My rebuild Yaesu process:
Clean the races thoroughly. If there are some ball divots in the
aluminum, use some 180 grit sandpaper to reduce them, perfection isn't
needed. Replace the bearing balls with stainless ones from McMaster.
Lubricate with full synthetic TFE loaded SuperLube. Lightly lube the
gears also.
Getting the "timing" correct of the potentiometer vs the gears is
important. Hopefully, you marked the cases before separating and didn't
move the pot. It's confusing to get aligned if off.
If the controller pointer o-ring "drive belts" are flabbed out
(sticky/nfg pointer), my solution was to toss it into the nearest trash
and buy an RT21 from Green Heron. Fixing a Yaesu once was enough.
Yaesu mechanics are worth fixing.

Keith,
Since you took it apart, if you think you can put it back together I would recommend
you clean it up and, provided you believe replacement of the bearings will make it
work as it should, put it back together and see what happens. It will cost next to
nothing for 98 3/8” ball bearings. If you then want a new one to have the most
reliable option, you will still have something you can sell if it works.

Keith,
I have yet to see any place repair Yaesu rotators. I have a G-2800SDX that has
been chugging for many years. Originally it turned a C-4XLD but now handles a
4-L SteppIR. If it ever fails, I will replace it like-for-like. Note well that
there are other choices to be had. Good luck in your quest.

I have a Yaesu G-1000 rotator. It was installed on my 150 foot tower
in 1999 to turn a Force12 C-4XL. Over the years the antenna has
sustained a lot of damage from three hurricanes and several lightning
strikes. My tower climber took it down and also removed the rotator,
which stopped working some time ago. I took the rotator apart and
discovered that all of the bearings are rusted. I assume they are
ruined.
Would it be advisable to find someone to repair the unit, or just
purchase a replacement?
