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.
NOTES:
In order to drive the pump from the side opposite the present shaft exten-
sion, simply remove the valve casing from the crankcase 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.
