LUBRICATION AND CARE OF THE SEPARATOR 223 



girt and circular piece of sheet-steel on the left-hand side 

 are removed and the beater taken out through the hole 

 thus created. 



To Remove Rock-Shafts. The rock-shafts are en- 

 larged at one end so that when the set-screws are loosened 

 they may be readily removed. The front rock-shaft is 

 straight and can be taken out at the left side of the ma- 

 chine by removing its left-hand box and simply loosening 

 the set-screws in the vibrating-arms. The rear rock-shaft 

 is bent and is taken out by loosening the set-screws and 

 left-hand box and moving the shaft to the left until out of 

 the right-hand arm, then to the right until out of the left- 

 hand arm. 



To Remove the Straw-Rack. Take off the tailer-rack, 

 pan and rock-shaft, if these parts be on the machine. Take 

 off the four straw-rack boxes, the bolts of which can be 

 easily reached with a socket-wrench through the openings 

 for vibrating-arms. The rack can then be taken out 

 through the rear of the machine. 



To Remove the Grain-Conveyor. Take out the bolts 

 holding rear straw-rack boxes and fasten rear end of straw- 

 rack to deck of separator. Remove the rear rock-shaft 

 as already explained. Then raise the rear end of the con- 

 veyor and remove the rocker-arms through the opening in 

 separator sides. Next, take out the bolts in front con- 

 veyor-boxes and drop the conveyor so that the boxes may 

 be taken off their studs on the rocker-arms. The conveyor 

 can then be removed through rear of separator.
