Pressure Control Pilot (PCP) for Electric Displace-
ment 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 internal
screens.
4. Install new O-rings in PCP Housing. Place PCP
against EDC housing and install the screws. Torque
to 5.4 Nm (48 lbf•in).
Note: Do not remove black plastic cover from the
aluminum plate. This is not a serviceable item
and will void the product warranty.
Hydraulic and Electric Displacement Controls
1. Thoroughly clean external surfaces prior to removal
of control.
2. Using a 5 mm internal hex wrench, remove the eight
control mounting screws. Remove the control (with
orifice check valve and spring) and control gasket
from housing.
Caution
A sealing washer must be installed under the
head of any mounting screws that are installed
into "thru" holes in the housing.

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 assembly
left and right to check engagement of pin in the link.
Proper engagement will be indicated by an increas-
ing resistance as the control is moved away from
center position. Non-engagement of pin will be indi-
cated by lack of spring force. In case of non-engage-
ment, remove control and repeat the above proce-
dure.
6. Align the control gasket and install the screws. Torque
the screws to 16 Nm (12 lbf•ft).
