ABSTRACT:
An annular oil lip seal extender is used to axially reposition a conventional lip seal with respect to a rotating shaft after a wear groove is formed by the rubbing interaction between the lip seal and shaft without the need for a new seal, a new or reground shaft, the use of unreliable thin walled sleeves that fit over the shaft, or overly complicated assemblies that are prone to failure. The extender can be press fitted into the seal and the sub-assembly installed into a conventional housing bore. Alternatively, the extender can be loose fitted into the housing bore and the seal press fitted between the extender and the circumferential extending wall of the housing bore.
