ABSTRACT:
A removable end cap closure member or welsh plug for bearing units is disclosed including a frangible knockout plug adapted to be broken out of the closure member with an impact tool to provide an aperture allowing removal of the closure member with a tool. In the preferred embodiment, the plug remains attached to the closure member by a bendable connecting neck which prevents lodging of the plug in the bearing unit.
Also disclosed is a bearing assembly including the removable end cap closure member as well as a method for removing the closure member including pressing the knockout plug with a tool to provide an aperture in the closure member and prying and bending the closure member away from the bearing unit with a tool inserted in the aperture. A fixture for supporting a trolley wheel and trolley bracket assembly during installation and removal of an end cap closure member to and from such an assembly is also disclosed.
