83 If the motor’s minimum displacement is being
changed the number of shims under the servo piston
spacer may need to be adjusted. The following table
shows the required number of shims and the spacer bolt
length for each minimum swashplate angle. Theoretical
displacements are also given for each swashplate angle.
Important: Verifying the motor’s minimum displacement
on an authorized test stand is essential.
