3-Jaw Chuck Removal Procedure
How can I safely get my 3-jaw chuck off my turning center?
Lower the pressure down to minimum so actuation is slow. When you are in the middle of the stroke hit E stop. Now remove all bolts but one, leave that one on by a quarter inch and use the chuck wrench to take the chuck off the draw tube adapter. If the chuck is heavy, get someone to help hold the chuck while you turn the chuck off the draw tube adapter.
