Question and Answers

Q:

Is the chuck threaded right or left to the shaft 900.271021

A:

Thank you for the inquiry and for using ManageMyLife.com. I know how frustrating it can be to have what seems like an easy install turn out to be more complicated. I have outlined below the installation instruction you can follow to replace the chuck, hopefully this will help.

Drill Chuck Installation:

  1. Disconnect drill power cord from electrical outlet.
  2. Place the directional switch into the center "Lock" position. The directional switch is in front of the trigger.
  3. Place the short end of a 5/16-inch Allen wrench into the chuck and tighten the chuck around the wrench with the chuck key.
  4. Tap the Allen wrench with a hammer or mallet to loosen the screw that secures the chuck to the drill. Use the chuck key to remove the drill chuck jaws away from the Allen wrench and open the chuck jaws all the way.
  5. Insert a small flat head screwdriver into the center of the drill chuck to remove the screw securing the chuck to the spindle. The screw has left-hand thread, which will require turning the screw in a clockwise direction.
  6. Insert the Allen wrench into the drill chuck again and tighten the chuck jaws around the Allen wrench. Turn the chuck counterclockwise by tapping the Allen wrench with a hammer. Once the chuck is loose, remove the Allen wrench and twist the chuck off by hand.
  7. Thread the new chuck over the drill spindle and open the chuck jaws. Insert the securing screw and tighten the screw with the flat head screwdriver. Turn the screw counterclockwise to tighten the screw.
  8. Insert the Allen wrench into the chuck and tighten the chuck jaws over the Allen wrench. Turn the chuck in a clockwise direction by tapping the Allen wrench with the hammer. Release the Allen wrench from the chuck and tighten the securing screw one more time with the flat head screwdriver.

If you have any further questions or inquiries, please don't hesitate to ask. Thank you for using ManageMyLife.com.
