Abstract
A lubricating arrangement for an end guide of a railcar truck mounted brake rigging includes at least one elongated groove provided in the at least one surface of the end guide in open communication therewith, the elongated groove having a length thereof disposed generally transverse to a direction of the sliding reciprocal movement of the end guide. A lubricating member is secured within the at least one elongated groove, the lubricating member has a thickness portion thereof protruding, a predetermined height at initial installation, above the at least one surface of the end guide. The predetermined height of the protruding thickness portion is reduced during the reciprocal movement of the end guide within the channel or pocket so that material removed from the predetermined height during the reciprocal movement substantially resurfaces the at least one surface of the end guide.
