Crankshaft

Fig. 10 Checking Main Journal & Crankpin Diameter:

1. Check crankshaft for cracking or damage. Replace as required.
2. Check crankshaft for runout, using a suitable dial gauge and V-blocks. If runout exceeds .0012 inch (.03mm), replace crankshaft.
3. Measure main journal and crankpin diameter for wear. If journal or crank pin diameter are not as specified in Fig. 10, replace or grind crankshaft to match an undersized bearing.
