8.2.1 Standard Manual Displacement
Control (MDC) Adjustment
There are no adjustable elements in the manual
displacement control. The control spool is held in its
"neutral" position by centering springs and washers
on each end of the spool. Since there is no centering
spring on the control input shaft, the shaft will auto-
matically assume the appropriate position when the
control is installed on the pump.
