Information:
3400 Family Of EnginesFormerly, a large chamfer was machined on the oil holes in the crankshaft main and rod journals. See the illustration. A new smaller chamfer has been used for several years. To make the new small chamfer, a hand tool is used to break (remove) the sharp edge of the oil hole. Then the oil hole is hand blended smooth. The result may be a non-uniform small chamfer (when compared to the former chamfer) around the oil hole.
NO crankshafts should be reworked to provide the larger chamfer.
Comparison of chamfer on the current oil hole (A) and the former oil hole (B) in the crankshaft main and rod journals.
