CHAPTER VIII 



LUBRICATION AND CARE OF THE 

 SEPARATOR 



THE life of the machine depends largely upon the 

 thoroughness of its lubrication. This is especially 

 true of the steel separator, which does not fail 

 from rotting. A light oil with good wearing qualities 

 should be used. Thin oil is surer to reach the place it 

 is intended to lubricate than thick, heavy oil. A journal 

 is more apt to be continually lubricated when a small 

 amount of oil is applied frequently than when a great deal 

 is used at longer intervals. Many of the oil boxes on the 

 machine, as for example those on the rock shafts, may be 

 partly filled with wool or cotton waste. Either will keep 

 out dirt and make them hold oil longer. This wool or 

 waste should be renewed at the beginning of each season 

 and more frequently in localities in which there is sand. 

 Use a nail or soft wire to clean out oil holes, for if a piece 

 of steel be used when shaft is running, it is liable to "score" 

 and injure the journal. 



Hot Bearings. The causes of hot bearings are : I In- 

 sufficient lubrication because of too little or too poor oil or 

 hole being stopped up; 2 dirt or grit on the journal ; 3
