Crankshaft Main Bearing: Specifications

Main Bearing Cap
Engine Overhaul
Bearing cap bolt shank length 71.1 mm (2.79 inch)





Tighten the bolts to the specified torque in the tightening sequence shown.
Tightening torque 25 ± 2 Nm (18 ± 1 ft. lbs.)





Make a paint mark on the head of each bolt.

CAUTION:
If the bolt is overtightened, loosen the bolt completely and then retighten it by repeating the tightening procedure from step 4.
If the bolt is turned less than 90 degrees, proper fastening performance may not be achieved. Be sure to turn the bolt exactly 90 degrees.

Make a paint mark on the bearing cap 90 degrees from the paint mark made on the bolt, in the direction of tightening the bolt.
Turn each bolt 90 degrees in the tightening sequence specified in step 4, and make sure that the paint marks on the bolt and cap are aligned.

Main Bearing Size Codes





Measure the crankshaft journal diameter and confirm its classification from the following table. In the case of a crankshaft supplied as a service part, identification marks of its journals are stamped at the positions shown in the illustration.





The cylinder block bearing bore diameter identification marks are stamped at the position shown in the illustration from left to right, beginning at No.1.








For example, if the crankshaft journal outside diameter identification mark is "0" and cylinder block bearing bore identification mark is "1," select a bearing whose identification mark is "2" for number 1, 2, 4 and 5, and a bearing whose identification mark is "1" for number 3.
If there is no identification mark on the crankshaft, measure the journal outside diameter and select a bearing appropriate for the measured value.
