Someone please help
 

I need to know if you remove the ball bearings when you take out the back rolling pins in the drill motor. Iknow that you have to tap those six holes inside the motor but what size is the tap and what size set screws do we use?


Thanks Ty

"tap the 6 holes with an M-6 Tap and replace the balls with M-6 set screws "

Look up Dr. Joe's drill advice in the white paper section, and it's right there.
