CHAPTER IX 

 THE TRACTION GEARING 



WHEN the traction gearing is used only in mov- 

 ing the engine from place to place, very little 

 attention need be given to it. When, however, 

 the engine is used for plowing or for hauling freight, the 

 gearing must receive careful attention in order to prevent 

 the possibility of expensive repairs. The parts which 

 require special attention on engines used for hauling heavy 

 loads are the lower cannon bearing and the bearing for 

 the intermediate gear. The pinions on the counter-shaft 

 should mesh properly with the gears on the traction 

 wheels. These may be set deeper into mesh on "Case" 

 engines by adjusting the turn-buckles in the links, called 

 "distance links," which connect the upper and lower can- 

 non bearings. The springs which carry the weight of the 

 boiler should not have too much leeway if the engine be 

 used for heavy hauling. 



Oiling the Cannon Bearings. A quantity of oil may 

 be poured into the upper and lower cannon bearings, which 

 will insure the lubrication of the axle and counter-shaft, 

 since it can only work out at the ends. The oil boxes 

 should be partly filled with wool or waste, and all other
