Replacing a Makita drill chuck is the same as replacing most other brands of drill chucks. The key is getting the chuck to release from the spindle after removing a screw that secures the chuck. Once you remove the faulty chuck, take it to a Makita dealer or a home-improvement center. Purchase a chuck that matches the old one for a good fit on your Makita drill.

Step 2

Twist the drill chuck counter-clockwise to open the chuck jaws. Look inside the middle of the chuck, and locate the screw that secures the chuck to the spindle.

Step 3

Remove the chuck's securing screw with a Phillips-head screwdriver. You must turn the screw in a clockwise direction because the screw is a left-handed thread.


Step 4

Insert the short end of a 1/4-inch or larger Allen wrench into the chuck, and tighten the chuck around the wrench as you would with a drill bit. Tighten the chuck around the Allen wrench, using the chuck key.

Step 5

Lay the Makita drill on its side, with the long end of the Allen wrench pointing to the left. Strike the Allen wrench with a hammer to turn the drill chuck counter-clockwise. Twist the chuck off the spindle by hand.


Step 6

Thread the new chuck onto the spindle, and open the chuck jaws fully. Secure the chuck to the spindle with the retaining screw. Turn the screw counter-clockwise to tighten. The chuck will seat itself the first time you use the drill.
