79 Position the motor so the mounting flange end is on
top. Stand it on wooden blocks so the other servo
sleeve can be adjusted. While the motor is in this
position the cylinder barrel will be setting on the wooden
blocks. Be sure to protect it from damage or
contamination.
80 Tilt the swashplate to the minimum displacement
position; the servo piston spacer should touch the
bottom of the servo sleeve.
81 Place the depth gauge on the mounting flange
surface so the gauge point is over the swashplate stop
pad.
The depth gauge must be a precise distance from the
center of the dowel pin hole in the motor housing, see
figure 30. Depth gauge positioning information is given
below:
82 Adjust the servo sleeve that is over the piston with
the spacer to get the desired depth gauge reading. Be
sure the swashplate is in the minimum displacement
position; the servo piston spacer must be touching the
bottom of the servo sleeve. Choose the depth gauge
reading for the desired minimum swashplate angle from
the table below figure 30.
