Enzo,
Unfortunately the rotators used in the G-5400 are not quite the same as the G-5500.
They both use a phase shift capacitor for full torque, and also a method of protecting the motor in case it hangs. In the G-5400, the azimuth rotator has the capacitor in the control box, and uses thermal limit switches. The elevation rotator has the capacitor located in the rotator housing, and uses mechanical limit switches. In the G-5500, both units have the capacitor in the rotator, and mechanical limit switches. For completeness, the original Kenpros, which Yaesu acquired, had the capacitors for both in the control boxes. There are reasons why mounting the capacitor remotes is better, but it is much messier to replace, and more likely to fail due to the temperature extremes.
73s,
