Parts That Could Cause The Dill Chuck Not To Open

Chucks 

The function of the drill chuck is to hold the drill bit. It has jaws to grip it firmly down. If it is closed, you can use channel lock pliers to release the jaws open. Then close the chuck and check if the jaws are evenly aligned. If they are not, hammer them to realign back to place. If the problem is not solved, it is best to replace the drill chuck with a new one.

If the chuck is open and stuck, then the screw inside the drill might be tight. You will need a screwdriver, a big Allen key, and a pipe to untighten. A loose screw in the chucks can prevent the teeth from moving. If so, remove the screw at the bottom. Using the reverse thread phenomenon, loosen the screw by turning the screwdriver clockwise. 

Once the screw is off, put the Allen key in place and make sure it is firmly tightened. Next, you take the pipe and insert it over the pass. This is for leverage. Turn it anticlockwise, and the drill chuck should open effortlessly.

Gear Cases

In case the chucks are in good condition, gear cases could be the problem. If you find out that the gears are not working correctly, you need to replace them. You should remove the cap on the drill then release the brush strings. Consequently, remove the screw clockwise while ensuring the transmission is at its lowest setting. Now, carefully insert the Allen wrench inside and tighten the chuck down on it. 

Using a hammer, hit the Allen wrench. Once the Allen wrench is loosened, remove all screws, including those securing the transmission clutch assembly. This will help you remove the cover, then clutch assembly, and pull the gear switch out. Replace the motor with a new transmission. Close all the components back to their rightful places and ensure all the wires are well tucked.
