing cap bolts
–Connecting rod cap nuts
–Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular
tightening)
●Do not use a torque value for final tightening.
●The torque value for these parts are for a preliminary step.
●Ensure thread and seat surfaces are clean and coated with engine oil.
