   I put a keyless chuck on an older corded Makita drill motor. Easy.

   Tried it on an old Makita cordless with no luck. I couldn't get the retaining screw out of the old chuck. Had a socket type (allen head) screw and it got rounded out. Not worth the trouble to continue on that drill.

   I wonder how long your motor will hold up mixing joint compound if it only had a 5/16 chuck to start.

   I know I could replace the chuck easily enough, but I was wondering about going up in size.  As for the motor holding up, I don't use it very often, so I'm not really worried about that.  The drill is prety old and beat up, so mixing mud is all I really want it for anyway.

   Depends on whether it's a standard size/configuration shaft. If so then you should be able to install a new generic chuck, or one scavanged off a non-functioning drill. If not, not.

   Note that if the old drill is not reversible then it generally won't have the lock screw down the central shaft -- it's held on by a simple left-hand thread. The standard scheme for a reversible drill is the same left-hand thread on the chuck, but a right-hand screw through the center of the chuck jaws and into the shaft.

   Getting the chuck unthreaded is of course a "challenge". Some come off quite easily, others are essentially impossible to remove after decades in place.

   But if you have to buy a new chuck it's probably not worth it. You can buy a new cheap drill for under $20 or so, or pick one up at a garage sale for $5.

   I found the easiest way to get the chuck un screwed is to chuck up an allen wrench and give it a SHARP rap. That works pretty well most of the time.
