Abstract
The tool housing-air motor assembly includes an air motor that is of modular design, that is, it is constructed so that the motor rotor is journaled in the cylinder by the end plates, which retain the motor in its operational alignment condition. The tool housing is used in the "as cast" condition without the necessity for performing any machining operations thereon. The assembly of the air motor and tool housing is possible since the motor is self-contained and does not rely on the tool housing for retaining the parts of the motor in assembled relationship or for retaining the motor parts in operational alignment.
