thank you

I'm really sorry, I hit the wrong key, and didn't notice. My drill / mill is an Enco 105-1145 not an Emco. Thank you for trying to help.
 
Here is the manual:

Looks like item 66 and 67 is what you need to tighten. Look at the nut and find the knotch where the lock washer ear is pushed into it. Take a thin flat screwdriver and pry open the ear is in and carefully tighten the nut. If you have a hook spanner (gane use a punch made from leaded cold roll if thats all you have. Do not use brass as it will chip off and end up in the bearing.tighten it so another knotch lines up. Test it, then do it again if you have too. Getting it to tight will scrw up the bearings. Good luck. Rich

I have what looks to be the same machine, different badge, the manual is not much use. Without taking the head off I don't know but I am assuming it is a taper lock bearing. Measure it if you can, even better get a makers number off it. Go to a bearing shop or if you have a bearing book, cross reference it to a well known brand such as Timken or SKF. They will have a tolerance guide, when you tighten up they will give a tolerance where you can just fit a .001" or .0015" (these figures are from memory) feeler gauge between the rollers and the race. That is what you lock the nut on. "by guess and by God" will work but you run the risk of overtightening and your bearing will not last.

I have been happy with the customer service I have recieved from Enco, they have always taken care of any problems I might have with their products. But, and this is a big one to me, They don't seem to spend a dime on service manuals, or back up information. How do they expect the average hobby machinist to be able to maintain the machines that they sell. I am confident that I can take the mill apart, but it would be nice to know before hand if there was a correct procedure, or if there were any special tools needed. Another example of this lack of interest in their machines, after they are sold, are the oilers that get more oil on the user and the floor without getting a drop into the machine.
