Crankshaft: Service and Repair
Service Procedures
A crankshaft which has undersize journals will be stamped with 1/4 inch letters on the milled flat on the No.8 crankshaft counterweight.
FOR EXAMPLE: R2 stamped on the No.8 crankshaft counterweight indicates that the No.2 rod journal is 0.025 mm (0.001 inch) undersize. M4
indicates that the No.4 main journal is 0.025 mm (0.001 inch) undersize. R3 M2 indicates that the No.3 rod journal and the No.2 main journal are 0.025
mm (0.001 inch) undersize.
When a crankshaft is replaced, all main and connecting rod bearings should be replaced with new bearings. Therefore, selective fitting of the bearings is
not required when a crankshaft and bearings are replaced.
