Abstract

To install an elastomeric seal (6) element having a radial lip (34) over a cylindrical sealing surface (30), the radial lip is expanded over a cylindrical exterior surface (62) on a mandrel (60) and the sealing surface is aligned with the exterior surface of the mandrel. The mandrel has axially directed grooves (66) that open out of its exterior surface, and these grooves are from within the mandrel filled with grease (g), which deposits on the radial lip where the lip traverses the grooves. Thereupon, the seal element is pushed off the mandrel and onto the aligned sealing surface.
