After running my mill about 30 minutes making some very light cuts on aluminum I noticed the spindle bearing area was very hot (160), the main body of the mill was 79 degrees. Any idea what would cause this, oil levels are normal.

Where can I get information on how to tear it down?

First thing is to study a parts breakdown of the vertical head. Do you have one? You also might post the model of your K&T so someone familiar with it can step in to help...
 
Does it have grease fittings?? Any leaks by the spindle ?? Any hole with a plug an endoscope will fit in. There like $20. For a cell phone or tablet you can look without dismantling to a point. If it's grease you'll see it.
