A bearing isolator seal (20) having a shaft seal assembly that includes a stator housing (30) comprising two components (40, 42) being selectively connectable and axially positionable and a rotor (32). The assembled stator housing (40, 42) has an inner radially extending face (80, 82) with a pair of spaced concentric annular flanges (72, 74, 76, 78) and the rotor (32) has a peripherally extending radial flange (60) with a contact sealing surface (64, 66, 68, 70) that contacts the free end of the annular flanges (72, 74, 76, 78) of the stator housing (30). Radially extending grooves (90) are provided in the rotor (32) so as to cause lubricant to be propelled radially outwardly through axially extending holes forming drain ports (94) under dynamic sealing conditions. Methods for achieving desired axial clearances for both the original and the replacement rotors (32) are also provided.
