8.3.2 Displacement Limiter Adjustment
(MV)
Both the maximum and minimum displacement may
be limited. For description see Sec. 2.6.2.
1. Remove the tamper resistant cap from the dis-
placement limiter screw. Loosen the seal lock nut
retaining the displacement limiter adjusting screw
with a 19 mm wrench.
2. Rotate the adjusting screw with a 6 mm internal
hex wrench. Rotating the maximum displacement
adjusting screw clockwise will decrease the maxi-
mum displacement of the motor. Rotating the
minimum displacement adjusting screw clock-
wise will increase the minimum displacement of
the motor.
WARNINGS
Care should be taken in adjusting displace-
ment limiters to avoid undesirable flow or speed
conditions. See Sec. 3 for speed and pressure
limits.
The seal lock nut must be retorqued after every
adjustment to prevent an unexpected change
in operating conditions and to prevent external
leakage during unit operation.
3. After establishing the desired displacement set-
ting, tighten the lock nut on the adjusting screw to
54 Nm (40 ft•lbf). Install a new tamper resistant
cap.
4. One turn of the adjusting screw will change the
maximum or minimum displacement according to
the following chart.

The displacement limiters act as travel stops
for the swashplate. Do not turn the limiter
screws counterclockwise beyond the point of
contact with the swashplate for either the maxi-
mum or minimum displacement position.
