This video shows how to change chuck on a Bosch PBD 40 bench drill machine. I have always been unhappy with the original chuck but never really managed to remove it, I felt that it was practically impossible, so I suspected it was welded on the motor axis. I asked Bosch service and support about instructions on how to remove the chuck, but all they wrote back as answer was that I should send it in if I wanted to change the chuck and they will do it for me. Since that was NOT an answer to my question, I decided once more to try it, and this time, using an extension pipe, I managed to remove the old chuck. It really needed huge force, so I suspect Bosch used some sort of super glue just to piss off the users.

Anyway, no thanks to Bosch, I managed to replace it and decided to make a short video about it, in case somebody else also want to do the same thing and is too afraid to do it. It is really very simple, just watch how I did it.

Please note that when you order you must type in the right part number. Only the ones with 1/2"-20 mount fit this machine, and the one I am using is the 871050. That is very important when you buy the chuck.
