Smoke coming from the vents of my drill

[bigcee352]

My dewalt Dc 759 cordless 18 volt drill is starting to smoking a whole lot now.
I took it apart and cleaned up and put it back together and squeeze the trigger for a little while and again smoke started to come out. It seems that it's over heating or something.
can so one tell me whats wrong?

Hey bigcee352,
most likely your motor is bad..
part # 397156-02 available at ereplacementparts.com..
also check your switch for a burning smell..
hope this helps..
