Abstract 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.
A rotor/bearing assembly replacement pack for a miniature high speed turbine of the type comprising a turbine housing having an internal chamber closed at one end by a threaded housing cap and a rotor/bearing assembly operatively mounted in said chamber; said pack comprising a container threaded at one end in correspondence with said threaded housing cap, a plunger slidably mounted in the opposite end of said container, a container cap closing said one end of said container, and a replacement rotor/bearing assembly mounted in said housing in correct orientation to be expelled from said container into operative position in a turbine housing chamber by depression of said plunger when said container cap is removed and said container is threaded onto the turbine housing in place of its housing cap.
