I would rent or Buy a rotary hammer (or as Ryland knows it a chip hammer)
as Ryland suggested , and make short work of the motor joints.
The Professional demo tool is called a rotary hammer and not a hammer drill which is much cheaper/lighter/weaker/slower
A rotary hammer will turn concrete / motor into dust in 1 second , wear a dust mask !
They are lighting fast and can be had for cheap (harbor freight for instance).
