A PROCESS AND MEANS FOR THE FILLING AND SEALING OF THE LUBRICANT RESERVOIR LOCATED WITHIN THE PIVOT OF LUBRICATED TURNING PAIRS, IN PARTICULAR TRACK LINK PIVOTS AND CRAWLER TRACK ROLLERS

摘要

The invention's application is suited in particular to the lubricated turning pairs of crawler tracks. It makes provision for the sealing of the lubricant reservoir by means of an elastomer plug, and for the introduction of a needle into and through the plug. The needle serves to effect evacuation of any existing air from within the reservoir, and the subsequent introduction of lubricating oil. The needle is then withdrawn from the plug which, by virtue of the elastic properties of the elastomer, automatically re-encloses the puncture produced by the needle.
