Narrative
During the morning read up the operator discovered that the mixer on tank 3112 was leaking oil from what appears to be the mechanical seal area. Mixer was shut off, a bucket was placed under the mixer to contain crude release. Bolt backed off which connects mixer shaft with drive yoke. Once mixer shaft and yoke separated it allowed the shaft to move forward into the tank. Mechanical seal separated causing oil to fill gear box housing and over flow.
