The standard Morse taper dimensions for a drill chuck are typically designated as MT1, MT2, MT3, MT4, and MT5, with each size corresponding to a specific diameter and length for the taper.
Use a pair of Vise-Grip pliers on the key-less chuck and Channel-lock pliers on the stuck bit. Holding the drill with the drill facing away from you (as in use), turn the chuck clockwise and the bit counterclockwise.
The Morse taper dimensions chart provides information on the sizes and specifications of Morse tapers, which are commonly used in machine tools for securing cutting tools. This chart includes details such as taper angle, diameter measurements, and length dimensions for different Morse taper sizes.
first, has it been damaged, if no, then clean both parts as best you can, then use some chalk like the kind used in chalk lines, put a lite coating on the tapered part of the chuck, and put it in place, stack some wood under the chuck and use the drill press to gentle force the chuck in place. shoud last along time.ANS 2 Your average drill press chuck is held on to the spindle with a Morse Taper. To fit this simply clean both parts and tap it lightly on with a soft face hammer. The idea is that it can be changed quickly for other sizes.

I believe on that model the chuck would be a Morse taper fit. To remove it, extend the chuck spindle to it's lowest position and use a metal hammer to tap firmly ONCE on the top of the chuck. It should drop free. Make sure your new chuck is the same and clean the inside of the taper and the arbor taper with alcohol (NOT rubbing alcohol, -99 % alcohol) Then fit the dry chuck onto the arbor for a test fitting. If it slides on easily, raise the arbor to the top and line up the chuck with spindle, retract the jaws and tap once with a steel hammer upwards on the base of the chuck. It should seat on firmly and you are ready to drill.
