Dear All,
Thank you for all the replies to this topic which is greatly appreciated.
In conclusion, I guess I will have to either (1) Replace the azimuth portion with a G-800 using a seperate control box for azimuth and elevation or (2) try to replace the azimuth portion with a G-450 rotor.
Has anyone successfully tried connecting the G-450 rotor motor directly to the G-5500 control box?

Sion,
I don't own a G-5500, but I do have both a G-5400 and G-800. The G-5400 and G-5500 are similar (not identical) judging from the manuals.
From looking at the manual for the G-5500, the azimuth rotor is completely different from the G-800. The G-5500 (and the G-5400) azimuth rotor is an AC motor with two coils and three wires for the motor. The G-800 is a DC motor with only two wires. (Both systems use an additional 3 wires for the position potentiometer, so five wires for the G-800 and six wires for the G-5400/G-5500.)
The G-450A rotor is similar to the azimuth half of the G-5500, judging from the manual. However, I'd look for someone who owns a G-450A who can verify that for you. The G-450A manual omits a schematic and some important specifications like the motor voltage. You may also be able to get some help from Yaesu customer service.

I have a Yaesu G-5500 rotator that has a spoilt azimuth motor while the elevation motor works fine. Looking at the specifications published by Yaesu, the G-800 rotator seems to be very similar with the azimuth motor of the G-5500.
Instead of purchasing a whole new set of G-5500 just to replace the spoilt azimuth motor (the control box is working and this has been verified with another working azimuth motor), I wonder if anyone has tried replacing the azimuth motor the G-800 instead?
Will the G-5500 control box work with the G-800 motor, are there some modifications needed, or is this simply not possible? Any pointers will be greatly appreciated.
Thank you.
