ABSTRACT:
An endplay structure is provided for controlling endplay of a shaft25of a motor19. The endplay structure includes a body22including a generally elliptically shaped recess26therein. The recess is constructed and arranged to be disposed generally adjacent to an end of the shaft. An engagement member28has a generally spherical portion constructed and arranged to be received in a press-fit arrangement with the recess. The engagement member has a surface32constructed and arranged to contact the end of the shaft. Whereby, when the surface of the engagement member is contacted by the end of the shaft, the spherical portion of the engagement member is press-fitted into the recess to control endplay of the shaft.
