I have a milwaukee 1675-1 hole hawg and the switch is bad and was wondering is there a way to test the motor to make sure it is good

To remove the spindle on a Milwaukee Hole Hawg 1675-1 drill, you will need to follow these steps:

1. Disconnect the drill from the power source and remove the chuck key.
2. Turn the drill over so that the chuck is facing upwards.
3. Locate the spindle lock button on the side of the chuck.
4. Press the spindle lock button and hold it down while rotating the chuck counterclockwise to loosen it.
5. Once the chuck is loosened, you can remove it from the spindle by pulling it off.
6. To remove the spindle from the drill, you will need to loosen and remove the retaining bolt that holds it in place. The retaining bolt is typically located on the bottom of the drill, near the front of the spindle.
7. Once the retaining bolt is removed, you should be able to lift the spindle out of the drill.

It is important to follow these steps carefully to avoid damaging the spindle or the drill. If you are having difficulty removing the spindle, you may need to consult the owner's manual or a certified mechanic for assistance. They will have the necessary tools and expertise to help you remove the spindle safely.

Gear box issues.

Go to e replacement parts and put your model number in and this will get you a parts break down.

Look down the barrel of the chuck, there should be a setscrew (usually torx)
this should unscrew counter clockwise. The chuck should also unscrew counter
clockwise with some coaxing. Hope this helps.
