I'm about to disassemble a Yaesu G5550 Azimuth Rotor to replace the Starting Capacitor. Has anybody done this and can give any suggestions? I'm concerned about taking it apart and a million pieces falling out
Thanks

You can put the cap at the control box but if you want to take the rotator apart.
1. Turn it upside down and unscrew the 4 screws that hold the ball bearing racier.
2. Turn it right side up set it on the desk holding the bearing ring in place
3. With the unit on the desk slide the bearing ring down and lift the rotator out of the bearing racier. Be careful not to lift the top of the rotator off the body of the rotator
4. Turn the rotator upside down and set it on the desk.
5. Lift the body of the rotator off the top of the rotator.
If you get the sequence wrong the ball bearings' will fall out no big deal just capture the all the bearings and put them back in the racier.
Call if I have confused you

Hi Paul,
If the Starting Capacitor of your Yaesu G5500 Azimuth Rotor is not shorted out but it only loosed capacity and it only looses torque and some time stops I suggest you do not dissamble the Rotor.
Simply connect a 100 uF 50 Volt AC unpolarized electrolitic capacitor across terminals A4 and A5 on the rear screws of your control box.
From the electrical point of view it is the same to dissamble the Rotor
and put the capacitor inside of it.
If you don't own an AC electrolitic capacitor built it by your self following the schematic diagram belove:
C1 C2 - + + - |--------) |------|------| (--------| A4 ------| | |------- A5 |-------|>|------|------|<|--------| D1 D2
where:
C1 and C2 are 100 uF 100 volt DC capacitors
D1 and D2 are any diode like 1N4007

Yes, The easiest way -unless the cap in the housing is shorted- usually not, just not enough capacitance left to do what it was supposed to do...Put the cap in the Control box. That is how most of the rotors function anyway. Good Luck... 73, Dee, NB2F NJ & NA AMSAT Coordinator

Don't forget to lube it while you have it apart.
I did. Despite my assumption it was the cap it in fact was not.
There's a strangle little spring that's part of the coupling between the motor and the first drive cog. Not sure why its there, but it had slipped out of position and was jamming the motor. I was tempted to leave it out (as it seemed it would work fine with out it), but put it back in any way and all is working fine. If it happens again I'll remove the spring for ever.
