SWASHPLATE NEUTRAL ADJUSTMENT
Using a low pressure line (500 psi min.), cross-port servo port "F" to servo port "B". This removes the effects
of any control pressure on the servo piston.
Install pressure gauges (10,000 psi) in the system pressure gauge ports. Start the prime mover and slowly
accelerate to normal operating RPM.
Remove the protective cap and loosen servo lock nut while holding the servo adjustment screw in position.
Turn the servo adjustment screw until the two system pressure gauge readings are equal.
Turn the servo adjustment screw clockwise until one of the system pressures starts to increase. Noting the
amount of rotation, turn the servo adjustment screw counter-clockwise until the other system pressure start to
increase.
Turn the servo adjustment screw clockwise half the amount of rotation noted above.
While holding the servo adjustment screw from turning, torque the servo lock nut to 13 - 18 Ft. Lbs. Stop the
prime mover, install a new protective cap, remove the servo cross-port line, and proceed to the appropriate
control adjustment.
