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. Refer to "ASSEMBLY" for the tightening procedure.
Standard: There must be crush height
^
If standard is not met, replace main bearings.
MAIN BEARING CAP BOLT DIAMETER
^
Check for bolts (M9 and M12) installed from lower side using the following procedure.
NOTE:
^
Side bolt (Ml0) 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".
