Crankshaft Main Bearing 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.





Install the bearings having an oil groove to the cylinder block.
Install the bearings having no oil groove to the bearing cap.
