This drill chuck assembly is specially designed for use with Milwaukee compact driver drills. Its purpose is to secure drill bits. It is a keyless chuck that allows for quick and easy bit swap. The ratcheting action clicks the jaws tightly into place for reduced bit slippage. If your drill's bit retention is suffering, the rotation feels stiff, or the chuck has seized up entirely, a new chuck should fix the problem. Please note the screw used to secure this chuck it is sold separately.
To complete this simple repair you should only need a screwdriver.
• Make sure the unit is unplugged
• Remove the chuck retaining screw
• Remove old chuck and secure the new one
• Tighten the chuck retaining screw
• Test the tool

The part was perfect and arrived quickly. The replacement process was a bit complicated but the site's video was step by step, had great tips, and countered misinformation on other repair video sites.

Milwaukee drill chuck replacement
My old drill cruck jammed and I could not fix it. I watched your YouTube video on how to replace a drill chuck and it looked easy. The.replacement chuck you sent it to me appears to be an original Milwaukee part, and removing the old chuck and installing the new one was as easy as it looked on the video. Your price was competitive, and the cruck arrived on the predicted date. Life is good.

I watched the ereplacement video on You Tube. It made replacing the chuck much easier than I though it would be. I copied it for those that need to see it.

I first removed the screw that was at the bottom of the drill chuck. Which is a left handed thread. I then took a 3/8th allen wrench and put the short end where the drill bit would normally go. I then took a rubber mallot and hit the long end of the allen wrench to break the drill chuck loose. The threads on the chuck are right handed. It broke loose and all I had to do is unscrew it. The only other thing I did was put locktite on the screw I took out and put the left handed screw back in. It works fine now. Just to clarify the left handed screw is removed from the center of the drill chuck with the chuck opened all the way and the screw takes a large phillips screwdriver to remove it
