Hydraulic Displacement Control (HDC) and
Electric Displacement Control (EDC) Adjust-
ment
The “neutral” adjustment is the only adjustment that can
be made on hydraulic and electric displacement controls.
All other functions are preset at the factory.
This adjustment must be made on a test stand or on the
vehicle/machine with the prime mover operating.
The neutral adjustment is performed by adjusting a
neutral adjusting shaft (earlier production EDCs) or a
neutral adjusting screw (HDCs and current production
EDCs).
WARNING
The following procedure may require the vehicle/
machine to be disabled (wheels raised off the ground,
work function disconnected, etc.) while performing
the procedure in order to prevent injury to the
technician and bystanders. Take necessary safety
precautions before moving the vehicle/machine.

1. Install two 50 bar (or 1000 psi) gauges in each of the

draulic or electronic) from the control. Start the prime
mover and operate at normal speed.
2. Loosen the lock nut with a 17 mm hex wrench for the
neutral adjusting shaft or with a 10 mm or 13 mm hex
wrench for the neutral adjusting screw.
