Remove main bearing caps 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 the “Method by Calculation”.
MAIN BEARING CRUSH HEIGHT
When main bearing cap is removed after being tightened to thespecified torque with main bearings installed, the tip end of bearing
must protrude. Refer to EM-123, "
Disassembly and Assembly" for
the tightening procedure.
If the standard is not met, replace main bearings.
CONNECTING ROD BEARING CRUSH HEIGHT
When connecting rod bearing cap is removed after being tightened to the specified torque with connecting rod bearings installed, the
tip end of bearing must protrude. Refer to EM-123, "
Disassembly
and Assembly" for the tightening procedure.
If the standard is not met, replace connecting rod bearings.
MAIN BEARING CAP BOLT OUTER DIAMETER
Measure the outer diameters (“d1”, “d2”) at two positions as shown
in the figure.
If reduction appears in “A” range, regard it as “d
2”.
If it exceeds the limit (large difference in dimensions), replace main bearing cap bolt with new one.

CYLINDER BLOCK
Measure the outer diameter “d”
at position shown in the figure.
If the reduction appears in a position other than “d”, regard it as “d”.
When “d” exceeds the limit (when it becomes thinner), replace connecting rod bolt with new one.
DRIVE PLATE
Check drive plate and signal plate for deformation or damage.CAUTION:
Do not disassemble drive plate.
Do not place drive plate with signal plate facing down.
When handling signal plate, take care not to damage or scratch it.
Handle signal plate in a manner that prevents it from becom-
ing magnetized.
If anything is found, replace drive plate.
OIL JET
Check nozzle for deformation and damage.
Blow compressed air from nozzle, and check for clogs.
If it is not satisfied, clean or replace oil jet.
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 reaction force.
If it is not satisfied, replace oil jet relief valve. Standard : 7.90 - 8.00 mm (0.3110 - 0.3150 in)
Limit : 7.75 mm (0.3051 in)
