Crankshaft 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 color of its journals are painted 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 Number 1.









From the above table, select a bearing whose size is appropriate for the crankshaft journal outside diameter. If the crankshaft journal outside diameter ID color is "yellow" and the cylinder block bearing bore ID mark is "III," for example, select a bearing whose ID color is "green" [Number 1, 4] or "red" [Number 2, 3].
If there is no ID color paint on the crankshaft, measure the journal outside diameter and select a bearing appropriate for the measured valve.
