Remove bearing cap and bearings. Measure plastigage width using the scale on the plastigage bag.
NOTE: The procedure when the measured value exceeds the repair limit is the same as that described in "Method of Measurement".
CRUSH HEIGHT OF MAIN BEARING
^
When the bearing cap is removed after being tightened to the specified torque with main bearings installed, the tip end of the bearing must
protrude.

MAIN BEARING CAP BOLT DIAMETER
^
Check for bolts (M9 and M12) installed from lower side using the following procedure.
NOTE:
^
Side bolt (M10) is outside the target.
^
Figure shows M12 bolt.
^
Measure bolt diameter "d1" from tip of the bolt to dimension "a".
^
Measure bolt diameter "d2" from the dimension between tip of the bolt and dimension "b" as base station to dimension "c".
NOTE: If a narrower part in the threads is determined by visual check, measure "d2" at that point.
^
Calculate the difference between "d1" and "d2".
