Method using plastigage
lRemove contamination such as 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.
CAUTION:
Never rotate crankshaft.
lRemove main bearings and bearings, and measure plastigage
width using scale on plastigage bag.
CAUTION:
If out of specification, take same action mentioned in “Method by measurement”.
lInstall 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.
MAIN BEARING CRUSH HETIGH
lWhen the bearing cap is removed after being tightened to the
specified torque with main bearings installed, the tip end of bear-
ing must protrude.
lIf out of specification, replace main bearings.
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.
CONNECTING ROD BOLT DEFORMATION
lInstall 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.
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 the measurement exceeds the limit, replace connecting rod
bolts and nuts.

OIL JET RELIEF VALVE
lUsing a clean plastic stick, press check valve in oil jet relief
valve. Make sure that valve moves smoothly with proper reac-
tion force.
lIf it is out of the standard, replace oil jet relief valve.
MOVEMENT AMOUNT OF FLYWHEEL
NOTE:
lInspection for double mass flywheel only.
lDo not disassembly double mass flywheel.
Flywheel Deflection
lMeasure deflection of flywheel contact surface to the clutch with a dial gauge.
lMeasure deflection at 210 mm (8.27 in) dia.
lWhen measured value exceeds the limit, replace flywheel with a
new one.
Movement Amount in Radial (rotation) Direction
lCheck 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.
lTighten bolt at a force of 9.8 N·m (1kg-m, 87 in-lb) to keep it from loosening.Standard : Deformation and damage.

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 (1kg-m, 87 in-lb) in each direction, and
mark the movement amount on the mass on the transmission
side.
4. Measure dimensions of movement amounts A and B on circum-
ference of the flywheel on the transmission side.
lWhen measured value is outside the standard, replace flywheel.Standard : 26.2 mm (1.031 in) or lessKBIA0297E
