Message: [QUOTE="Bunya, post: 1203847, member: 77196"] The journal is is the part of the crankshaft that rides inside the bearings. They are typically damaged when the main bearings seize and the crank continues to spin inside the ID of the bearing. This causes galling and tremendous heat. Because the crank is softer than the bearing, the galling removes metal from the crank, reducing it's OD. As a result, when the bearing is replaced there may be excessive clearance. Over time even a crank that's undersize by only .001" will get hammered oblong and start to cause problems. When you pull it apart the damage should be obvious, but it's possible it will look fine. Mine looked almost new, but when I measured it with a micrometer I found the flywheel side was oblong and .004" undersize inline with the crank pin. [/QUOTE]
