I have purchased a G5500. The control box have a 117Vac label in the real
panel. I opened it and a wire is connected through the fuse to the terminal
number 3 of the KT-30 transformer and the other wire through the main switch
to the terminal number 1 of the KT-30 transformer.
I am wondering
I have an Yaesu GS-050 thrust bearing that has been installed for about 15
years. The thrust bearing turns, but requires a lot of force.
I disassembled the thrust bearing to find that the grease is very sticky (think
candy apple sticky), and not lubricative (if that is a word).

Justin,
Actually, the orbit is holding up pretty well for AO-51. The ISS is big
enough, and low enough, that drag is a significant factor. Drag is
_roughly_ 200 times higher for the ISS than AO-51. Even ARISSat-1, which
will start at the ISS orbit, will have a lifetime of much less than a

Hello Steve,
15 years outside in the weather is a long time. Options:
1. replace in kind with a new unit. Probably the most time effective and
cost effective approach.
The new one should last another 15+ years.
2. Soak the old unit in a solvent to loosen up all of the old grease and
flush
Hello Steve
What I have done in the past
Is to degrease it all and before assembly,drill and tap grease nipples in
the housing,just make sure you clean all the filings before assembly.Then
for regular maintenance you just have to give them a small shot of grease
with a regular grease gun.

Steve,
I worked with bearings for many years as a Gyro overhauler and radar tech
for Sperry. The bearings I worked with were all high quality and close
tolerance. If you want to, you can remove the grease with a degreaser and
repack. Unless it was used constantly spinning, I don't think it
I have both rotor manuals for G5500 - G5400/5600 Yaesu units. The
schematics for both DO NOT show any wiring changes for the transformers to
work on 117VAC or 220VAC. The manuals do say that there are Different
transformers for 117 and 220 VAC use. It even states that they should be
returned
Hi Steve,
I don't have any experience with rotors, but a car repair shop is going to
charge you an arm and a leg for something you can probably do yourself.
Go to AutoZone and pickup a can of heavy engine degreaser (the red can w/
orange lid is the good stuff). You can also pickup a can of

I own this thrust bearing but imho it is not worth investing time and material
in such a low cost item. Get a new one and save yourself time. Clean the old
one and sell it on ebay as used.

I use it for bearings, rotators and mast use. Always worked for me.

Here is the mod to change Yaesu rotors to 220v:

But perhaps yours has a different transformer if it uses pin 3 for 117v. In

Look closer--Wrong rotor and I imagine you jump the other connections
together to have the voltage correct.
Again, Check the G5500 manual.

The pdf say G5500 in handwriting and I know a guy who says he did this mod on
a G5500. But obviously the KT-30 must be a different transformer.

Hi Bill, NZ5N
I was looking at the schematic diagram

As I suspected the transformer has 4 wires coming off from the
primary windings.
In my opinion the transformer has two identical primary windings
