A rotor and bearing replacement pack or kit for a miniature high speed turbine, such as a dental handpiece, which includes a container holding a replacement rotor/bearing assembly oriented within the container in a predetermined position. One end of the container is closed by a closure cap threadedly received on the container. The cap-engaging threads on the container are matched to the threads which retain a housing cap in position upon the housing of the miniature high speed turbine. When the turbine housing cap is removed, and the closure cap is removed from the container, the container may be threaded into position upon the turbine housing in place of the housing cap. The replacement rotor-bearing assembly contained within the container is so oriented as to be in operative alignment with its final end position within the turbine housing when the container is thus threaded on the cap. A plunger operable from the opposite end of the container may then be employed to slide the replacement assembly into position within the turbine housing. The plunger is preferably tapered and can be employed to assist in removing certain parts of the rotor/bearing assembly to be replaced from the turbine housing. |
