A device (10) particularly suited for use for purposes of effecting the rotation of a reactor coolant pump motor (12) and flywheel (18) when the latter is required to be rotated, as for instance, in order to accomplish an ultrasonic and eddy current examination of the flywheel (18). The subject device includes housing means (20) of a multipartite construction capable of being secured in surrounding relation to the shaft (16) of the pump (12). Within the housing means (20) there is provided ball bearing means (26) and driven gear means (28). In addition, the subject device (10) also includes drive motor means (30) that is operatively associated with a drive gear means (36). The latter drive gear means (36) of the drive motor means (30) is supported in cooperative relation with the driven gear means (36) of the housing means (20) such that rotation of the drive motor means (30) is imparted to the drive gear means (36) and therefrom to the drive gear means (28). In turn, the rotation of the driven gear means (28) is imparted to the shaft (16) of the pump (12) thereby causing the rotation also of the pump motor (12) and flywheel (18), and hence enabling the desired examination of the flywheel (18) to be had.
