The thrust plate must be installed on the swashplate for
this measurement. Measure the distance from the end
cap mounting face of the pump housing to the face of
the thrust plate 900 to the trunnions, at the outer edge of
the thrust plate. Take the same measurement at a point
1800 (opposite edge of the thrust plate) from the first.
These measurements must not vary more than .001"
from each other.
If adjustment is required follow these steps.
a. Back out both servo housings until the spring load is
released on the swashplate (check by rocking
b. Thread in each housing until spring load just starts to
be felt on the swashplate.
c. Check measurements as described previously.
d. Thread each housing farther in until the
measurements are within .001" of each other.
After adjustment has been completed, the retainers can
be installed and peened into the locking slot on the
