ABSTRACT:
A shaft extending along an axis through a bore in a body and forming with the body an axially outwardly open compartment has a seal assembly having an elastomeric sleeve-like seal seated in the compartment and a rigid sleeve generally coaxial with the seal. The seal has a plurality of inner peripheries bearing radially inward on the shaft and an outer end projecting axially out of the compartment. The sleeve is secured axially to the seal for extraction of the seal from the compartment by outward movement of the sleeve.
