Remove main bearing caps and bearings, and using scale on
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”.
CRUSH HEIGHT OF MAIN BEARING

When main bearing cap is removed after being tightened to the
specified torque with main bearings installed, the tip end of bear-
ing must protrude. Refer to EM-233, "
ASSEMBLY" for the tight-
ening procedure.

If the standard is not met, replace main bearings.
CRUSH HEIGHT OF CONNECTING ROD BEARING

When 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 to EM-233,
"ASSEMBLY" for the tightening procedure.

If the standard is not met, replace connecting rod bearings.
MAIN BEARING CAP BOLT OUTER DIAMETER

Measure outer diameters (“d1 ”, “d2 ”) at two positions as shown
in the figure.

If reduction appears in “A” range, regard it as “d2 ”.

If it exceeds the limit (large difference in dimensions), replace
main bearing cap bolt with new one.
CONNECTING ROD BOLT OUTER DIAMETER
VQ23DE

Install nut to connecting rod bolt, and make sure if the nut can smoothly tighten until the end of screw
thread by hands.
