MOUNTING (continued)
MOUNTING THE NEW HARDWARE
1.
Recheck the series number on the control feedback link
to ensure that it is compatible with the motor. Follow the
procedure outlined below to install the linkage. See
Parts Location Drawing.
A.
Unscrew the bushing, using care not to damage its
O-ring. See Swashplate Assembly diagram.
B.
Install the new linkage assembly shaft through the
swashplate feedback shaft hole. Place the ball in
the crosslink ball cavity.

The control and feedback link must have the proper
identification in order to be installed. Installing a control
with an improper control feedback link can result in a
control failure which can cause the motor swashplate to
move to full angle and remain there independent of
signal input.
Do not attempt to install an EDC on a motor for which it
was not originally designed without changing the link-
and-ball assembly. Merely changing the swashplate
drag link is inadequate. See Ordering Information for the
necessary link-and-ball assembly number. In no case
should a valve originally built for a Series 2X motor be
used on a Series 3X motor.

SWASHPLATE ASSEMBLY

Pin Connection to Swashplate.
Shown Disassembled for Clarity.
C. Lubricate the shaft O-ring and replace the bushing
over the shaft. Torque to the body (10 - 15 foot
pounds) so that the feedback shaft extends through
the bushing.
D. Install the retaining ring in the groove on the shaft.
2.
Align one end of the replacement swashplate drag link
with the holes in the swashplate link arms.
3.
Insert the press fit pin through the case drain port to trap
the drag link in the swashplate clevis. It will be necessary
to tap the pin into place until the head of the pin is flush
to the clevis.
4.
Install the retaining ring by forcing it onto the tapered end
of the pin until it locks into the groove on the pin shaft.
Again, use caution not to drop any components into the
motor housing.
5.
Install the supplied spacer between the control and the
motor housing. If the motor is a 20 Series, the spacer is
one-quarter inch thick; if it is a 26 Series, the spacer is
1 1/2 inch thick. Other series' do not require a spacer.
One gasket and 3 O-rings must be installed on the under
side of the spacer.
6.
Install one .052-inch diameter orifice in each servo
passage if normal swashplate response is desired. Two
orifices are used instead of the single orifice used in the
charge supply passage of manual controls. Install 3 O-
rings and a gasket. If a spacer is used, there should now
be 6 O-rings and 2 gaskets in place.
7.
Engage the pin on the control in the drag link and swing
the control into place against the motor housing. The
drag link should be on the cylinder block side of the
swashplate. Install the seven mounting screws and
tighten to 10-11 foot pounds of torque.
