If that's (clutch) the problem, a replacement from Yaesu was not available (call as this may have changed).
I got a pinion gear from a micromachine shop over in England. Like $15 including shipping. Not an exact fit, but very, very close.
The load (antennas) need to be well balanced for this to work. Motor won't start a pre loaded gear train.

Hi Dave, I saw that. My problem I hearing from a private reply is in the clutch. I also discovered from a direct reply back to me there is an exploded view in the G-5400 manual. See…..

Good ol FoxDelta saved the day!
I’m going to get back on it tomorrow morning and see if my G-5500 is close enough to the diagram to take apart. I’ll report back here to the group with my findings….

Jeff,
Not sure if this will be any help to you or not.

I removed the rotor from the tower today and started working on the azimuth rotor. When power is applied via left or right control the motor is running. I carefully split the case and everything appears intact. Grease is still good, no missing gear teeth, no metal shavings in bottom of housing. So the problem is somewhere in the gearing, or mechanical control. I would like to proceed further but have no exploded view of the inside of the rotor. I wouldn't want to proceed without some kind of service manual part description view. Does anyone have anything that might help? Does anyone have a clue, maybe had this same problem and fixed it?I already have the useless Yaesu user manual..
