9.3.5 Hydraulic and Electric
Displacement Controls
1. Thoroughly clean external surfaces prior to re-
moval of control.
2. Using a 5 mm internal hex wrench, remove the
eight control mounting screws. Remove the con-
trol (with orifice check valve and spring) and
control gasket from housing.
CAUTION
Protect exposed surfaces and cavities from
damage and foreign material.
3. In preparation for installing the control, place a
new gasket on the housing. Inspect to ensure that
the control orifice check valve and spring are in
their proper position in the control.
4. While setting the control into position, engage the
pin on the control linkage into the mating hole in
the link attached to the swashplate.
5. With the control in position, move control assem-
bly left and right to check engagement of pin in the
link. Proper engagement will be indicated by an
increasing resistance as the control is moved
away from center position. Non-engagement of
pin will be indicated by lack of spring force. In case
of non-engagement, remove control and repeat
the above procedure.
6. Align the control gasket and install the screws.
Torque the screws to 16 Nm (12 ft•lbf).
NOTE: A sealing washer must be installed under
the head of any mounting screws that are installed
into "through" holes in the housing.
9.3.6 Pressure Control Pilot (PCP) for
Electric Displacement Control
1. Thoroughly clean external surfaces of control.
2. Using a 4 mm internal hex wrench, remove the
four screws and remove the PCP.
3. Check surfaces for nicks or damage. Clean inter-
nal screens.
4. Install new O-rings in PCP Housing. Place PCP
against EDC housing and install the screws.
Torque to 5.4 Nm (48 in•lbf).
NOTE: Do not remove black plastic cover from
the aluminum plate. This is not a serviceable item
and will void the product warranty.
