ABSTRACT:
An external metal housing (10) is formed of two abutting metal plates (11, 12), each having a perimeter support wall (13) and an outwardly extending annular protruding wall (14) defining a bushing receiving area. An internal annular bushing (22) is accommodated within the receiving area and has two annular grooves (28) receiving two O-rings (30). A zerk fitting (38) extends through a closed-edge opening (16) of the external metal housing (10) and threads through the internal bushing (22) to deliver lubricant directly to the internal cylindrical surface of the internal annular bushing and to the facing surface of a camshaft extending through said internal bushing. The bushing is made of molybdenum impregnated nylon.
