pull tabs 52 a pulling force can then be applied to the tool 60 to urge the ears 64 against the inner pull surfaces 58 of the pull tabs 52 to draw the inner case 16 and thus the seal assembly 10 axially out of the bore 20 the combined views reveal that when the pulling force is applied to the tabs 52 the force will be transmitted through the inner case 16 to the outer case 12 specifically through the cylindrical portion 40 abutting the outer end 46 this cooperative action results in the entire assembly 10 will be removed by the application of the pulling force on the tabs 52 also the application of the pulling force will be concurrently directed to both cases 12 16 and will thus not affect the compressive load acting on the sealing element 18 fig5 and 6 illustrate an alternative embodiment where an inner case 16 u2032 is shown having the same general l shaped configuration including cylindrical portion 40 u2032 and flange portion 42 u2032 with clamping surface 44 u2032 as that of the first embodiment and with primed numbers being used to represent like or similar features as those of the first embodiment of the inner case 16 the inner case 16 u2032 also includes a plurality of pull tabs 52 u2032 extending from the mouth edge 54 u2032 however in this second embodiment the pull tabs 52 u2032 are stepped such that the inner pull surface 58 u2032 is generally parallel to the clamping surface 44 u2032 or perpendicular to the surface of the shaft or the cylindrical portion 40 of the inner case or generally perpendicular to a longitudinal axis a of the inner case 16 u2032 this stepped configuration includes an offset.
