I hope someone can point me to the obvious here. I recently purchased a late 90’s Mazak Multiplex. Unfortunately the original owners shipped the machine with the Master Jaws removed from the chucks.
In 35 years I have never has to remove Master Jaws from a power chuck so I am at a loss as to how to reinstall them. They are numbered as is the chuck so I know how to match them up for the correct location but this appears to be just like a manual chuck with the scrolling drive for the jaws (not a t-nut and serrated land type of jaw like my past hydraulic chucks) There appears to be an offset “Allen Key” type of drive bolt that would appear to drive the scroll to install these jaws just like an ordinary 3-jaw manual chuck however the Allen Key drive bolts refuse to move (could they be locked by opening or closing chuck pressure?)
Or do I need to remove the chucks from the machine and dis-assemble them to reinstall the Master Jaws (This doesn’t make sense as this would require substantial effort that I doubt the former owners would do)
Surely there is something or some trick to this.
Any help would be greatly appreciated.
Kind Regards
