Abstract
A shaft extending from a housing is rotatably sealed with the housing using a split seal assembly. During installation of the assembly, an alignment pin on one half of the assembly engages an oblong recess with planar sides in the other half of the assembly to permit radial movement of the two halves toward each other while preventing relative axial movement between the two halves. The permitted radial movement facilitates the assembly of the seal to the shaft while the limitation on relative axial movement maintains the correct positions, of the two halves. The permitted radial movement allows the two halves to assume fill circular engagement with the shaft to optimize the seal and the mechanical engagement with the shaft.
