Consult the factory for special requirements that must be met if the pump is  
to operate beyond one or more of the limits specified above.  
NOTE:  
In order to drive the pump from the side opposite the present  
shaft extension, simply remove the valve casing from the crank-  
case and rotate the pumps 180 degrees to the desired position.  
Be certain to rotate the seal case (item #20) as well, so that the  
weep holes are down at the six o'clock position. Exchange the oil  
fill and the oil drain plugs, also. Refer to the repair instructions as  
necessary for the proper assembly sequence.

Consult the factory for special requirements that must be met if the pump is  
to operate beyond one or more of the limits specified above.  
NOTE:  
In order to drive the pump from the side opposite the present  
shaft extension, simply remove the valve casing from the crank-  
case and rotate the pumps 180 degrees to the desired position.  
Be certain to rotate the seal case (item #20) as well, so that the  
weep holes are down at the six o'clock position. Exchange the oil  
fill and the oil drain plugs, also. Refer to the repair instructions as  
necessary for the proper assembly sequence.
