Abstract
A lubrication system designed particularly for small universal joints is provided. It includes a central distribution insert with a system of vertical and transverse passage 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. Preferably, when the lubricant reaches the distribution insert after the last trunnion, it is directed to a fitting in the distribution insert which is connected via a hose or the like to a container for collecting any excess lubricant. As a result, the uncontrolled discharge of the lubricant into the environment is avoided. 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.
