Abstract
A lubrication system designed particularly for small universal joints is provided. It includes a central distributions insert with a system of vertical and transverse passages which enable all four bearing cups and bearings to be sequentially lubricated from a single source. When all four are completely lubricated, lubricant appears at the top of the central distribution insert to assure that all cups have been fully lubricated. The lubrication system enables lubricant fittings to be positioned in four locations around the universal joint cross and also a central lubrication fitting can be located in the central distribution insert. The passages in the insert are positioned such that the insert can be made from one two-part mold without any mold inserts being required.
